note 49952 added to function.substr

It is also good to use substr() to get a file extension when manipulating with files. For example: <?php $dir = "/full/path/to/folder"; if(is_dir($dir)) { if($dh = opendir($dir)) { while(($file = readdir($dh)) !== false) { if(substr($file,strlen($file)-4,4) == ".txt") { echo "Filename: $file<br/>\n"; } } closedir($dh); } else { echo "Cannot open directory"; } } else { echo "Cannot open directory"; } ?> Hopefully this helps ---- Manual Page -- http://www.php.net/manual/en/function.substr.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+49952 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+49952&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+49952&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+49952&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+49952&report=yes&reason=useless Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+49952&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+49952&report=yes Search -- http://master.php.net/manage/user-notes.php
