note 47066 added to function.preg-replace

If you want to avoid filename conflicts, for example when handling uploaded files, this regex will append a digit before the extension or increment an existing one. e.g. my_file.ext >> my_file_1.ext my_file1.ext >> my_file_2.ext <?php while ( file_exists ( "$uploaddir/$file_name" )) { $file_name = preg_replace ( "/^(.+?)(_?)(\d*)(\.[^.]+)?$/e", "'\$1_'.(\$3+1).'\$4'", $file_name ); } ?> ---- Manual Page -- http://www.php.net/manual/en/function.preg-replace.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+47066 Delete -- http://master.php.net/manage/user-notes.php?action=delete+47066&report=yes Reason: bad code -- http://master.php.net/manage/user-notes.php?action=delete+47066&report=yes&reason=bad+code Reason: spam -- http://master.php.net/manage/user-notes.php?action=delete+47066&report=yes&reason=spam Reason: useless example -- http://master.php.net/manage/user-notes.php?action=delete+47066&report=yes&reason=useless+example Reason: contains commercial links -- http://master.php.net/manage/user-notes.php?action=delete+47066&report=yes&reason=contains+commercial+links Reason: useless note -- http://master.php.net/manage/user-notes.php?action=delete+47066&report=yes&reason=useless+note Reject -- http://master.php.net/manage/user-notes.php?action=reject+47066&report=yes Search -- http://master.php.net/manage/user-notes.php
