原生态 php连接mysql

<?php
$host = 'localhost';
$user = 'root';
$pass = '';
$dbname = 'test';
$con = mysql_connect($host,$user,$pass) or die('can not connect to database'.mysql_error());

mysql_query('set name utf8');
mysql_select_db($dbname);

$sql = 'select * from t_account';

$data = mysql_query($sql);

$allrows = mysql_num_rows($data);

while($row = mysql_fetch_assoc($data)){
$sdata[] = $row ;
}

echo '<meta http-equiv="Content-type" content="text/html:charset=utf-8">';
echo '<pre>';
var_dump($data); //resource(3) of type (mysql result) 连接mysql 返回结果是 资源类型
var_dump($allrows); //一共有多少条数据
var_dump($sdata); //

//associate 联合 mysql_fetch_assoc()每次取出一条, while循环, 如果有数据,就存到数组中
