How to sort an array on a certain variable in php? -


i have piece of var_dump of 1 of array items displayed here:

protected 'created_at' =>  object(carbon\carbon)[178] public 'date' => string '2014-01-23 00:00:00' (length=19) public 'timezone_type' => int 3 public 'timezone' => string 'europe/amsterdam' (length=16)

my question how can sort array on created_at variable? should descending.

thanks effort!

uasort() should trick!

see working example here.

uasort($data, function($a, $b) {   $first = $a['created_at']->format('u');   $second= $b['created_at']->format('u');    if ($first == $second) {     return 0;   }    return ($first < $second) ? -1 : 1; });

the callback using date's timestamp (->format('u');) compare 2 dates. please note, uasort() maintains key-value association while usort() not.
