Question

我有两个多维数组我想只拿那些数组键值与第一个数组不同

这是我的两个数组：

$array1 =  Array
(
  [0] => Array
    (
        [id] => 1
        [serial] => k-0001
        [u_rec_id] => 1
        [employer_office] => uouuououou
        [job_type] => ouuou
        [job_title] => u
        [job_appointment_date] => 2013-07-15
        [job_duration] => ouu

    )

  [1] => Array
    (
        [id] => 2
        [serial] => k-0001
        [u_rec_id] => 1
        [employer_office] => DDC
        [job_type] => Manger
        [job_title] => Manager
        [job_appointment_date] => 2013-07-17
        [job_duration] => one year
          )


 )

这是我的第二个数组

$array2 =  Array
(
  [0] => Array
    (
        [id] => 1
        [serial] => k-0001
        [u_rec_id] => 1
        [employer_office] => uouuououou
        [job_type] => ouuou
        [job_title] => u
        [job_appointment_date] => 2013-07-15
        [job_duration] => ouu

    )

  [1] => Array
    (
        [id] => 2
        [serial] => k-0001
        [u_rec_id] => 1
        [employer_office] => ouo
        [job_type] => uououo
        [job_title] => udds
        [job_appointment_date] => 2013-07-17
        [job_duration] => uo
          )


 );

我尝试过array_diff和array_diff_assoc它也不适用于我我收到此错误

遇到PHP错误

严重性：注意

消息：数组到字符串转换

文件名：history / home.php

行号：729

Answer 1

这样的事情可以让你在那里，取决于你想要什么：

$diff = array_udiff($array1, $array2, function (array $a, array $b) {
    return (int)array_diff($a, $b);
});

调整比较功能以比较您想要比较的确切内容 http://php.net/array_udiff

Answer 2

foreach，array_unique以及array_udiff可能会对您有所帮助。

PHP手册：

对于一个简单的数组：

$result = array_unique($array);

在您的情况下，PHP手册中有一个功能：

<?php 
function specified_array_unique($array, $value) 
{ 
    $count = 0; 

    foreach($array as $array_key => $array_value) 
    { 
        if ( ($count > 0) && ($array_value == $value) ) 
        { 
            unset($array[$array_key]); 
        } 

        if ($array_value == $value) $count++; 
    } 

    return array_filter($array); 
} 
?>

有一篇文章与你所提出的相似; Stack Overflow - array_udiff

比较多维数组并返回它们在php中的值与第一个数组不同的键
