php和xml有什么关系
PHP创建XML的方法示例基于DOMDocument类及SimpleXMLElement类本文实例讲述了PHP创建XML的方法。分享给大家供大家参考，具体如下：
使用DOMDocument类创建xml
config.php
|
|
<?php$doc = new DOMDocument('1.0','utf-8');$doc->formatOutput = true;//创建标签$mysql = $doc->createElement("mysql");$host = $doc->createElement("host");$username = $doc->createElement("username");$password = $doc->createElement("password");$database = $doc->createElement("database");//创建标签内容$hostval = $doc->createTextNode("127.0.0.1");$usernameval = $doc->createTextNode("root");$passwordval = $doc->createTextNode("1234");$databaseval = $doc->createTextNode("test");//绑定标签和内容$host->appendChild($hostval);$username->appendChild($usernameval);$password->appendChild($passwordval);$database->appendChild($databaseval);//关联标签之间的关系$doc->appendChild($mysql);$mysql->appendChild($host);$mysql->appendChild($username);$mysql->appendChild($password);$mysql->appendChild($database);$doc->save("config.xml"); |
config.xml
|
|
<?xml version="1.0" encoding="utf-8"?><mysql> <host>127.0.0.1</host> <username>root</username> <password>1234</password> <database>test</database></mysql> |
使用simplexml方法创建xml
config.php
|
|
<?php$mysql = new SimpleXMLElement('<?xml version="1.0" encoding="utf-8"?><mysql></mysql>');$host = $mysql->addchild("host","127.0.0.1");$host->addAttribute("note","localhost");$mysql->addchild("username","root");$mysql->addchild("password","1234");$mysql->addchild("database","test");header("Content-type:text/xml;charset=utf-8");echo $mysql->asXml();$mysql->asXml("config.xml"); |
config.xml
|
|
<mysql><host note="localhost">127.0.0.1</host><username>root</username><password>1234</password><database>test</database></mysql> |
希望本文所述对大家PHP程序设计有所帮助。
