How to sort an array of arrays in php?
Solution 1:
You can use usort function. Since PHP 5.4 you can use closure function:
usort($mainArray, function ($a, $b) {
$a_val = (int) $a['order'];
$b_val = (int) $b['order'];
if($a_val > $b_val) return 1;
if($a_val < $b_val) return -1;
return 0;
});
Or version for PHP < 5.4:
usort($mainArray, 'myCompare');
function myCompare($a, $b) {
$a_val = (int) $a['order'];
$b_val = (int) $b['order'];
if($a_val > $b_val) return 1;
if($a_val < $b_val) return -1;
return 0;
}
