xml做mysql的配置文件及php对配置文件信息的读取 连接数据库

localhost

root

123

以上是xml类型的mysql配置文件

$doc=new DOMDocument('1.0','utf-8');

$doc->load("mysql_xml.xml");

$mysql=$doc->getElementsByTagName("mysql");

$mysql1=$mysql->item(0);

$servicer=$mysql1->getElementsByTagName("servicer")->item(0)->nodeValue;

//echo $servicer;

$root=$mysql1->getElementsByTagName("root")->item(0)->nodeValue;

//echo $root;

$pw=$mysql1->getElementsByTagName("pw")->item(0)->nodeValue;

//echo $pw;

$link=mysql_connect("$servicer","$root","$pw")or die('连接数据库失败');

mysql_select_db('user',$link) or die('失败');

$sql='select *from usertable;';

$res=mysql_query($sql);

while($rows=mysql_fetch_row($res)){

foreach($rows as $value)

{echo $value;}

}

对配置文件信息的获取，后进行应用，访客用时该数据库即可
