How do I sort an array by key?
The key to sorting by key, is to add a k before the sort to get the function ksort.
This takes the name of the array as the parameter, and works like this:
$myworld = array(”c”=>”best”,”a”=>”make”,”b”=>”men”);
print_r($myworld);
?>
his prints:
Array
(
[c] => best
[a] => make
[b] => men
We need to use ksort to get the right key order:
$myworld = array(”c”=>”best”,”a”=>”make”,”b”=>”men”);
ksort($myworld);
print_r($myworld);
?>
Array
(
[a] => make
[b] => men
[c] => best
)
