# PHP Notice: Undefined Index for $ints array

 * In version 2.2.4 line 871 reads:
 *     ```
       if ($ints[strtolower($key)]) {
       ```
   
 * The `$ints` array only contains elements for “integer-type” columns, so this 
   test generates a PHP Notice message for every non-integer column. This fix seems
   to correct the problem:
 *     ```
       if ( isset( $ints[strtolower($key)] ) ) {
       ```
