Sorting of array in laravel

Question

I have a two array like this.

 $array5 = json_decode('[{"time":"12:08 PM","md5":1201},{"time":"01:00 PM","md5":1121},{"day":"03:03 PM","md5":1401},{"time":"03:36 PM","md5":1334}] 
',true);
 $array6 = json_decode('[{"time":"12:08 PM","ips":20},{"time":"01:00 PM","ips":10},{"time":"03:02 PM","ips":12},{"time":"03:36 PM","ips":11}]', true);

combined array using array_merge_recursive is:

[{"time":"12:08 PM","url":1201,"ips":20},{"time":"01:00 PM","url":1121,"ips":10},{"time":"03:03 PM","url":1401},{"time":"03:36 PM","url":1334,"ips":11},{"time":"03:02 PM","ips":12}]

Now i want to sort this array according to time.Is there any possible to way to sort this array according to time?

The posted text is JSON, not PHP code. Consequently, you don't have an array. Use json_decode() to create an array from it then use usort() to sort it as you please. — axiac

You may use Laravel array_sort helper method https://laravel.com/docs/5.4/helpers#method-array-sort

To avoid errors during comparison, use dates as Carbon opjects http://carbon.nesbot.com/docs/

$array = array_values(array_sort($array, function ($value) {
    return new Carbon($value['time']);
}));

To manage order we may use - $value["time"] Also, it's possible to convert time to Carbon instance to avoid errors during comparisons

You can use usort function of PHP

<?php
$arr_json = '[{"time":"12:08 PM","url":1201,"ips":20},{"time":"01:00 PM","url":1121,"ips":10},{"time":"03:03 PM","url":1401},{"time":"03:36 PM","url":1334,"ips":11},{"time":"03:02 PM","ips":12}]';
$arr = json_decode($arr_json,true);

function sort_by_time($a,$b)
{
  $a_time = strtotime($a['time']);
  $b_time = strtotime($b['time']);
  return $a_time > $b_time;
}
usort($arr, "sort_by_time");
print_r($arr);
