In this array, there is a field status, and I need to keep only one entry with the same status which means I need picked_up status only once. And I am expecting the last entry with the specified status in the result array. I need to apply the same logic to all statuses, eg. on_his_way, accepted etc.
CodePudding user response：
If you need only latest entry for each unique status, you can simply use status's value as a key in another associative array and keep overriding it at every iteration in the loop. In the end, you will only be left with unique results with latest entries.
Say, you have this array in a variable called $data, then you could loop like below:
<?php
$set = [];
foreach($data as $o){
$set[ $o->status ] = $o;
}
$set = array_values($set);// if you don't like status keys
print_r($set);
CodePudding user response：
$input = array_map("unserialize" , array_unique(array_map("serialize", $input)));
array_map - Applies the callback to the elements of the given array
serialized - Generates a storable representation of a value
unserialize - Creates a PHP value from stored representation
