Array Manipulation

[joe2]

Hi,

Array ( [0] => 0 [1] => 10 [2] => 10 [3] => 10 ) Array ( [0] => 7 )

How can i take out the minimum value of each array index. In this case
Array ( [0] => 0
And
Array ( [0] => 7

i.e. 0,7

Thanks

hmm... are you trying to search for the smallest value or the element with the smallest index?

For the former, you can use [man]min/man
For the latter, you appear to be using a numerically indexed array so it should always be 0.

Thanks for the information.

Actually values will change at the run time for e.g for the first one there are 4 value and the second one there is only one value.

i have to find out the minimum value in the array.

i have to find out the minimum value in the array.

Well, if you insist you could use:

$count = count($array);
if ($count > 0) {
	$lowest = $array[0];
	for ($i = 1; $i < $count; $i++) {
		if ($array[$i] < $lowest) {
			$lowest = $array[$i];
		}
	}
} else {
	$lowest = NULL;
}

... or you could take my suggestion and use [man]min/man.

Definitly i will use min()

Thanks.
