This article mainly introduces the PHP parsing xml format data tool class, involving PHP's related operation skills for adding, obtaining, and parsing xml format data nodes. Friends in need can refer to the following
The examples in this article are described PHP parsing xml format data tool class. Share it with everyone for your reference, the details are as follows:
