本文为大家讲解的是PHP中通过加号(+)合并数组的一个简单方法分享，感兴趣的同学参考下。通常，我们合并多个数组用的是array_merge()函数，其实，PHP手册中关于数组操作符的介绍给了我们更简单的方法，那就是"+"号，看看下面的例子就明白了（详细了解）代码： <?php $a = array('a' => 'a', 'b' => 'b'); $b = array('c' => 'c', 'd' => 'd'); $c = $a + $b; print('<pre>'); print_r($c); print('</pre>'); ?> 结果： Array ( [a] => a [b] => b [c] => c [d] => d ) 注意：加号

本文为大家讲解的是PHP中通过加号(+)合并数组的一个简单方法分享，感兴趣的同学参考下。

通常，我们合并多个数组用的是array_merge()函数，其实，PHP手册中关于数组操作符的介绍给了我们更简单的方法，那就是"+"号，看看下面的例子就明白了（详细了解）
代码：

<?php

$a = array('a' => 'a', 'b' => 'b');

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

$c = $a + $b;

print('<pre>');

print_r($c);

print('</pre>');

?>

结果：

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。
