question about using the min function

rakennedy75

Ok, I am using the min tag to decide which value is lowest. Works fine of course but I need to do something a little extra. I have two corresponding arrays.. for example:

$vars = Array("item1", "item2", "item3");
$vals = Array("400", "200", "600");
$low = min($vals);
echo $low;

This works, it prints out the lowest value fine. What if I want to pull the corresponding variable in the vars array.

So if it prints out the value form $vals of 200 how would vars know which item to pull. I guess essentially what i am asking, is if there is a way to reference the index value and so I can refer that to the vars array. In the end I want to be able to print out something like this...

item2: 200

hope this makes sense, thanks for your time and help.

Look at [man]array_filter[/man].

$vars = array('item1', 'item2', 'item3');
$vals = array('400', '200', '600');

foreach ($vals as $key => $value)
{
	if ($value == min($vals))
	{
		echo 'the min index in $vals is <b>' . $value . '</b><br>
		the corresponding index in $vars is <b>' . $vars[$key] . '</b>';
		break;
	}
}

excellent, thanks for the help, just what I was looking for

Or skip the loop and use [man]array_search[/man]

good call, much better than my loop.
