For loop question

jc94062

I'd like to test a number of values between 01 and 16, now I know I can test 1-16 easily with a for loop, but 01-16 needs an addition.

I can obviously do it like below...

for ($i=1; $i<=16; $i++) {
if ($i<=9) {$i = "0".$i;}
//code
}

I was just wondering if PHP already had a function/way of doing this?

for ($i=01 ... doesn't work, it just returns 1, 2, 3...

Thanks!

$some_array = array ("01","02","03" etc)
foreach ($some_array as $i) {
//code do something with $i
}
seems like a decent way to me

If I want to read use 17 instead of 16, or use $num_results though its a lot harder to alter an array...

Plus foreach isn't PHP3 compatable, my current site is, but I prefer to keep things compatable for v3 and 4.

$i=array("01","02","03","04","05","06","07","08","09","10","11","12","13","14","15","16");
for($j=0; $j<16; $j++){
Print $i[$j]."<br>";;
}

Yes, Daniel said the same, but as I said its a lot harder to expand it like that...

Plus its the same amount of code :-(

You could always use the push_array type stuff to expand it.. I am not really familiar with these functions in PHP but I know they exist.. You may want to check them out..
