我的网站需要很长时间才能加载并出现以下错误：
Warning: mysql_connect(): MySQL server has gone away in C:\xampp\htdocs\test\inc\scripts\mysql_connect.inc.php on line 9
Warning: mysql_connect(): Error while reading greeting packet. PID=2256 in C:\xampp\htdocs\test\inc\scripts\mysql_connect.inc.php on line 9
Warning: mysql_connect(): MySQL server has gone away in C:\xampp\htdocs\test\inc\scripts\mysql_connect.inc.php on line 9
Fatal error: Maximum execution time of 30 seconds exceeded in C:\xampp\htdocs\test\inc\scripts\mysql_connect.inc.php on line 9
我正在使用的代码：
<?php
$conn_error = 'Colud not connect.';
$mysql_host = "localhost:8080";
$mysql_user = "Harry";
$mysql_pass = "";
$mysql_db = 'testsite' ;
mysql_connect($mysql_host, $mysql_user, $mysql_pass) or die("Couldn't Connect") ;
mysql_select_db($mysql_db) or die($conn_error);
echo 'Connected!' ;
?>
知道为什么会这样吗？
