如何使用PHP解压xml文件

我的

PHP

系统上有一个压缩的

XML

文件

如何将其解压缩以加载到

XMLDOM

我每个

zip

存档只有一个

XML

文件

---

提前感谢。

您可以使用php类，即：

open（$zipFile））
{
//获取zip文件中的xml文件名
$xmlFile=$zip->getNameIndex（0）；//您只有一个xml文件在zip的IDE中
$zip->close（）；
//读取zip中的xml文件，而不将其解压缩到磁盘（内存）
$xml=file_get_contents（“zip://$zipFile#$xmlFile”）；
//创建新文档
$dom=新的DOMDocument（'1.0'，'UTF-8'）；
//加载xml文件
$dom->loadXML（$xml）；
//在这里，您可以操作XMLDOM、添加、删除节点等。
//保存并回显XML
echo$dom->saveXML（）；
}否则{
echo“zip打开失败”；
}

注:

我已经用测试了代码，并且它按照预期工作
