note 76979 added to function.parse-url

In reply to adrian, Thank you very much for your function. There is a small issue with your relative protocol function. You need to remove the // when making the url the path. Here is the new function. function resolve_url($base, $url) { if (!strlen($base)) return $url; // Step 2 if (!strlen($url)) return $base; // Step 3 if (preg_match('!^[a-z]+:!i', $url)) return $url; $base = parse_url($base); if ($url{0} == "#") { // Step 2 (fragment) $base['fragment'] = substr($url, 1); return unparse_url($base); } unset($base['fragment']); unset($base['query']); if (substr($url, 0, 2) == "//") { // Step 4 return unparse_url(array( 'scheme'=>$base['scheme'], 'path'=>substr($url,2), )); } else if ($url{0} == "/") { // Step 5 $base['path'] = $url; } else { // Step 6 $path = explode('/', $base['path']); $url_path = explode('/', $url); // Step 6a: drop file from base array_pop($path); // Step 6b, 6c, 6e: append url while removing "." and ".." from // the directory portion $end = array_pop($url_path); foreach ($url_path as $segment) { if ($segment == '.') { // skip } else if ($segment == '..' && $path && $path[sizeof($path)-1] != '..') { array_pop($path); } else { $path[] = $segment; } } // Step 6d, 6f: remove "." and ".." from file portion if ($end == '.') { $path[] = ''; } else if ($end == '..' && $path && $path[sizeof($path)-1] != '..') { $path[sizeof($path)-1] = ''; } else { $path[] = $end; } // Step 6h $base['path'] = join('/', $path); } // Step 7 return unparse_url($base); } ---- Server IP: 208.69.120.35 Probable Submitter: 207.126.230.225 ---- Manual Page -- http://www.php.net/manual/en/function.parse-url.php Edit -- https://master.php.net/note/edit/76979 Del: integrated -- https://master.php.net/note/delete/76979/integrated Del: useless -- https://master.php.net/note/delete/76979/useless Del: bad code -- https://master.php.net/note/delete/76979/bad+code Del: spam -- https://master.php.net/note/delete/76979/spam Del: non-english -- https://master.php.net/note/delete/76979/non-english Del: in docs -- https://master.php.net/note/delete/76979/in+docs Del: other reasons-- https://master.php.net/note/delete/76979 Reject -- https://master.php.net/note/reject/76979 Search -- https://master.php.net/manage/user-notes.php
