setKeyAttribute(string $attribute, bool $remove = true)

Sets the attribute which value is to be used as key.

This is useful when you have an indexed array that should be an associative array. You can select an item from within the array to be the key of the particular item. For example, if "id" is the "key", then:

array(
    array('id' => 'my_name', 'foo' => 'bar'),
);

becomes

 array(
     'my_name' => array('foo' => 'bar'),
 );

If you'd like "'id' => 'my_name'" to still be present in the resulting array, then you can set the second argument of this method to false.

Parameters

string	$attribute	The name of the attribute which value is to be used as a key
bool	$remove	Whether or not to remove the key

string getKeyAttribute()

Retrieves the name of the attribute which value should be used as key.

Return Value
