str_repeat
Substituindo caracteres acentuados em uma string (português)
If you need change portugues chars to ansi chars, try this
$com_acentos=array(
"á","Á","ã","Ã",
"â","Â","à","À",
"é","É","ê","Ê",
"í","Í","ó","Ó",
"õ","Õ","ô","Ô",
"ú","Ú","ü","Ü",
"ç","Ç");
$sem_acentos=array(
"a","A","a","A",
"a","A","a","A",
"e","E","e","E",
"i","I","o","O",
"o","O","o","O",
"u","U","u","U",
"c","C");
$input_string = 'Ações em Alta. Série positiva:[áéíóúÁÉÍÓÚçÇ]';
$output_string = str_replace($com_acentos,$sem_acentos,$input_string);
echo 'input_string : ' . $input_string . " <br />\n";
echo 'output_string: ' . $output_string . " <br />\n";
-------------------
Your will get:
input_string : Ações em Alta. Série positiva:[áéíóúÁÉÍÓÚçÇ]
output_string: Acoes em Alta. Serie positiva:[aeiouAEIOUcC]

str_replace — Sustitiye todas las apariciones de una cadena en otra
Descripción
mixed str_replace
( mixed $cadena_buscada
, mixed $cadena_sustituta
, mixed $cadena_original
[, int &$veces
] )
Esta función sustituye todas las apariciones de la cadena_buscada en la cadena cadena_original por la cadena_sustituta dada. Si no precisa reglas especiales de sustitución (como por ejemplo expresiones regulares), deberá usar siempre esta función en lugar de ereg_replace() o preg_replace().
Desde la versión de PHP 4.0.5, todos los parámetros de la función pueden ser de tipo array.
Warning
En las versiones de PHP anteriores a la 4.3.3, existí un error cuando se empleaban matrices como parámetros cadena_buscada y cadena_sustituta que hacía que no se tuvieran en cuenta los índices vacíos de cadena_buscada y por tanto no se avanzara en la matriz de forma sincronizada con la otra matriz cadena_sustituta . Los scripts que estaban preparados para tratar este error, deben eliminar los valores vacíos de cadena_buscada antes de llamar a esta función para mantener el comportamiento original de la función.
Si cadena_original es una matriz, la búsqueda y sustitución se realiza en cada una de las entradas de cadena_original y por tanto, el valor devuelto también es una matriz.
Si cadena_buscada y cadena_sustituta son matrices, la función str_replace() selecciona cada vez un valor de ambas matrices y realiza la búsqueda/sustitución. Si cadena_buscada tiene menos elementos que cadena_sustituta , se emplea una cadena vacía para realizar el resto de sustituciones. Si cadena_buscada es una matriz y cadena_sustituta es una cadena, se emplea esta cadena para realizar la sustición de todos los valores de cadena_buscada .
Example #1 Ejemplo de str_replace()
<?php
// Obtiene: <body text='black'>
$etiqueta_body = str_replace("%body%", "black", "<body text='%body%'>");
// Obtiene: Hl Mnd d PHP
$vocales = array("a", "e", "i", "o", "u", "A", "E", "I", "O", "U");
$solo_consonantes = str_replace($vocales, "", "Hola Mundo de PHP");
// Obtiene: Debes comer pizza, cerveza y helados todos los dias
$frase_original = "Debes comer frutas, verduras y fibra todos los dias";
$sano = array("frutas", "verduras", "fibra");
$sabroso = array("pizza", "cerveza", "helados");
$nueva_frase = str_replace($sano, $sabroso, $frase_original);
// El parametro "veces" esta disponible desde la version de PHP 5.0.0
$cadena = str_replace("ll", "", "yo llevaba la llave", $numero_veces);
echo $numero_veces; // El valor de $numero_veces es: 2
?>
Note: Esta función es segura binariamente.
Note: Desde la versión de PHP 5.0.0 el número de cadenas encontradas y sustituidas se devuelve en el parámetro veces , que se pasa por referencia. En las versiones anteriores a PHP 5.0.0, este parámetro no está disponible.

