Creating a zip archive with php

[Adem]

Hello,

The following code creates a zip archive with the complete file
But it adds reverse slash at the beginning of the files
What adds this backslash?

$zip = new ZipArchive();
if ($zip->open($destination, ZIPARCHIVE::CREATE)) {
	$source = realpath($source);
	global $zipyorumadizinadi;
	$zip->setArchiveComment($zipyorumadizinadi);
	if (is_dir($source)) {
		$iterator = new RecursiveDirectoryIterator($source);

		$iterator->setFlags(RecursiveDirectoryIterator::SKIP_DOTS);
		$files = new RecursiveIteratorIterator($iterator, RecursiveIteratorIterator::SELF_FIRST);

		foreach ($files as $file) {
			$file = realpath($file);
			if (is_dir($file)) {
				$zip->addEmptyDir(str_replace($source . '', '', $file . ''));
			} else if (is_file($file)) {
				$zip->addFromString(str_replace($source . '', '', $file), file_get_contents($file));
			}
		}
	} else if (is_file($source)) {
		$zip->addFromString(basename($source), file_get_contents($source));
	}
}
