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

mb_eregi — Regular expression match ignoring case with multibyte support
Executes the case insensitive regular expression match with multibyte support.
pattern
The regular expression pattern.
string
The string being searched.
matches
If matches are found for parenthesized substrings of
pattern
and the function is called with the
third argument matches
, the matches will be stored
in the elements of the array matches
.
If no matches are found, matches
is set to an empty
array.
$matches[1] will contain the substring which starts at the first left parenthesis; $matches[2] will contain the substring starting at the second, and so on. $matches[0] will contain a copy of the complete string matched.
Returns whether pattern
matches string
.

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.

Hinweis:
Die interne Kodierung oder die mit mb_regex_encoding() festgelegte Zeichenkodierung wird als Zeichenkodierung für diese Funktion genutzt.
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.
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
?>