As 'max at efoxdesigns dot com' said, when you try to replace a string that occurs in the $search array after the same character occurs in the $replace character, you don't usually get what you want.
examples:
<?php
$search=array("beer", "graffiti", "programming");
$replace=array("graffiti", "motorcycles", "chips");
$string="I like beer, graffiti and programming.";
var_dump(str_replace($search, $replace, $string));
// you would expect to see:
// string(39) "I like graffiti, motorcycles and chips."
// well.. what you actually see is:
// string(42) "I like motorcycles, motorcycles and chips."
?>
I've made a function (stru_replace) that replaces everything correctly. It has some downsides, as it does not implement all the functionality of str_replace:
<?php
$search=array("beer", "graffiti", "programming");
$replace=array("graffiti", "motorcycles", "chips");
$string="I like beer, graffiti and programming.";
var_dump(str_replace($search, $replace, $string));
//string(39) "I like graffiti, motorcycles and chips."
?>
I'm sure that the functions can be improved. Anyway, I guess they are a bit useful :D
<?php
//returns the key of the minimum value within the array
function minkey($array)
{
$first=true;
$mkey=false;
$mvalue=false;
foreach($array as $key=>$value)
{
if (is_numeric($value))
{
if ($mvalue>$value || $first)
{
$mvalue=$value;
$mkey=$key;
if ($first) $first=false;
}
}
}
return $mkey;
}
//returns the key and the position of the first needle found withing the (string)haystack
function strposfirst($haystack, $needles, $currentpos=0)
{
$positions=array();
foreach($needles as $key=>$value)
$positions[$key]=strpos($haystack,$value,$currentpos);
$minkey=minkey($positions);
if ($minkey===false) return array(false, false);
return array($minkey, $positions[$minkey]);
}
//third parameter must be a string
function stru_replace($search, $replace, $string)
{
$newString="";
// the function only implements functionality for the $search and $replace parameters
// as arrays that have the same ammount of elements
if (is_array($search) && is_array($replace))
{
if (count($search)!=count($replace))
throw new ErrorException("The \$search and \$replace parameters must have the same number of elements");
$oCPos=0; // current position inside old string
$done=false; // determines when we searched all the string
while(!$done)
{
//get the key and position of the first found element
list($key, $position)=strposfirst($string, $search, $oCPos);
//if there is a found element, get concatenate the string before it, and replace the string
if ($position!==false)
{
// the string before the needle is concatenated in the new string
$newString.=substr($string, $oCPos, $position-$oCPos);
// the needle is replaced
$newString.=$replace[$key];
//add the with of the length of the string before the needle + the length of the new key
$oCPos+=$position-$oCPos+strlen($search[$key]);
}
//set the done flag when nothing is found (position is false)
else $done=true;
}
//concatenate the string after the last needle
$newString.=substr($string, $oCPos);
return $newString;
}
else return str_replace($search, $replace, $string);
}
?>
I hope this helps :)

(sorry for pseudo)
here is a function just wrote for my self using str_replace, let me know if there is a better way for such generic function
<?php

$rep_str = "\$sql = str_replace('%$key','$value',\$sql,\$count);";
eval($rep_str);
if($count)
{
$found++;
}
}
if($found == $args_cnt-1)
{
return $sql;
}
else
{
echo "WARNING: number of subs=".($args_cnt-1)." does not match number of reps=$found";

<?php
function str_replace_once($search, $replace, $subject) {
$firstChar = strpos($subject, $search);
if($firstChar !== false) {
$beforeStr = substr($subject,0,$firstChar);
$afterStr = substr($subject, $firstChar + strlen($search));
return $beforeStr.$replace.$afterStr;

If you need to replace áóíóú and other special char, you need encondig type suport.
For this, just use htmlentities and some regular expressions
<?PHP
function RemoveAcentos($str, $enc = "UTF-8"){
$acentos = array(
'A' => '/À|Á|Â|Ã|Ä|Å/',
'a' => '/à|á|â|ã|ä|å/',
'C' => '/Ç/',
'c' => '/ç/',
'E' => '/È|É|Ê|Ë/',
'e' => '/è|é|ê|ë/',
'I' => '/Ì|Í|Î|Ï/',
'i' => '/ì|í|î|ï/',
'N' => '/Ñ/',
'n' => '/ñ/',
'O' => '/Ò|Ó|Ô|Õ|Ö/',
'o' => '/ò|ó|ô|õ|ö/',
'U' => '/Ù|Ú|Û|Ü/',
'u' => '/ù|ú|û|ü/',
'Y' => '/Ý/',
'y' => '/ý|ÿ/',
'a.' => '/ª/',
'o.' => '/º/'

I'm sorry. I can't believe it: I messed up again. Something that I forgot is that the php empty() function considers the number zero (0) as an empty value. Therefore, we need to change our if statement to the following:
<?php
if ($i[0] !== null) $subject .= $replace[$i[0]];
?>
If we left it how it was, the replace ignores the first element of the arrays. ($array[0])
The reason that I used !empty() before, is that I wasn't sure what array_keys() returns if the element is not found (null? and empty string?), since both null and the empty string print out the same and I couldn't find what it returned in this case, in the manual.
The final, working function would look like:
<?php
function str_replace_once($search, $replace, $subject) {
$newArr = str_split($subject);
$subject = '';
foreach ($newArr as $nchar)
{
$i = array_keys($search, $nchar);
if ($i[0] !== null) $subject .= $replace[$i[0]];
else $subject .= $nchar;
}
return $subject;
}
?>

