<?php
$source = '/var/www/html/pranav_test/';
$destination = '/var/www/html/parth/';
$sourceFiles = glob($source . '*');
foreach($sourceFiles as $file) {
   $baseFile = basename($file);
    if (file_exists($destination . $baseFile)) {
        $originalHash = md5_file($file);
        $destinationHash = md5_file($destination . $baseFile);
        if ($originalHash === $destinationHash) {
            continue;
        }
    }
    copy($file, $destination . $baseFile);
}
