比较了 <parameter>array</parameter> 和 <parameter>arrays</parameter> 并返回不同之处。

注意和

<function>array_diff</function> 不同的是键名也用于比较。

<para>

不同的是使用了用户自定义的回调函数,而不是内置的函数。

在此示例中,键值对 <literal>"a" => "green"</literal> 在两个数组中都有,因此不在本函数的输出中。不同的是,键值对
|
||
<literal>0 => "red"</literal> 出现在输出中,这是因为第一个数组的 <literal>"red"</literal> 的 key 自动分配为
|
||
<literal>0</literal>,而在第二个数组中,由于键名 <literal>0</literal> 已经被 <literal>yellow</literal>
|
||
占用,key 分配为 <literal>1</literal>。

检查更深的维度。
