代码：

复制代码 代码如下:


$a = array('a' => 'a', 'b' => 'b');
$b = array('c' => 'c', 'd' => 'd');
$c = $a + $b;
print('

'); <br>print_r($c); <br>print('
Copy after login
');
?>

结果：

复制代码 代码如下:


Array
(
[a] => a
[b] => b
[c] => c
[d] => d
)


注意：加号和array_merge()函数还是有区别的，就是当用加号合并数组时，如果数组间存在同名的键，那么保留前面数组对应的键值，而array_merge()函数正好相反。
