Comparing

[Guest]

I have a whole bunch of variables in an array about 30 and I need to find the lowest one but know which one it is not just the value so i can change it what would be the best way of doing this without a whole mess of if statments? I do not want to sort because then they wont be where I would need them.

can you rephrase that just a bit

I almost understand it but not quite

I have an array example
array[0] = "100"
array[1] = "300"
array[2] = "24"
array[3] = "40"

I want to pick array[2] because it would be the lowest
how can i achieve this

Well, if you don't [b]have[/b] to keep the array in the same order, just run a sort() on it and echo the first value:
[code]
<?php
$nums = array(100, 300, 24, 40);
sort($nums);
echo $nums[0];
?>
[/code]

Otherwise, you'd need to do some sort of looping comparison like this:
[code]
$nums = array(100, 300, 24, 40);
$small = $nums[0]; // default to the first value
foreach ($nums as $num) {
  $small = $num < $small ? $num : $small;
}

echo $small; // holds the smallest value in the array
[/code]

Hope that helps!
