Question

here i want compare two json array and remove duplicates.

 $jsonArray1 = '["7.00 am To 8.00 am","1.00 pm To 2.00 pm","2.00 pm To 3.00 pm"]';
    $jsonArray2 = '["7.00 am To 8.00 am","1.00 pm To 2.00 pm","2.00 pm To 3.00 pm","10.00 am To 11.00 am"]';

Answer 1

The solution using array_intersect and array_filter functions:

$json_str1 = '["7.00 am To 8.00 am","1.00 pm To 2.00 pm","2.00 pm To 3.00 pm"]';
$json_str2 = '["7.00 am To 8.00 am","1.00 pm To 2.00 pm","2.00 pm To 3.00 pm","10.00 am To 11.00 am"]';

list($arr1, $arr2) = [json_decode($json_str1), json_decode($json_str2)];
$common_items = array_intersect($arr2, $arr1);
$result = array_filter(array_merge($arr1, $arr2), function($v) use($common_items){
    return !in_array($v, $common_items);
});

print_r($result);

The output:

Array
(
    [6] => 10.00 am To 11.00 am
)