Sorry, folks. That last note I put up won't work quite correctly. Unlike str_replace(), that snippet I showed you will replace any characters that aren't in your $search array with an empty string.
To correct this behavior, add this check to the foreach loop:
<?php
//...
if (!empty($i[0])) $subject .= $replace[$i[0]];
else $subject .= $nchar; //now, if the search character isn't found (ie, we don't care about it), it will stay the same, instead of getting replaced by an empty string.
?>
The whole thing would look like the following, if you were to put it into a function:
<?php
function char_replace_once($search, $replace, $subject) {
$newArr = str_split($subject);
$subject = '';
foreach ($newArr as $nchar)
{
$i = array_keys($search, $nchar);
if (!empty($i[0])) $subject .= $replace[$i[0]];
else $subject .= $nchar;
}
return $subject;
}
?>
I'm sure it may not be as efficient as str_replace(), but it successfully replaces characters, correctly.
ONE OTHER IMPORTANT THING TO NOTE: Unlike I said before, this will only work for character replacement - not string replacement. The reason, of course, is that the original string gets split into an array, who's members are only one character. Sorry about that.
That drawback aside, though, this is still a useful function for doing complete, accurate character replacement.

Note that the str_replace() function is recursive. This is not usually a problem, unless you are trying to do a replace in which a character or string occurs in the $search array, after the same character or string occurs in the $replace array. (For instance, imagine doing a global character replace.)
To demonstrate, take a look at the folowing:
<?php
$search = array('q','w','e','r','t','y','u');
$replace = array('z','s','d','e','y','f','g');
$mystring = 'qwertyu';
//Outputs: zsdeffg
echo str_replace($search, $replace, $mystring);
?>
As you would expect, the q gets replaced by a z, the w by an s, and so on. Everything is correct, except that the t doesn't seem to have been replaced by a y. This is not entirely true, however. What happened is that it did, indeed get replaced by a y, but then on the next pass of the str_replace() function, str_replace() found a y and replaced it with an f.
To get this to work as we'd like (every letter in the $search array replaced by the cooresponding spot in the $replace array), we can do something like the following:
<?php
$search = array('q','w','e','r','t','y','u');
$replace = array('z','s','d','e','y','f','g');
$mystring = 'qwertyu';
//Outputs: zsdeffg (Not what we wanted.)
echo str_replace($search, $replace, $mystring);
$newArr = str_split($mystring); //split $mystring into an array of characters. For php4, you'll have to create the str_split() function.
$newstring = '';
foreach ($newArr as $nchar)
{
$i = array_keys($replace, $nchar); //get the key(s) in the $search array for the character we're replacing. (we assume it occurs only once.) Returns an array of length, 1.
$newstring .= $replace[$i[0]]; //find the character in the $replace array that matches the position of the one we're replacing, and add it to $newstring.
}
//Outputs: zsdeyfg
echo $newstring;
?>
This time, as you can see, there is a y in place of the t, which was what we wanted. :)
Hope that clears up any confusion for anyone wondering why their strings aren't getting replaced as they'd expect.

On the 19th of June, 2008, max at bitsonnet dot com posted a function interpolate that used create_function. I'd never seen create_function before and I thought it was very educational. Thanks, Maxim!
However, the interpolate function can be improved, speed-wise:
<?php
function interpolate2($template, $hash, $prefix = '#{', $postfix = '}')
{
$tmp = array();
foreach($hash as $k => $v)
{
$tmp[$prefix . $k . $postfix] = $v;
}
return str_replace(array_keys($tmp), array_values($tmp), $template);
}
echo interpolate2('Hello, #{username}. Welcome to #{site}.', array('username' => 'World', 'site' => 'php.net'));
?>
According to my own tests, this version is somewhere between 4 and 5 times faster.
Note, btw, that I used a very similar function on the sprintf page.

I always miss interpolate functionality in PHP, so I wrote this little helper method. It allows you to specify your own markup using $prefix and $postfix.
<?php
# Interpolate a string using hash.
# by Maxim Chernyak ( http://mediumexposure.com )
function interpolate($template, $hash, $prefix = '#{', $postfix = '}' ) {
$tokenize = create_function('$token', 'return "'. $prefix .'".$token."'.$postfix.'";');
$keys = array_keys($hash);
$values = array_values($hash);
$keys = array_map($tokenize, $keys);
return str_replace($keys, $values, $template);
}
?>
For example:
<?php
$result = interpolate('Hello, #{username}. Welcome to #{site}.', array('username' => 'Hakunin', 'site' => 'php.net'));
?>

