[RESOLVED] array functions

[kterry]

Is there a way to tell if you are at last element in the array in a foreach loop?

Or is there an easier way to comma separate values in an array? Obviously the last element doesn't need a comma after it.

Maybe. For example, if you are iterating over a numerically indexed array, you just need to compare the key with the size of the array.

You could consider using [man]implode/man.

implode works perfectly.

<?php
$a = array('test', 'test2', 'test3');
$b = implode(', ', $a);
echo $b;
?>

Outputs: test, test2, test3
