The first argument to copy() function cannot be a directory? - php

Question

$base = dirname(__FILE__).'/themes/';
$target = dirname( STYLESHEETPATH ).'/';
$directory_folders = new DirectoryIterator($base);
foreach ($directory_folders as $folder)
{
if (!$folder->isDot()) {
echo '<p>source: '.$folder->getRealPath();
//returns: C:\xampplite\htdocs\test\wp-content\plugins\test\themes\testtheme-1
echo '<br>target: '.$target;
//returns: C:\xampplite\htdocs\test/wp-content/themes/
copy($folder->getRealPath(), $target);
//returns: Error. The first argument to copy() function cannot be a directory
}
}die;
UPDATE: On Pascal's suggested answer, here's my amended code. This works.
function recurse_copy(){
$src = dirname(__FILE__).'/themes/';
$dst = dirname( STYLESHEETPATH ).'/';
$dir = opendir($src);
#mkdir($dst);
while(false !== ( $file = readdir($dir)) )
{
if (( $file != '.' ) && ( $file != '..' ))
{
if ( is_dir($src . '/' . $file) ) {
recurse_copy_recurse($src . '/' . $file,$dst . '/' . $file);
}
else {
copy($src . '/' . $file,$dst . '/' . $file);
}
}
}
closedir($dir);
}
function recurse_copy_recurse($src,$dst){
$dir = opendir($src);
#mkdir($dst);
while(false !== ( $file = readdir($dir)) )
{
if (( $file != '.' ) && ( $file != '..' ))
{
if ( is_dir($src . '/' . $file) ) {
recurse_copy_recurse($src . '/' . $file,$dst . '/' . $file);
}
else {
copy($src . '/' . $file,$dst . '/' . $file);
}
}
}
closedir($dir);
}

No, the copy() function is not recursive : it cannot copy folders and their contents.
But if you take a look at the users's notes on that manual page, you'll find some propositions of recursive implementations.
For example, here's a recursive function proposed by gimmicklessgpt (quoting his post) :
<?php
function recurse_copy($src,$dst) {
$dir = opendir($src);
#mkdir($dst);
while(false !== ( $file = readdir($dir)) ) {
if (( $file != '.' ) && ( $file != '..' )) {
if ( is_dir($src . '/' . $file) ) {
recurse_copy($src . '/' . $file,$dst . '/' . $file);
}
else {
copy($src . '/' . $file,$dst . '/' . $file);
}
}
}
closedir($dir);
}
?>
Edit after the edit of the question :
You are calling your function passing it parameters :
recurse_copy($src . '/' . $file,$dst . '/' . $file);
But your function is defined as taking no parameter :
function recurse_copy(){
$src = dirname(__FILE__).'/themes/';
$dst = dirname( STYLESHEETPATH ).'/';
...
You should correct your function's definition, so it takes parameters -- and not initialize those $src and $dst inside the function, but on its first call.
