note 75140 added to function.preg-match

Here's a function that will return a proper formated URL. As WWW is deprecated, it strips away any attempt of WWW in the URL. <?php // // Proper URL function // by Christian Meinhold - loathsome.us // function proper_url($input){ // check if it's a proper formed URL if(preg_match("/^(.*)\.(.*)$/", $input)){ if(!preg_match("/^http:\/\/(.*)$/", $input)){ $result = 'http://' . $input; } else { $result = $input; } // www is deprecated if(preg_match("/http:\/\/www\./i", $result)){ $result = str_ireplace('www.', '', $result); } } else { return false; } // return final string return $result; } # END FUNCTION $url = 'www.bullshit.loathsome.us'; // http://bullshit.loathsome.us echo (proper_url($url) ? proper_url($url) : 'Invalid URL'); ?> ---- Server IP: 128.39.198.38 Probable Submitter: 84.48.75.189 ---- Manual Page -- http://www.php.net/manual/en/function.preg-match.php Edit -- https://master.php.net/note/edit/75140 Del: integrated -- https://master.php.net/note/delete/75140/integrated Del: useless -- https://master.php.net/note/delete/75140/useless Del: bad code -- https://master.php.net/note/delete/75140/bad+code Del: spam -- https://master.php.net/note/delete/75140/spam Del: non-english -- https://master.php.net/note/delete/75140/non-english Del: in docs -- https://master.php.net/note/delete/75140/in+docs Del: other reasons-- https://master.php.net/note/delete/75140 Reject -- https://master.php.net/note/reject/75140 Search -- https://master.php.net/manage/user-notes.php
