This function returns true on success now. Previously, it returned the byte length
of the matched string if a match for pattern was found in
string and matches was passed.
If the optional parameter matches was not passed or
the length of the matched string was 0, this function returned 1.

| 7.1.0 |
mb_eregi() will now set matches to
an empty array, if nothing matched. Formerly,
matches was not modified in that case.

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.

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
?>
