Idiot Question

[lupus2k5]

OK, this sounds really stupid, but...

<?php
$var[1] = "value";
$var[2] = "value";
$var[3] = "value";
$var[4] = "value";
?>

Obviously there are 4 elements to this array, but how do I make my script count them?
E.g.

<?php
$var[1] = "value";
$var[2] = "value";
$var[3] = "value";
$var[4] = "value";
$numberOfElements = 4;
?>

This probably has something to do with for() or foreach(), but I never really understood those, so....

Thanks ahead of time.

$numberOfElements = count($var);

That's it? Wow.

Uh, thanks.

Yep, that's it. The [man]count/man function was made for this 😉

Don't forget to mark this thread resolved (if it is).
