This article mainly introduces the method of PHP to simply read xml files, involving PHP implementation techniques for xml file node operations. Friends in need can refer to the version number in

I will update the software version. The data information is stored in the xml file, and the version information is read out when used.

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 is how PHP reads the xml file

$doc = new DOMDocument();
$filepath=$_SERVER[&#39;DOCUMENT_ROOT&#39;]."/upload/versionpc/ios.xml"; //xml文件路径
$doc->load($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
);
}
}
Copy after login
