PHP: making a file executable

The following little code snippet shows you how to change a files permissions to allow its owning user and group to read and execute it.

public function makeExecutable() {
	if(file_exists($this->executablePath)) {
		if(DIRECTORY_SEPARATOR == '/') {
			// add executable (1) and read (4) bits for user and group
			$filePermissions = decoct(fileperms($this->executablePath));
			$filePermissions = substr($filePermissions, strlen($filePermissions) - 3);
			$newFilePermissions = $filePermissions[0] | 5;
			$newFilePermissions .= $filePermissions[1] | 5;
			$newFilePermissions .= $filePermissions[2];
			if($newFilePermissions != $filePermissions) {
				return chmod($this->executablePath, octdec($newFilePermissions));
			}
		}
	}
	return false;
}
