Example of a simple method for PHP to read xml files, and an example for php to read xml files

This example describes how PHP simply reads xml files. We will share this with you for your reference. The details are as follows:

I store the version number and other data information in the software version update in the xml file, and read the version information during use.

The content of the xml file is as follows:

<xml version="v1.01" encoding="utf-8"> <updataMessages><version>v1.8.7</version> </updataMessages></xml>

The following describes how PHP reads xml files.

$ Doc = new DOMDocument (); $ filepath = $ _ SERVER ['document _ root']. "/upload/versionpc/ios. xml "; // xml file path $ doc-> load ($ filepath); $ books = $ doc-> getElementsByTagName (" updataMessages "); foreach ($ books as $ book) {$ versions = $ book-> getElementsByTagName ("version"); $ version = $ versions-> item (0)-> nodeValue; $ newmsgs = $ book-> getElementsByTagName ("newmsg"); $ newmsg = $ newmsgs-> item (0)-> nodeValue; if ($ version2 = $ version) {$ return = array ("status" => 0, "msg" => "success");} else {$ return = array ("status" => 2, "msg" => "have new version", "data" => $ newmsg );}}
