I have an array as follow in php. It contains of two array of std objects. How can I sort it based on report_date element? as you see report_date is unix time.
Array(
[current] => Array
(
[0] => stdClass Object
(
[city_fa_name] => مشهد ۳
[report_date] => 1440963000
[id] => 3
)
[1] => stdClass Object
(
[city_fa_name] => مشهد ۳
[report_date] => 1441049400
[id] => 2
)
)
[saved] => Array
(
[0] => stdClass Object
(
[city_fa_name] => مشهد ۳
[report_date] => 1441049400
[id] => 2
)
[1] => stdClass Object
(
[city_fa_name] => مشهد ۳
[report_date] => 1441135800
[id] => 1
)
))
