Recursive Copy of Directory

Question

On my old VPS I was using the following code to copy the files and directories within a directory to a new directory that was created after the user submitted their form.

Answer 1

function recurse_copy($source, $dest)
{
    // Check for symlinks
    if (is_link($source)) {
        return symlink(readlink($source), $dest);
    }

    // Simple copy for a file
    if (is_file($source)) {
        return copy($source, $dest);
    }

    // Make destination directory
    if (!is_dir($dest)) {
        mkdir($dest);
    }

    // Loop through the folder
    $dir = dir($source);
    while (false !== $entry = $dir->read()) {
        // Skip pointers
        if ($entry == '.' || $entry == '..') {
            continue;
        }

        // Deep copy directories
        recurse_copy("$source/$entry", "$dest/$entry");
    }

    // Clean up
    $dir->close();
    return true;
}

Answer 2

hmm. as that's complicated ))

function mkdir_recursive( $dir ){
  $prev = dirname($dir);
  if( ! file_exists($prev))
  {
    mkdir_recursive($prev);
  }
  if( ! file_exists($dir))
  {
     mkdir($dir);
  }
}

...

foreach( $files as $file){
  mkdir_recursive( dirname( $dir_d . $file));
  copy( $dir_s . $file, $dir_d . $file);
}

$file - somthing like that www/folder/ahah/file.txt

There were some issues with the functions that I tested in the thread and here is a powerful function that covers everything. Highlights:

1. No need to have an initial or intermediate source directories. All of the directories up to the source directory and to the copied directories will be handled.

2. Ability to skip directory or files from an array. (optional) With the global $skip; skipping of files even under sub level directories are handled.

3. Full recursive support, all the files and directories in multiple depth are supported.

$from = "/path/to/source_dir";
$to = "/path/to/destination_dir";
$skip = array('some_file.php', 'somedir');

copy_r($from, $to, $skip);

function copy_r($from, $to, $skip=false) {
    global $skip;
    $dir = opendir($from);
    if (!file_exists($to)) {mkdir ($to, 0775, true);}
    while (false !== ($file = readdir($dir))) {
        if ($file == '.' OR $file == '..' OR in_array($file, $skip)) {continue;}
        
        if (is_dir($from . DIRECTORY_SEPARATOR . $file)) {
            copy_r($from . DIRECTORY_SEPARATOR . $file, $to . DIRECTORY_SEPARATOR . $file);
        }
        else {
            copy($from . DIRECTORY_SEPARATOR . $file, $to . DIRECTORY_SEPARATOR . $file);
        }
    }
    closedir($dir);
}

Here's what we use at our company:

static public function copyr($source, $dest)
{
    // recursive function to copy
    // all subdirectories and contents:
    if(is_dir($source)) {
        $dir_handle=opendir($source);
        $sourcefolder = basename($source);
        mkdir($dest."/".$sourcefolder);
        while($file=readdir($dir_handle)){
            if($file!="." && $file!=".."){
                if(is_dir($source."/".$file)){
                    self::copyr($source."/".$file, $dest."/".$sourcefolder);
                } else {
                    copy($source."/".$file, $dest."/".$file);
                }
            }
        }
        closedir($dir_handle);
    } else {
        // can also handle simple copy commands
        copy($source, $dest);
    }
}

Answer 5

OzzyCheck's is elegant and original, but he forgot the initial mkdir($dest); See below. No copy command is ever provided with contents only. It must fulfill its entire role.

$source = "dir/dir/dir";
$dest= "dest/dir";

mkdir($dest, 0755);
foreach (
  $iterator = new RecursiveIteratorIterator(
  new RecursiveDirectoryIterator($source, RecursiveDirectoryIterator::SKIP_DOTS),
  RecursiveIteratorIterator::SELF_FIRST) as $item) {
  if ($item->isDir()) {
    mkdir($dest . DIRECTORY_SEPARATOR . $iterator->getSubPathName());
  } else {
    copy($item, $dest . DIRECTORY_SEPARATOR . $iterator->getSubPathName());
  }
}

Here's a simple recursive function to copy entire directories

source: http://php.net/manual/de/function.copy.php

<?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); 
} 
?>
