Code help

HI,

I need some help with code for finding the highest value of an array of variables.

Forexample the variables are $this->test[1] $this->test[2] and $this->test[3]

$this->test[1] = 2

$this->test[2] = 5

$this->test[3] = 1

How can I find the variable that has the highest value?. its obvious that $this->test[2] is the highest but how can we find this out using code?

Many thanks

 

This explains it better than I ever could:

http://php.net/manual/en/function.max.php

 

PHP:

$intArray = [1, 2, 3, 4, 5];
$highest = 0;
foreach($intArray as $key => $value) {
    if($value > $highest) {
        $highest = $value;
    }
}
echo $highest; // 5


That's a basic check with a loop, I'm sure there's other ways that I can't recall off the top of my head.

 

PHP:

$nums = [1, 2, 3, 4, 5];
$biggest = max($nums);

 

you should use this:

PHP:

$this->test = [2,5,1];
$max = max($this->test); //will return 5 because its the highest int in your array :)
