比较两个json数组并删除PHP中的重复项

$json1 = '[{"id": 1, "name": "John"}, {"id": 2, "name": "Jane"}]';
$json2 = '[{"id": 2, "name": "Jane"}, {"id": 3, "name": "Bob"}]';

$array1 = json_decode($json1, true);
$array2 = json_decode($json2, true);

$mergedArray = array_merge($array1, $array2);

$uniqueArray = array_unique($mergedArray, SORT_REGULAR);

$jsonResult = json_encode($uniqueArray);

$json1 = '[{"id": 1, "name": "John"}, {"id": 2, "name": "Jane"}]';
$json2 = '[{"id": 2, "name": "Jane"}, {"id": 3, "name": "Bob"}]';

$array1 = json_decode($json1, true);
$array2 = json_decode($json2, true);

$mergedArray = array_merge($array1, $array2);
$uniqueArray = array_unique($mergedArray, SORT_REGULAR);
$jsonResult = json_encode($uniqueArray);

echo $jsonResult;

[{"id":1,"name":"John"},{"id":2,"name":"Jane"},{"id":3,"name":"Bob"}]
