PHP采取一系列對象，擺脫重復的對象

Question

我有這個數組：

$arr
: array = 
  0: object(myObject) = 
    id: string = 188
    CaseNo: string = 1
    strname: string = Apple
    strContact: string = Alice
  1: object(myObject) = 
    id: string = 188
    CaseNo: string = 1
    strname: string = Apple
    strContact: string = Alice
  2: object(myObject) = 
    id: string = 189
    CaseNo: string = 3
    strname: string = Amazon
    strContact: string = Jules

如您所見，數組中的兩個第一個對象是重復的，沒有重復的對象如何獲得相同的數組，這意味着：

$arr
: array = 
  0: object(myObject) = 
    id: string = 188
    CaseNo: string = 1
    strname: string = Apple
    strContact: string = Alice
  1: object(myObject) = 
    id: string = 189
    CaseNo: string = 3
    strname: string = Amazon
    strContact: string = Jules 

請注意，這是一個示例數組。 數組中的項目數可以大於三個，並且其中的重復對象數可以大於兩個。

非常感謝

使用用於刪除重復項的數組唯一功能

 $a = array(
        0 => array (
            "ID" => 188,
            "CaseNo" => 1,
            "strname" => 'Apple',
            "strContact" => 'Alies'

        ),
        1 => array (
             "ID" => 188,
            "CaseNo" => 1,
            "strname" => 'Apple',
            "strContact" => 'Alies'

        ),
        2 => array (
            "ID" => 189,
            "CaseNo" => 1,
            "strname" => 'Amazon',
            "strContact" => 'Jules'

        ),
);
echo "<pre>";
$ab = array_map("unserialize", array_unique(array_map("serialize", $a)));
print_r($ab);
