内置函数用不了，为什么？

Deprecated: mysql_connect(): The mysql extension is deprecated and will be removed in the future: use mysqli or PDO instead in F:\PHPweb\Web.php on line 3

php 5.5 以上mysqlｉ已经不推荐使用得，得用pdo 或是 mysqli

mysqli 为例，你得改成这样

header('Content-type:text/html;charset=utf-8');

$conn = new mysqli('localhost','root','','Info');
$conn->set_charset('utf8');
$sql = 'select * from stu limit 1';
$query = $conn->query($sql);

while($row = $query->fetch_array(MYSQLI_ASSOC))
var_dump($row);

<?php
header('Content-type:text/html;charset=utf-8');
mysql_connect('localhost','root','');
mysql_select_db('Info');
mysql_query("set names 'utf8'");
$result=mysql_query('select * from stu limit 1');
$row=mysql_fetch_assoc($result);
echo $row;
?>
