PHP 5.3.0 连接mysqli出错的解决
近日因公司开发需要,在本机Win7下架设了Apache+MySql+PHP
所使用PHP版本:PHP5.3.0, 之后发现无法连接mysql数据库,均报超时错误:
PHP Warning: mysqli::mysqli(): [2002] A connection attempt failed because the connected party did not (trying to connect via tcp://localhost:3306) in xxx.php on line x
PHP Warning: mysqli::mysqli(): (HY000/2002): A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.
in xxx.php on line x
在网站上查找了很久,均没有有效的解决办法.
后来在国外的网上查到此原因与windows的hosts文件有关
对如下进行修改:
# 127.0.0.1 localhost
#:: 1 localhost
修改为
127.0.0.1 localhost
#:: localhost
问题解决

代码如下 echo session.save_path
打开浏览器查看竟然显示 sessionsave_path 不对啊，怎么会是这个呢，看� ......

GD库是PHP进行图象操作一个很强大的库。
先在php.ini里增加一行引用：extension=php_gd2.dll
重启apache。做一个测试页 var_dump(gd_info());输出数据表明GD库引用成功。
表单auth.html
<html>
<head>
<meta http-equiv='Content-Type' content='text/html; charset=utf-8'>
