php从一个文件夹复制到另一个文件夹的功能

<?php
function copyFolder($source, $destination) {
    if (!file_exists($destination)) {
        mkdir($destination, 0777, true);
    }
    
    $dir = opendir($source);
    while (false !== ($file = readdir($dir))) {
        if (($file != '.') && ($file != '..')) {
            $sourceFile = $source . '/' . $file;
            $destinationFile = $destination . '/' . $file;
            
            if (is_dir($sourceFile)) {
                copyFolder($sourceFile, $destinationFile);
            } else {
                copy($sourceFile, $destinationFile);
            }
        }
    }
    closedir($dir);
}

$sourceFolder = '/path/to/source/folder';
$destinationFolder = '/path/to/destination/folder';

copyFolder($sourceFolder, $destinationFolder);
?>
