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
)

First convert json string to array using json_decode and USE array_diff to find different value
Here's the code -
$arr1 = json_decode($jsonArray1);
$arr2 = json_decode($jsonArray2);
$newarr = array_diff($arr2, $arr1);
print_r($newarr); // php array format
json_encode($newarr); // json format

but your's Array ( [0] => 7.00 am To 8.00 am [1] => 1.00 pm To 2.00 pm [2] => 2.00 pm To 3.00 pm [6] => 10.00 am To 11.00 am ) like that

oh got it so you want to remove duplicate data too ..sorry mate ...i missed that
Try this:
//you have to decode arrays
$json1 = json_decode( $jsonArray1, true);
$json2 = json_decode( $jsonArray2, true);
//find duplicates
$find_duplicates = array_intersect($json1, $json2);
//remove duplicates from first array
$json1 = array_diff($json1, $find_duplicates);
///remove duplicates from second array
$json2 = array_diff($json2, $find_duplicates);

$out = array_values($json2); $arry_merge = (array_merge($json1,$json2)); echo json_encode($arry_merge).'--op';
