Source Body

public static function find($paths, $file)
{
        settype($paths, 'array'); //force to array

        // start looping through the path set
        foreach ($paths as $path)

                // get the path to the file
                $fullname = $path.DS.$file;

                // is the path based on a stream?

                {
                        // not a stream, so do a realpath() to avoid directory
                        // traversal attempts on the local file system.
                        $path = realpath($path); // needed for substr() later
                        $fullname = realpath($fullname);

                // the substr() check added to make sure that the realpath()
                // results in a directory registered so that
                // non-registered directores are not accessible via directory
                // traversal attempts.
                if (file_exists($fullname) && substr($fullname, 0, strlen($path)) == $path) {
