php: Array keys case *insensitive* lookup?

Question

$myArray = array (\'SOmeKeyNAme\' => 7);  

I want $myArray[\'somekeyname\'] to return 7.
Is there a way to do this

Answer 1

I just had same problem and I could not change original array. I use few array functions for it.

Parameters

$search = "AbCd";
$array = array("AbcD"=>"11","Bb"=>"22");

Solution

$lower_search = strtolower($search);
$array_of_keys = array_map("strtolower",array_keys($array));
$idx = array_search($lower_search,$array_of_keys);
if($idx !== FALSE)
    echo array_values($array)[$idx];

Make it shorter

if(($idx=array_search(strtolower($search),array_map("strtolower",array_keys($array))))!==FALSE)
    echo array_values($array)[$idx];
