PHP采取一系列对象，摆脱重复的对象

Question

我有这个数组：

$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

如您所见，数组中的两个第一个对象是重复的，没有重复的对象如何获得相同的数组，这意味着：

$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 

请注意，这是一个示例数组。 数组中的项目数可以大于三个，并且其中的重复对象数可以大于两个。

非常感谢

使用用于删除重复项的数组唯一功能

 $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);
