如何查找和删除上的重复项

[{"id":"1","name":"raj"},{"id":"2","name":"antony"},{"id":"1","name":"raj"}]

在这里，我如何替换重复条目，即，

{“id”：“1”，“name”：“raj”}

所以，我的输出应该是

[{"id":"1","name":"raj"},{"id":"2","name":"antony"}]

[{"id":"1","name":"raj"},{"id":"2","name":"antony"}]

这就是你能做到的

$j = '[{"id":"1","name":"raj"},{"id":"2","name":"antony"},{"id":"1","name":"raj"}]';
$ar = json_decode($j,true);
$unique = array_map("unserialize", array_unique(array_map("serialize", $ar)));
echo json_encode($unique);

结果你会得到
