As far as recursive copy, something like this seems to work fine for me:
<?php
$output = shell_exec( " cp -r -a dir_source/* dir_dest 2>&1 " )
echo $output
?>
Of course you need to get all your permissions clear. You can do the necessary stuff to use variables.
You could also do this to create the destination directory:
<?php
shell_exec( " cp -r -a dir_source dir_dest 2>&1 " )
?>
This will create a new directory called "dir_dest" if it does not already exist. This is a bit risky though if your situation is ambiguous, and you want to continue to make backups etc, 'cause if you do it twice you end up with:
dir_destination/dir_source
to avoid that one could do something like:
<?php
shell_exec( " mkdir dir_dest; cp -r -a dir_source/* dir_dest 2>&1 " )
?>
Maybe someone can tell me when or why it would be better to use all that PHP code I see here.
copy
(PHP 4, PHP 5)
copy — Copies file
Description
bool copy
( string $source
, string $dest
[, resource $context
] )
Makes a copy of the file source to dest .
If you wish to move a file, use the rename() function.
Parameters
- source
-
Path to the source file.
- dest
-
The destination path. If dest is a URL, the copy operation may fail if the wrapper does not support overwriting of existing files.
WarningIf the destination file already exists, it will be overwritten.
- context
-
A valid context resource created with stream_context_create().
Return Values
Returns TRUE on success or FALSE on failure.
Changelog
| Version | Description |
|---|---|
| 5.3.0 | Added context support. |
| 4.3.0 | Both source and dest may now be URLs if the "fopen wrappers" have been enabled. See fopen() for more details. |
Examples
Example #1 copy() example
<?php
$file = 'example.txt';
$newfile = 'example.txt.bak';
if (!copy($file, $newfile)) {
echo "failed to copy $file...\n";
}
?>

Thanks SkyEye for a wonderful copy program that I can work with. Being a info-lover, I've changed your datacopy() a bit. I've added more information than just the number of files copied. It now shows Number of files, number of failed files, total amount of data copied (in bytes, i think), and the path to the failed files. It could probably be cleaned up a little, but I'm too lazy to do so, as it is very efficient right now.

On Windows (not sure about Linux) copy will overwrite an existing file but will not change the case of the existing filename.
In other words if I have a file named "Myfile.txt" and I overwrite it using copy with a file named "MyFile.txt" it will overwrite it but the filename will remain "Myfile.txt".
If this is a problem (as it was for me) use unlink to delete the existing file first.

Don't forget; you can use copy on remote files, rather than doing messy fopen stuff. e.g.
<?php
if(!@copy('http://someserver.com/somefile.zip','./somefile.zip'))
{
$errors= error_get_last();
echo "COPY ERROR: ".$errors['type'];
echo "<br />\n".$errors['message'];
} else {
echo "File copied from remote!";
}

It's worth noting that copy() sets the destination file's last modified time/date.

Here's another recursive copy function. Unlike the others this one relies on the built-in dir class and is thus much cleaner and simpler.
<?php
function full_copy( $source, $target )
{
if ( is_dir( $source ) )
{
@mkdir( $target );
$d = dir( $source );
while ( FALSE !== ( $entry = $d->read() ) )
{
if ( $entry == '.' || $entry == '..' )
{
continue;
}
$Entry = $source . '/' . $entry;
if ( is_dir( $Entry ) )
{
full_copy( $Entry, $target . '/' . $entry );
continue;
}
copy( $Entry, $target . '/' . $entry );
}
$d->close();
}else
{
copy( $source, $target );
}
}

It seems as though you can only use move_uploaded_file() once on a temporary file that has been uploaded through a form. Most likely the action this function takes destroys the temporary file after it has been moved, assuming permanent placement on a file system.
Attempting to use the function again in the same PHP script will return false and not move the file.
I ran into this when an image that was uploaded did not need resizing (smaller than a size threshold) and after moving the temporary upload to the "originals" directory, an attempt was made to again move the temporary file to another folder.
This behavior is understandable, but be careful - in this instance, I simply used copy() on the file that was already uploaded.

