Do something with highest variable from an array of variables

[peterhuynh]

I have a set of variables with randomly assigned integers. 

$a = 1;
$b = 3;
$c = -1;

I put them in an array and sort them from highest to lowest.

$all = array( 
 'a' => $a,
 'b' => $b,
 'c' => $c
);
arsort($all);

I want to do something with the highest variable only if it is greater than 0.

How can I accomplish that?

 

Thank you.

You could use current() or array_shift to get the first element. Then run a simple if test.

Instead of the sort you could find the highest value with max($all)

OP here: I could be more specific.

 

The variables $a, $b, $c corresonding to three separate scripts: a.php, b.php, c.php.

 

If, among the three variables, $a ends up having the greatest value, then I want to execture a.php. And if $b ends up having the greatest value, then I want to execute b.php.

 

How can I do this?

 

Thanks.

@peterhuynh - It depends on your setup. You could look into using a header() redirect. Or maybe you could import the script to execute with something like require().
