PHP taking an array of objects, get rid of the duplicates one

本文关键字：一个对象数组 PHP | 更新日期: 2023-09-27

我有这样一个数组:-

$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

可以看到，数组中的前两个对象是重复的，怎么能得到没有重复对象的相同数组，意思是:

$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。数组中的项数可以大于3个，其中重复的对象数可以大于2个。

Thanks to lot

使用用于删除重复的数组唯一函数

 $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);
