Executes the case insensitive regular expression match with multibyte support.

Parameter-Liste

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.

Rückgabewerte

Returns whether pattern matches string.

Changelog

Version Beschreibung
8.0.0 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.

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
?>
