<HTML>
<HEAD>
<TITLE>MySQL Databases</TITLE>
</HEAD>
<BODY>
Databases on localhost:
<? echo "$db_list"; ?>
</BODY>
</HTML>
3，列出数据库变量信息

<html>
<head>
<title>输出一些 mysql 数据库信息-www.jbxue.com</title>
</head>
<body>
<?php
$user = "root";
$pass = "123456";
$link = mysql_connect( "192.168.0.10", $user, $pass );
if ( ! $link )
die( "Couldn't connect to MySQL" );

$db_res = mysql_list_dbs( $link );
$num = mysql_num_rows( $db_res );

for( $x = 0; $x < $num; $x++ )
print mysql_tablename( $db_res, $x )." ";

mysql_close( $link );
?>
</body>
</html>
4，用变更储存 mysql 连接信息

<?php
//
$hostname="192.168.0.10";
$username="root";
$password="123456";
$dbname="test_news";
$usertable="Employee";
$yourfield = "FirstName";
