PHP中如何连接Mysql以及读取数据

// open the connection

$conn = mysql_connect(host名, 用户名, 密码);

// pick the database to use

mysql_query("SET NAMES UTF8");

mysql_select_db(数据库名,$conn);

// create the SQL statement

$sql = "SELECT * FROM 表名";

// execute the SQL statement

$result = mysql_query($sql, $conn) or die(mysql_error());

//go through each row in the result set and display data

while ($newArray = mysql_fetch_array($result)) {

// give a name to the fields，这个只是例子

$tid = $newArray['tid'];

//以下就是各自的应用编程

}
