note 64114 added to function.scandir

I would like to share a couple of functions I've made to get an Array of files of a certain extension inside a Directory. <?php // Firstly, a PHP 5 emulation function php4_scandir($dir, $sort = 0) { if (PHP_VERSION >= '5') return scandir($dir, $sort); $dirmap = array(); if(!is_dir($dir)) { trigger_error("lib::scandir($dir): failed to open dir: Invalid argument", E_USER_WARNING); return false; } $dir = opendir($dir); while (false !== ($file = readdir($dir))) $dirmap[] = $file; closedir($dir); ($sort == 1) ? rsort($dirmap) : sort($dirmap); return $dirmap; } /* Then, this one converts directory files into array items. It also can filter by file extension. */ function dir2arr($dir, $ext = null) { $arr = array(); if(PHP_VERSION >= '4.3.0') { # PHP 4.3.0 code if ($dir = glob("$dir*".(!$ext ? '.*' : '{'.$ext.', '.strtoupper($ext).'}'), GLOB_NOSORT + GLOB_BRACE)) foreach ($dir as $file) $arr[] = preg_replace("#(?:.+\/{1})*([^\.]+)\.(.+)#i", '$1', $file); } else { # PHP 4.2.x code $dir = php4_scandir($dir); // See code snippet above if(!$ext) $ext = '\.[a-z]+'; $pattern = "#([^\.|\.\.$]+)$ext#i"; foreach ($dir as $file) if (preg_match($pattern, $file, $filename)) $arr[] = $filename[1]; } return (empty($arr) ? false : $arr); } ?> ---- Server IP: 213.92.11.19 Probable Submitter: 151.46.231.222 ---- X-Spam-Status: No, hits=3.1 required=5.0 tests=DATE_MISSING,FROM_NO_LOWER autolearn=no version=2.64 ---- Manual Page -- http://www.php.net/manual/en/function.scandir.php Edit -- http://master.php.net/note/edit/64114 Del: integrated -- http://master.php.net/note/delete/64114/integrated Del: useless -- http://master.php.net/note/delete/64114/useless Del: bad code -- http://master.php.net/note/delete/64114/bad+code Del: spam -- http://master.php.net/note/delete/64114/spam Del: non-english -- http://master.php.net/note/delete/64114/non-english Del: in docs -- http://master.php.net/note/delete/64114/in+docs Del: other reasons-- http://master.php.net/note/delete/64114 Reject -- http://master.php.net/note/reject/64114 Search -- http://master.php.net/manage/user-notes.php
