Note that this function matches a string from the beginning only (though not necessarily till the end):
<?php
$test = mb_ereg_match("a", "some apples"); // returns false
$test = mb_ereg_match("a", "a kiwi"); // returns true
?>
If you want to check for a match anywhere in the string, use the wild-card & repeat operators .*
<?php
$test = mb_ereg_match(".*a", "some apples"); // returns true
?>
The behaviour of mb_ereg_match to imply a ^ at the beginning of the pattern stands in stark contrast to the behaviour of mb_ereg where ^ is NOT implied.
Switching between those two routines (because the need to extract a subpattern changes) requires careful consideration when to compensate for this surprising inconsistence.
