PHP连接MYSQL数据库出错的时候出错处理

RT：Warning: mysql_connect() [function.mysql-connect]: Access denied for user 'root'@'localhost' (using password: YES) in E:\myweb\test\php\consql.php on line 11
链接错误Access denied for user 'root'@'localhost' (using password: YES)出现上面那句话，从“连接错误”开始是自己定义的or die("".mysql_error()); 提示错误语句，不过我不想出现上面的Waring 怎么去掉他，代码如何请大虾详细点！~~

Answer 1

<?php
# FileName="Connection_php_mysql.htm"
# Type="MYSQL"
# HTTP="true"
$hostname_conn = "127.0.0.1";
$database_conn = "test";
$username_conn = "root";
$password_conn = "root";
$conn = mysql_pconnect($hostname_conn, $username_conn, $password_conn) or trigger_error(mysql_error(),E_USER_ERROR);
?>

Answer 2

E:\myweb\test\php\consql.php on line 11 11行的代码是什么

Answer 3

代码没错，只是没有加载php_mysql.dll这个extension
修改php.ini后要重启apache才行，不然你修改的效果不会显示出来的