This function creates a new filename to use for a copy of the given filename, its behaviour was mostly sto^Wborrowed from how the OS X Finder (*1) does it.
Note it *doesn't* actually copy the file, it just returns the new name. I needed it to work regardless of data source (filesystem, ftp, etc).
It also tries to match the current name as neatly as possible:
foo.txt -> foo copy.txt -> foo copy 1.txt -> foo copy 2.txt [etc]
foo.bar.baz.jpg -> foo.bar.baz copy.jpg
foobar -> foobar copy -> foobar copy 1 [etc]
".txt" -> .txt copy, and "txt." -> txt. copy
file.longextension -> file.longextension copy
It keeps trying until it finds a name that is not yet taken in $list, or until it looped 500 times (change as needed).
If the renamed file becomes longer than max filename length, it starts chopping away at the end of the part before where it adds " copy": reallylong...filename.txt -> reallylong...filena copy.txt
<?php
// $orig = current name, of course
// $list = array of filenames in the target directory (if none given, it will still return a new name)
// $max = max length of filename

$ext = '';
$counter = 0;
$list = (array) $list;
$max = (int) $max;

$name = $newname; # name in, newname out

// preg hereunder matches anything with at least one period in the middle (that is,

*1) The Finder seems to check the extension vs a list of known extensions, this function considers it valid if it's 5 or fewer characters long.
ps. sorry for taking up so much space! :-)

To use the previous function on UNIX systems you should change these lines:
$srcfile = $srcdir . '\\' . $file;
$dstfile = $dstdir . '\\' . $file;
To match the following:
$srcfile = $srcdir . DIRECTORY_SEPARATOR . $file;
$dstfile = $dstdir . DIRECTORY_SEPARATOR . $file;

Just some caveats for people to consider when working with this copy function. Like everyone else, I needed a recursive copy function, so I wrote one.
It worked great until I hit a file greater than 2GB, at which point I got a File Size Exceeded error. I've read that you can recompile PHP with larger file support, but I'm not able to do this on my system.
So I used exec to copy one file at a time (I need to do other things to the file, so can't just do an exec with "cp -r"). Then I ran into problems with spaces in the names. The escapeshellcmd and escapeshellargs functions don't seem to cleanup spaces, so I wrote my own function to do that.

You can also try to copy with:
<?
exec("cp -r /var/www/mysite /var/backup");
?>

to the editor's: Please pardon me.... remove my other 2 messages and this little comment and just stick this.
just a quick note to add to the great function by:bobbfwed at comcast dot net
this little version has the path not in a define but as a function parameter and also creates the destination directory if it is not already created.
<?php
// copy a directory and all subdirectories and files (recursive)
// void dircpy( str 'source directory', str 'destination directory' [, bool 'overwrite existing files'] )
function dircpy($basePath, $source, $dest, $overwrite = false){
if(!is_dir($basePath . $dest)) //Lets just make sure our new folder is already created. Alright so its not efficient to check each time... bite me
mkdir($basePath . $dest);
if($handle = opendir($basePath . $source)){ // if the folder exploration is sucsessful, continue
while(false !== ($file = readdir($handle))){ // as long as storing the next file to $file is successful, continue
if($file != '.' && $file != '..'){
$path = $source . '/' . $file;
if(is_file($basePath . $path)){
if(!is_file($basePath . $dest . '/' . $file) || $overwrite)
if(!@copy($basePath . $path, $basePath . $dest . '/' . $file)){
echo '<font color="red">File ('.$path.') could not be copied, likely a permissions problem.</font>';
}
} elseif(is_dir($basePath . $path)){
if(!is_dir($basePath . $dest . '/' . $file))
mkdir($basePath . $dest . '/' . $file); // make subdirectory before subdirectory is copied
dircpy($basePath, $path, $dest . '/' . $file, $overwrite); //recurse!
}
}
}
closedir($handle);
}
}

I have been puzzling for hours with the copy() function. I got a "no such file or directory" error message all the time (for the source file). In the end my mistake was that there were some spaces at the end of de source filename...
So, if you get file not found errors and you are sure that the file does exists, use the trim() function to get rid of the spaces.

It take me a long time to find out what the problem is when i've got an error on copy(). It DOESN'T create any directories. It only copies to existing path. So create directories before. Hope i'll help,

I have programmed a really nice program that remotely lets you manage files as if you have direct access to them (http://sourceforge.net/projects/filemanage/). I have a bunch of really handy functions to do just about anything to files or directories.
I know there are others like it, but here is the function I made for this program to copy directories; it will likely need tweaking to work as a standalone script, since it relies of variables set by my program (eg: loc1 -- which dynamically changes in my program):
<?PHP
// loc1 is the path on the computer to the base directory that may be moved
define('loc1', 'C:/Program Files/Apache Group/Apache/htdocs', true);
// copy a directory and all subdirectories and files (recursive)
// void dircpy( str 'source directory', str 'destination directory' [, bool 'overwrite existing files'] )
function dircpy($source, $dest, $overwrite = false){
if($handle = opendir(loc1 . $source)){ // if the folder exploration is sucsessful, continue
while(false !== ($file = readdir($handle))){
