I was looking for a quick code example on recursively moving files with PHP and I only saw code snippets using PHP 5. I like using the new and powerful features of PHP 5 when doing file system interactions so I wrote two quick PHP 5 functions that will move or copy directories and files recursively. That means your entire file tree will be moved or copied. The following is the code you can use for reference with your own recursive move or copy functions.

Move

/**
 * Recursively move files from one directory to another
 * 
 * @param String $src - Source of files being moved
 * @param String $dest - Destination of files being moved
 */
function rmove($src, $dest){

    // If source is not a directory stop processing
    if(!is_dir($src)) return false;

    // If the destination directory does not exist create it
    if(!is_dir($dest)) { 
        if(!mkdir($dest)) {
            // If the destination directory could not be created stop processing
            return false;
        }    
    }

    // Open the source directory to read in files
    $i = new DirectoryIterator($src);
    foreach($i as $f) {
        if($f->isFile()) {
            rename($f->getRealPath(), "$dest/" . $f->getFilename());
        } else if(!$f->isDot() && $f->isDir()) {
            rmove($f->getRealPath(), "$dest/$f");
            unlink($f->getRealPath());
        }
    }
    unlink($src);
}

Copy

/**
 * Recursively copy files from one directory to another
 * 
 * @param String $src - Source of files being moved
 * @param String $dest - Destination of files being moved
 */
function rcopy($src, $dest){

    // If source is not a directory stop processing
    if(!is_dir($src)) return false;

    // If the destination directory does not exist create it
    if(!is_dir($dest)) { 
        if(!mkdir($dest)) {
            // If the destination directory could not be created stop processing
            return false;
        }    
    }

    // Open the source directory to read in files
    $i = new DirectoryIterator($src);
    foreach($i as $f) {
        if($f->isFile()) {
            copy($f->getRealPath(), "$dest/" . $f->getFilename());
        } else if(!$f->isDot() && $f->isDir()) {
            rcopy($f->getRealPath(), "$dest/$f");
        }
    }
}

Deploying with the Cloud 9 IDE

(Updated: Nov 2, 2012)

Stephen Owens wrote up a great intro to using the Cloud 9 IDE to build on a development environment and utilize a modified version of the above code to then migrate to the production server. See his comment below for details.
