note 95901 added to function.file-exists

Just to take further joel atSymbol avial.com.au's routine, I had a need for a case-insensitive file_exists that would cope with the directory names also being wrongly cased. This recursive version does the trick. It also returns the actual filename as it exists on the disc, or an empty string, so that subsequent operations can locate the file. function similar_file_exists($filename) { if ($filename == "") return ""; if (file_exists($filename)) { return $filename; } $dir = dirname($filename); if (!file_exists($dir)) { if (($dir=similar_file_exists($dir)) == "") return ""; } $files = glob($dir . '/*'); $lcaseFilename = strtolower($filename); foreach($files as $file) { if (strtolower($file) == $lcaseFilename) { return $file; } } return ""; } ---- Server IP: 69.147.83.197 Probable Submitter: 87.81.12.15 ---- Manual Page -- http://www.php.net/manual/en/function.file-exists.php Edit -- https://master.php.net/note/edit/95901 Del: integrated -- https://master.php.net/note/delete/95901/integrated Del: useless -- https://master.php.net/note/delete/95901/useless Del: bad code -- https://master.php.net/note/delete/95901/bad+code Del: spam -- https://master.php.net/note/delete/95901/spam Del: non-english -- https://master.php.net/note/delete/95901/non-english Del: in docs -- https://master.php.net/note/delete/95901/in+docs Del: other reasons-- https://master.php.net/note/delete/95901 Reject -- https://master.php.net/note/reject/95901 Search -- https://master.php.net/manage/user-notes.php
