        "street": "Sr",
        "contactnum": "1234"
    }]
}]

这是我来自 ajax 请求的结果我想从服务器端或 jquery 端的结果中删除重复项我已经尝试过最常见的删除重复数组的方法，例如

$input = array_map("unserialize", array_unique(array_map("serialize", $new_data)));
$new_data1 = array_values($input);
echo json_encode($new_data1, JSON_UNESCAPED_UNICODE);

$new_data 中的哪里是我的选择查询的结果。 print_r($new_data) 将导致

Array(
    [2015 - 07 - 018] => Array(
        [sys_id] => 2015 - 07 - 018[account_id] => 2015 - 07 - 018[Names] => Array(
            [0] => Array(
                [fname] => Jackie[mname] => Lee[lname] => Chan[suffix] => Jr[city] => Tokyo[town] => Shinagawa - ku[dstrct] => District 2[street] => Jr[contactnum] => 1234)[1] => Array(
                [fname] => Jackie[mname] => Lee[lname] => Chan[suffix] => Jr[city] => Tokyo[town] => Shinagawa - ku[dstrct] => District 2[street] => Jr[contactnum] => 1234)[2] => Array(
                [fname] => Jackie[mname] => Lee[lname] => Chan[suffix] => Jr[city] => Tokyo[town] => Shinagawa - ku[dstrct] => District 2[street] => Jr[contactnum] => 1234)[3] => Array(
                [fname] => Jackie[mname] => Lee[lname] => Chan[suffix] => Sr[city] => Tokyo[town] => Shinagawa - ku[dstrct] => District 2[street] => Sr[contactnum] => 1234)[4] => Array(
                [fname] => Jackie[mname] => Lee[lname] => Chan[suffix] => Sr[city] => Tokyo[town] => Shinagawa - ku[dstrct] => District 2[street] => Sr[contactnum] => 1234)[5] => Array(
                [fname] => Jackie[mname] => Lee[lname] => Chan[suffix] => Sr[city] => Tokyo[town] => Shinagawa - ku[dstrct] => District 2[street] => Sr[contactnum] => 1234))))

Update

我试过print_r($new_data1);的结果和print_r($new_data);的结果一模一样

寻找删除重复的方法我发现了这个

function super_unique($array) { $result = array_map("unserialize", array_unique(array_map("serialize", $array))); foreach($result as $key => $value) { if (is_array($value)) { $result[$key] = super_unique($value); } } return $result; }

我现在要做的任务是重新索引数组，因为输出是

Array ( [1] => Array ( [sis_id] => 2015-07-018 [account_id] => 2015-07-018 [Names] => Array ( [0] => Array ( [fname] => Jackie [mname] => Lee [lname] => Chan [suffix] => Jr [city] => Tokyo [town] => Shinagawa-ku [brgy] => District 2 [contactnum] => 1234 ) [3] => Array ( [fname] => Jackie [mname] => Lee [lname] => Chan [suffix] => Sr [city] => Tokyo [town] => Shinagawa-ku [brgy] => District 2 [contactnum] => 1234 ) ) ) ) 

我想要输出的旧格式

如果您将数组中的每个对象序列化为字符串（我认为 json 最简单），然后使用本机函数删除重复项，然后反序列化回对象，该怎么办？

Sudo 代码如下所示：

$serialized_array = [];
foreach($new_data as $data) {
    $serialized_array[] = json_encode($data);
}

$new_data = []; //reset new_data
$unique = array_unique($serialized_array);
foreach($serialized_array as $string) {
    $new_data[] = json_decode($string);
}
//new_data should now only contain unique data

你正在做的事情和这之间的主要区别是序列化和反序列化每个对象单独而不是整个数组。这是关键。
