PHP简单读取xml文件的方法示例

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

$doc = new DOMDocument();
$filepath=$_SERVER['DOCUMENT_ROOT']."/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
);
}
}
