标题: php合并两个二维数组,如果有两组相同值,只取一个,如何实现
循环出来的数组如下：我现在要合并这两个数组，相同的值我主要取第二个数组的值，请问该如何实现，谢谢！

把第二个数据往第一个数组里一条一条追加，判断重复！

作者: 梅子雨 时间: 2009-12-02 13:53
反转就去掉了重复的值了

合并更简单

3楼的很经典，我只会传统的做法。

3楼的的确很牛啊。

思维很开阔

$new_array=Array1+Array2;

估计未能满足LZ需求

数组能加吗？

作者: 24xinhui 时间: 2009-12-04 00:10
有现成的函数

array_merge -- 合并一个或多个数组

说明
array array_merge ( array array1 [, array array2 [, array ...]] )

array_merge() 将一个或多个数组的单元合并起来，一个数组中的值附加在前一个数组的后面。返回作为结果的数组。

如果输入的数组中有相同的字符串键名，则该键名后面的值将覆盖前一个值。然而，如果数组包含数字键名，后面的值将不会覆盖原来的值，而是附加到后面。

如果只给了一个数组并且该数组是数字索引的，则键名会以连续方式重新索引。

<?php
$array1 = array("color" => "red", 2, 4);
$array2 = array("a", "b", "color" => "green", "shape" => "trapezoid", 4);
$result = array_merge($array1, $array2);
print_r($result);
?>

array_merge
(PHP 4, PHP 5)

array_merge -- 合并一个或多个数组
说明
array array_merge ( array array1 [, array array2 [, array ...]] )

array_merge() 将一个或多个数组的单元合并起来，一个数组中的值附加在前一个数组的后面。返回作为结果的数组。

如果输入的数组中有相同的字符串键名，则该键名后面的值将覆盖前一个值。然而，如果数组包含数字键名，后面的值将不会覆盖原来的值，而是附加到后面。

如果只给了一个数组并且该数组是数字索引的，则键名会以连续方式重新索引。

例子 1. array_merge() 例子

<?php
$array1 = array("color" => "red", 2, 4);
$array2 = array("a", "b", "color" => "green", "shape" => "trapezoid", 4);
$result = array_merge($array1, $array2);
print_r($result);
?>

上例将输出：

Array
(
[color] => green
[0] => 2
[1] => 4
[2] => a
[3] => b
[shape] => trapezoid
[4] => 4
)
