Sort array by numeric keys
arrays, ksort, php, sorting
Solution
If you just want to reverse the order, use `array_reverse`:
$reverse = array_reverse($array, true);
The second parameter is for preserving the keys.
Problem
How can I sort this array by array keys? ``` array( 4 => 'four', 3 => 'three', 2 => 'two', 1 => 'one', ) ``` Desired result: ``` array( 1 => 'one', 2 => 'two', 3 => 'three', 4 => 'four', ) ```
