note 75409 added to function.realpath

I have also a short solution. But Im not sure, if it is performant. Explode-Array solution seems to work very fast. function buildRelativePath($path){ $oldP = ""; $newP = $path; while($newP!=$oldP){ $oldP = $newP; $newP = preg_replace("/([^\/]+\/)([^\/]+\/)(\.\.\/)/ms","$1",$newP); } return str_replace("//","",str_replace("./","",$newP)); } ---- Server IP: 217.160.72.57 Probable Submitter: 84.58.245.161 ---- Manual Page -- http://www.php.net/manual/en/function.realpath.php Edit -- https://master.php.net/note/edit/75409 Del: integrated -- https://master.php.net/note/delete/75409/integrated Del: useless -- https://master.php.net/note/delete/75409/useless Del: bad code -- https://master.php.net/note/delete/75409/bad+code Del: spam -- https://master.php.net/note/delete/75409/spam Del: non-english -- https://master.php.net/note/delete/75409/non-english Del: in docs -- https://master.php.net/note/delete/75409/in+docs Del: other reasons-- https://master.php.net/note/delete/75409 Reject -- https://master.php.net/note/reject/75409 Search -- https://master.php.net/manage/user-notes.php
