This function does not work - it is not case insensitive for non latin characters.

I simulated it:

<?php

   $text = 'Äpfel';

   mb_internal_encoding( 'utf-8' );

   printf( "%d\n", mb_eregi( 'äpfel', $text ) ); // Output: 0

   printf( "%d\n", mb_ereg( 'äpfel', mb_strtolower( $text ) ) ); // Output: 1

   printf( "%d\n", mb_eregi( 'äpfel', mb_strtolower( $text ) ) ); // Output: 1

?>

When this function is perfected, and is not experimental, it may be very usefull in the searching and pinpointing of places inside large text files.
