ok, I gave it a try and honestly this is probably over my head :) but here is something to try <?php $url='http://www.textx.com/t1/t2/t3/blah.html'; function ret_url($rel_path, $base = '') { $base_path = substr($base, 0, strpos($base, '/',7)); if(substr($rel_path,0,1)=='/' && strpos($rel_path,'/../') === false) { return $base_path.$rel_path; } elseif(strpos($rel_path,'://') > 0) { return $rel_path; } else { return collapse(dirname($base),$rel_path); } return $rel_path; } /* this function removes the /../ parts */ function collapse($path,$rel_path) { $parsed = parse_url($path); preg_match_all('/\/\.\./',$rel_path, $matches); if(($count = count($matches[0])) > 0) { $parts = preg_split('/\//', $parsed['path'], -1, PREG_SPLIT_NO_EMPTY); for ($i = 1;$i <= $count; $i++) { array_pop($parts); } $path = str_replace($parsed['path'], '/'.implode($parts,'/'), $path); } $rel_path = (preg_match('/^\//',$rel_path)) ? $rel_path :'/'.$rel_path; $path = preg_replace('/\/\.\./', '', $path.$rel_path); return $path; } $uris = array(); $uris[] = '/blah.jpg'; $uris[] ='/imgs/blah.jpg'; $uris[] ='imgs/blah.jpg'; $uris[] ='../imgs/blah.jpg'; $uris[] ='/../imgs/blah.jpg'; // ## not working ## $uris[] ='/../../imgs/test.jpg'; // ## not working ## $uris[] ='http://some-site-blah.com/imgs/blah.jpg'; echo '<table border=1>'; foreach($uris as $uri) { echo '<tr><td>'.htmlspecialchars($uri).'</ td><td>'.htmlspecialchars(ret_url($uri,$url)).'</td></tr>'; } echo '</table>'; ?> -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
