   print_r($matches);
}

    [0] => �25.00
    [1] => �

Look at this discussion : preg_match and UTF-8 in PHP

Natively, preg_match() doesn't support Unicode string. You have to add the u modifier to your regular expression to tell the pcre engine to consider both the expression and the subject string as Unicode strings.

$input = '£25.00';
$matches = array();

if (preg_match('/([\$€£])/u', $input, $matches)) {
    print_r($matches); 
}

Prints : 

Array
(
    [0] => £
    [1] => £
)
