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

match with multibyte support, and returns 1 if matches are found.
If the optional regs parameter was specified, the function
returns the byte length of matched part, and the array
regs will contain the substring of matched
string. The function returns 1 if it matches with the empty
string. If no matches are found or an error happens, FALSE will be
returned.

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
?>
