PHP实现的多维数组去重操作示例

两组多维数组测试数据：

$arr1 = Array (
    Array ( 'hostName' => '侯' ,'pcode2' => 111 ,'email' => '[email protected]', 'selfName' => 'h' ),
    Array ( 'hostName' => '体' ,'pcode2' => 222 ,'email' => '[email protected]', 'selfName' => 't' ),
    Array ( 'hostName' => '宗' ,'pcode2' => 333 ,'email' => '[email protected]', 'selfName' => 'z' ),
    Array ( 'hostName' => '侯' ,'pcode2' => 111 ,'email' => '[email protected]', 'selfName' => 'h' ),
    Array ( 'hostName' => '体' ,'pcode2' => 222 ,'email' => '[email protected]', 'selfName' => 't' ),
    Array ( 'hostName' => '宗' ,'pcode2' => 333 ,'email' => '[email protected]', 'selfName' => 'z' ),
);

$arr2 = Array (
    Array ( 'hostName' => '侯' ,'pcode2' => 111 ,'email' => '[email protected]', 'selfName' => 'h' ),
    Array ( 'hostName' => '体' ,'pcode2' => 222 ,'email' => '[email protected]', 'selfName' => 't' ),
    Array ( 'hostName' => '宗' ,'pcode2' => 333 ,'email' => '[email protected]', 'selfName' => 'z' ),
);

去重代码：

$arr = array_merge($arr1,$arr2);//合并数组
$arr = array_unique($arr, SORT_REGULAR);
var_dump($arr);

实现的效果

array(3) {
  [0]=>
  array(4) {
    ["hostName"]=>
    string(3) "侯"
    ["pcode2"]=>
    int(111)
    ["email"]=>
    string(10) "[email protected]"
    ["selfName"]=>
    string(1) "h"
  }
  [1]=>
  array(4) {
    ["hostName"]=>
    string(3) "体"
    ["pcode2"]=>
    int(222)
    ["email"]=>
    string(9) "[email protected]"
    ["selfName"]=>
    string(1) "t"
  }
  [2]=>
  array(4) {
    ["hostName"]=>
    string(3) "宗"
    ["pcode2"]=>
    int(333)
    ["email"]=>
    string(11) "[email protected]"
    ["selfName"]=>
    string(1) "z"
  }
}
