I have a question of my own! I found out yesterday that you can add so-called variables in your regular expressions, although technically they're more like naming schemes for your array indexes. They can be done like so:

php Code:

$szText = 123;
preg_match('/(?P<first>\d{1})(?P<second>\d{1})(?P<third>\d{1})/', $szText, $aMatches);
print_r($aMatches);

Which would output:

Code:

Array
(
    [0] => 123
    [first] => 1
    [1] => 1
    [second] => 2
    [2] => 2
    [third] => 3
    [3] => 3
)

My question is, aside from what the correct term for them are, is this: is there any way to prevent the function from also adding the numeric indexes to the array and leave you with a pure associative array?
