把第二个数据往第一个数组里一条一条追加，判断重复！

梅子雨

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

bs

$new_array=Array1+Array2;

估计未能满足LZ需求

数组能加吗？

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
)
