Simple example sharing of adding data to xml file in php

This article mainly introduces a simple example of adding data to an xml file in PHP. Interested friends can refer to it. I hope it will be helpful to everyone.

xml file: stu.xml:

    张三 80 90 70   李四 60 90 75   

The above file stu.xml provides partial *.

Now you need to add a zongfen attribute to each xuesheng node and its value is equal to the value of yuwen shuxue yingyu

As shown below:

    张三 80 90 70 240   李四 60 90 75 2225   

Use php to implement:

load( ‘stu.xml' ); $students = $doc->getElementsByTagName( “xuesheng” ); foreach($students as $stu){ $yuwen = $stu->getElementsByTagName( “yuwen” )->item(0)->nodeValue; $shuxue = $stu->getElementsByTagName( “shuxue” )->item(0)->nodeValue; $yingyu = $stu->getElementsByTagName( “yingyu” )->item(0)->nodeValue; $zongfen = $stu->getElementsByTagName( “zongfen” )->item(0)->nodeValue; if($zongfen){ echo “节点已经存在了，不再添加!”; continue; } $zongfen = $yuwen+$shuxue+$yingyu; $newNode = $doc->createElement(“zongfen”,$zongfen); $stu->appendChild($newNode); } $result = $doc->saveXML(‘stu.xml'); ?>
