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

You can lowercase your keys when assigning them to the array and also lowercase them when looking up the value.

Without modifying the array, but the whole data structure:

A really cumbersome way involves creating magic getter/setter methods, but would it really be worth the effort (note that the other methods have to be implemented too)?

m_values = array();
  } 

  public function __get($key)
  { 
    return array_key_exists($key, $this->m_values) ? $this->m_values[$key] : null;
  } 

  public function __set($key, $value)
  { 
    $this->m_attributes[$key] = $value;
  } 
}
