note 116839 added to function.rawurlencode

For those looking to strip all non-reserved characters from a URL according to RFC 3986, the code would look like: <?php $stripped = preg_replace('/[^[:alnum:]-._~]/', '', $source); ?> To get this string as it should be used in a url, you still probably want to use rawurlencode, as the [:alpha:] posix bracket expression will catch accented characters - use [A-Za-z][0-9] instead if you only want to include ascii characters. So a basic "slug" generation routine might look like: <?php function strtoslug($string) { // strip out all but unreserved characters from rfc:3986 $stripped = preg_replace('/[^[:alnum:][:blank:]-._~]/', '', $string); // convert compacted whitespace to hyphens $slug = preg_replace('/[:blank:]+/', '-', $stripped); return $slug; } ?> ---- Server IP: 72.52.91.14 Probable Submitter: 173.166.142.162 ---- Manual Page -- http://php.net/manual/en/function.rawurlencode.php Edit -- https://master.php.net/note/edit/116839 Del: integrated -- https://master.php.net/note/delete/116839/integrated Del: useless -- https://master.php.net/note/delete/116839/useless Del: bad code -- https://master.php.net/note/delete/116839/bad+code Del: spam -- https://master.php.net/note/delete/116839/spam Del: non-english -- https://master.php.net/note/delete/116839/non-english Del: in docs -- https://master.php.net/note/delete/116839/in+docs Del: other reasons-- https://master.php.net/note/delete/116839 Reject -- https://master.php.net/note/reject/116839 Search -- https://master.php.net/manage/user-notes.php
