如何比较两个数组的值?

I have 2 arrays one retrieved from a database (saved results) and the other from an xml (new results)

我有两个数组，一个是从数据库中检索出来的(保存的结果)，另一个是来自xml(新结果)

$fromDB = array('123','124','524','15','616');
$fromXML = array('123','124','524','15','818');

I want to compare those two and see which values are old (fromDB) and which are new (fromXML) so to insert the old value in a different table.

我想比较这两个值，看看哪个值是旧的(fromDB)，哪个值是新的(fromXML)，以便将旧值插入到另一个表中。

How can i achieve this?
