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

?>

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

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.
