find location of maximum value in array

[Bou]

Hello

I have an array of values, defined with a for next loop looking like this:

for($i=0;$i<sizeof($data);$i++)
 {$alt[]=..
  }

Now I want to know where the maximum value occurs in the array $alt. How do I do this?

The function max() only returns the maximum value.

All help is appreciated

you could use arsort() to sort the array in reverse order, then pick off the first element. arsort() will maintain key association so you can tell where in the original array the maximum value was. or, you could take that value you got from max() and use it with the array_search() function.
