PHP从数组中删除重复的对象

Question

我已经尝试了各种 PHP 逻辑和 PHP 的内置函数来删除重复值，但它不起作用没有出现任何错误，但是如果使用 array_unique() in_array() 我所有的 JQuery 和 CSS 都不起作用删除数组中的重复对象

这就是我如何创建我的 person_row_array在 while 循环中:

$person_row = Person::findByID($pi_claimant_row->person_id);
$person_row_array[] = $person_row;

对象 print_r 如下:

Array
(
[0] => stdClass Object
    (
        [id] => 12
        [flat_no] => 
        [house_no] => *
        [street] => 
        [town] => 
        [postcode] => *
        [county] => 
    )

[1] => stdClass Object
    (
        [id] => 14
        [flat_no] => 2
        [house_no] => 33
        [street] => Street
        [town] => Town
        [postcode] => BB
        [county] => County
    )

[2] => stdClass Object
    (
        [id] => 14
        [flat_no] => 2
        [house_no] => 33
        [street] => Street
        [town] => Town
        [postcode] => BB
        [county] => County
    )

[3] => stdClass Object
    (
        [id] => 14
        [flat_no] => 2
        [house_no] => 33
        [street] => Street
        [town] => Town
        [postcode] => BB
        [county] => County
    )

[4] => stdClass Object
    (
        [id] => 15
        [flat_no] => FN
        [house_no] => HN
        [street] => Street
        [town] => Nelson
        [postcode] => PC
        [county] => Manchester
    )

[5] => stdClass Object
    (
        [id] => 15
        [flat_no] => FN
        [house_no] => HN
        [street] => Street
        [town] => Nelson
        [postcode] => PC
        [county] => Manchester
    )

[6] => stdClass Object
    (
        [id] => 16
        [flat_no] => FN
        [house_no] => house
        [street] => Manchester Road
        [town] => Town
        [postcode] => M1 4MK
        [county] => County
    )

)

我想删除那些重复的，请帮忙，请不要建议我使用 array_unique() 我过去几个小时一直在尝试这个没有工作，但如果你能告诉我任何其他方式或添加对象，如果已经不退出。

请注意，这是假数据，我只想删除那些具有相似 ID 的数组。

此致

试试下面的代码

function my_array_unique($array, $keep_key_assoc = false){
    $duplicate_keys = array();
    $tmp = array();       

    foreach ($array as $key => $val){
        // convert objects to arrays, in_array() does not support objects
        if (is_object($val))
            $val = (array)$val;

        if (!in_array($val, $tmp))
            $tmp[] = $val;
        else
            $duplicate_keys[] = $key;
    }

    foreach ($duplicate_keys as $key)
        unset($array[$key]);

    return $keep_key_assoc ? $array : array_values($array);
}
