Select high from array

[a1amattyj]

Hi,

 

How do i select the highest key from an array, e.g:

 

array(4) { ["Double-Glazing"]=> int(3) ["test"]=> int(1) ["test2"]=> int(1) ["test5"]=> int(7) }

 

How do i select the "test5" only as it has the highest int?

 

Thanks!

$arr = array('keya' => 11 , 'keyb' => 3, 'keyc' => 15, 'keyd' => 4);

foreach ($arr as $key=>$val)
{
  if($highest < $val)
  {
$highest = $val;
$highest_key = $key;
  }
}

echo $highest_key;

Not sure i fully understand what you are doing, but look at

<?php

$values = array("Double-Glazing" => 3, "test" => 1, "test2" => 1, "test5" => 7);

rsort($values);

echo $values[0]; // 7

?>
