# [Plugin: WordPress Wiki] Call to undefined function array_fill_keys()

 * After updating to version 0.6, I get this error (showing up in the apache error
   logs) when I try to edit a wiki page:
 * `PHP Fatal error: Call to undefined function array_fill_keys() in /path/to/wordpress/
   wp-content/plugins/wordpress-wiki/wordpress-wiki.php on line 701`
 * I’ve commented out that line for now, but am worried that will bork ownership
   of edits.
 * Looks like array_fill_keys() requires PHP 5.2 or greater – any chance of a back
   port for those still having to run lesser versions of PHP? The server I use is
   still running PHP Version 5.1.6

 * Maybe it’s late but…
 * You could add this function on the top of wordpress-wiki.php:
 *     ```
       function array_fill_keys($target, $value = '') {
           if(is_array($target)) {
               foreach($target as $key => $val) {
                   $filledArray[$val] = is_array($value) ? $value[$key] : $value;
               }
           }
           return $filledArray;
       }
       ```
   
 * Copied from [php manual](http://php.net/manual/en/function.array-fill-keys.php)
   and works fine for me.
