note 38531 added to function.glob

Just a small modification of Jirka's glob function; I was running into problems with foreach. E.g. foreach( glob( "/path/*.doc" ) as $entry ) { [something] } Assuming the folder contained no files with a .doc extension glob appears to return a null value (?) and I would get an error message stating that an invalid argument was passed to the foreach loop. The following modification appears to work pretty good with PHP 4.2.2 function glob ($pattern) { $path_parts = pathinfo ($pattern); $pattern = '^' . str_replace (array ('*', '?'), array ('(.+)', '(.)'), $path_parts['basename'] . '$'); $dir = opendir ($path_parts['dirname']); while ($file = readdir ($dir)) { if (ereg ($pattern, $file)) $result[] = "{$path_parts['dirname']}/$file"; } closedir ($dir); // my changes here if ( isset($result) ) return $result; return (array) null; } I hope this might help someone and any suggections are welcome. ~CL ---- Manual Page -- http://www.php.net/manual/en/function.glob.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+38531 Delete -- http://master.php.net/manage/user-notes.php?action=delete+38531&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+38531&report=yes Search -- http://master.php.net/manage/user-notes.php
