To answer the original question, what do you mean by length? That's a bit
ambiguous. So, I'll take a guess.
If you mean the length of each element of the array, and it's a
one-dimensional array, you can use a combination of implode() and
strlen():
<?
$foo[] = '1';
$foo[] = '22';
$foo[] = '333';
echo strlen(implode($foo));
?>
This outputs 6, the length of 122333.
Hope that helps.
Chris