The example presented by bladescope at googlemail dot com has a couple of syntax errors. This works:
<?php
$template = "The {color} {object} is in {location}";
$array = array(
'{object}' => 'Ball',
'{color}' => 'Red',
'{location}' => 'The Playground',
);
foreach ($array as $search => $replace) {
$template = str_replace($search, $replace, $template);
}
print $template;
?>
I did not check it for speed or thoroughly test it, but this function seems to do the same thing more succinctly.
<?php
function template($array, $template) {
return str_replace(
array_keys($array),
array_values($array),
$template
);
}
echo template(
array(
'{color}' => 'red',
'{object}' => 'ball',
'{location}' => 'the playground',
),
'The {color} {object} is in {location}.'
);

This is the functions I wrote for the problem reported above, str_replace in multi-dimensional arrays. It can work with preg_replace as well.

if (is_array($INPUT) and count($INPUT)<>count($INPUT,1)):
foreach($INPUT as $FAN):
$OUTPUT[]=array_replace($SEARCH,$REPLACE,$FAN);
endforeach;
else:
$OUTPUT=str_replace($SEARCH,$REPLACE,$INPUT);
endif;
return $OUTPUT;
}

With PHP 4.3.1, at least, str_replace works fine when working with single arrays but mess it all with two or more dimension arrays.
<?php
$subject = array("You should eat this","this","and this every day.");
$search = "this";
$replace = "that";
$new = str_replace($search, $replace, $subject);
print_r($new); // Array ( [0] => You should eat that [1] => that [2] => and that every day. )

In order to replace carriage return characters from form inputs, if everything else fails, you can try:
<?php
$new_text = str_replace(chr(13).chr(10), '_', $original_text);
?>
And in order to show the line feeds in a javascript alert, you can do:
<?php
$new_text = str_replace(chr(13).chr(10), '\n', $original_text);
?>

Here is a version that allows for empty multidimensional arrays:
<?php
function str_replace_array ($search, $replace, $subject) {
if (is_array($subject)) {
foreach ($subject as $id=>$inner_subject) {
$subject[$id]=str_replace_array($search, $replace, $inner_subject);
}
} else {
$subject=str_replace($search, $replace, $subject);
}
return $subject;
}
?>

I found that having UTF-8 strings in as argument didnt
work for me using heavyraptors function.
Adding UTF-8 as argument on htmlentities
fixed the problem.
cheers, tim at hysniu.com
<?php
function replace_accents($str) {
$str = htmlentities($str, ENT_COMPAT, "UTF-8");
$str = preg_replace(
'/&([a-zA-Z])(uml|acute|grave|circ|tilde);/',
'$1',$str);
return html_entity_decode($str);
}
?>

My input is MS Excel file but I want to save ‘,’,“,” as ',',",".
$badchr = array(
"\xc2", // prefix 1
"\x80", // prefix 2
"\x98", // single quote opening
"\x99", // single quote closing
"\x8c", // double quote opening
"\x9d" // double quote closing
);
$goodchr = array('', '', '\'', '\'', '"', '"');
str_replace($badchr, $goodchr, $strFromExcelFile);
Works for me.

This is a more rigid alternative to spectrereturns at creaturestoke dot com's replace_different function:
<?php
function str_replace_many ($search, $replacements, $subject) {
$index = strlen($subject);
$replacements = array_reverse($replacements);
if (count($replacements) != substr_count($subject, $search)) {
return FALSE;
}
foreach ($replacements as $replacement) {
$index = strrpos(substr($subject, 0, $index), $search);
$prefix = substr($subject, 0, $index);
$suffix = substr($subject, $index + 1);
$subject = $prefix . $replacement . $suffix;
}
return $subject;
}
?>
This will return false if there are a different number of $replacements versus number of occurrences of $search in $subject. Additionally, $search much be exactly one character (if a string is provided, only the first character in the string will be used). Examples:
<?php
echo str_replace_many('?',array('Jane','banana'),'? is eating a ?.');
?>
prints: "Jane is eating a banana."

Before spending hours searching your application why it makes UTF-8 encoding into some malformed something with str_replace, make sure you save your PHP file in UTF-8 (NO BOM).
This was at least one of my problems.

I create a little function to transform (to example) "User@example.net" in "user AT example DOT net" and conversely.
<?php
function code_mail($email) {
if(preg_match('`^.+@.+\..{1,5}$`', $email)) { //email format
$email = str_replace('.', ' DOT ', $email); //replace . by dot
$email = str_replace('@', ' AT ', $email); //replace @ by at
return $email;
}
else { //not email format
return false;
}
}
function decode_mail($email) { //on décode...
$email = str_replace(' DOT ', '.',
