Give this a shot:

PHP Code:

function highlight( $c, $q )
{
    $q = explode( '|', $q );
    for ( $i = 0, $len = count( $q ); $i < $len; $i++ )
    {
        $c = preg_replace
        (
            '/(' . preg_quote( $q[$i], '/' ) . ')/Ui',
            '<span class="z">\1</span>',
            $c
        );
    }
    return $c;
}
