HomeBackend DevelopmentPHP Tutorial php联接mysql出现空白页面,phpmyadmin配置后无法扩展到mysqli

php连接mysql出现空白页面,phpmyadmin配置后无法扩展到mysqli
配置环境如下。
apache_2.2.6
mysql server 5.5
php-php-5.2.3-win32
phpMyAdmin-3.4.3.2-all-languages
windows 32位
新手,初学php,学到要连接mysql了。出现问题, 搜索了网上所有方法都无解,有点挫败,软件都配置不好,接下来怎么走下去啊。

1.用语句测试连接sql。结果显示空白页,起初显示网页错误,mysql启动后,就只显示空白页了。
if($dbc=mysql_connect('localhost', 'username','password'))
    echo($dbc)

echo(Successfully connected to mysql!)


mysql_close();
}else{

echo(failed!)


2.phpMyAdmin 安装配置,起初打不开网页,后来发现应该把它放到存储我编写的php目录下,可是又显示 :缺少mysqli扩展。


这两样解决不了,我不知道怎么继续php学习下去。很烦恼。求高人指点。
首先,对于第一步,php的配置中,所有dll文件的复制,还有php.ini中的冒号去掉之类,我能确保没错了,都检查好几遍了。

第二布中,对于config.ini.php中的用户名,密码之类的改动,我也妥妥的没错了。
 可还是出这个问题啊 。求高人指点啊,我实在是无辙了。

  话说,你们当初是php新手时也遇到这么多问题咩?装个软件都不成功,太挫败一个誓学php的女生的积极性啦!

How do you loop through all the values stored in a PHP session?How do you loop through all the values stored in a PHP session?Apr 26, 2025 am 12:06 AM

In PHP, iterating through session data can be achieved through the following steps: 1. Start the session using session_start(). 2. Iterate through foreach loop through all key-value pairs in the $_SESSION array. 3. When processing complex data structures, use is_array() or is_object() functions and use print_r() to output detailed information. 4. When optimizing traversal, paging can be used to avoid processing large amounts of data at one time. This will help you manage and use PHP session data more efficiently in your actual project.
