Homephp教程php手册php配置mysql与怎么测试配置数据库成功

如果你是初次配置 php mysql apache的话,我们要怎么测试php连接数据库成功了,只要创建一个test.php文件,然后把下面代码保存到文件,代码如下:

<?php 
	$link=mysql_connect("localhost","root","12345"); //12345改成你的mysql密码 
	if(!$link) echo "失败!"; 
	//开源代码phprm.com 
	else echo "成功!"; 
	mysql_close(); 
	 

在浏览器打开 http://localhost/test.php

如果输入成功就说明你的配置成功了,如果失败我们可以在mysql_connect("localhost","root","12345") or die( mysql_error());这样就会有错误提示.

如果提示mysql_connect函数未定义,我们可以在php.ini中如下:

;extension=php_mysql.dll

;extension=php_mysqli.dll

把前面的;去了

extension=php_mysql.dll

extension=php_mysqli.dll

然后重启apache即可.
