phpmyadmin的使用
我刚学php，想使用phpmyadmin，可访问时显示
phpMyAdmin - 错误
缺少 mysql 扩展。请检查 PHP 配置。 
我试着按此方案解决：
缺少mysqli扩展 的解决办法
1.检查php.ini ;extension=php_mysqli.dll是不是已经启用
2.检查php.ini extension_dir 地址是不是指向了php目录的ext目录下
3.检查lib_mysql.dll有没有拷贝到windows目录下
4.检查php安装目录ext目录下，php_mysqli.dll文件是不是存在
5.查看php详细页面,看看mysql和mysqli是不是已经启动
但是还是一样的错误，请大侠帮帮忙，小弟这里有礼了
回复讨论(解决方案)
所有项目检查正常？还是有不正常已经修正？还是提示错误?
自己写个 mysqli测试一下链接数据库看看是否也提示出错?
1、检查 phpinfo() 返回的页面中是否存在 mysql 或 mysqli
2、若没有，去掉 php.ini 中 extension=php_mysql.dll 或 extension=php_mysqli.dll
前面的分号。保存后重新启动 apache 。回到第一步
3、若还没有，查看 Loaded Configuration File 的值是否是你修改的文件，若不是则对正确的文件进行第二步
谢谢楼上的朋友及时回复，不过问题还是没解决，我不知道
查看php详细页面,看看mysql和mysqli是不是已经启动
这句的意思，如何确认是不是启用，搜索mysql可以查到，但是不是独立存在，是与别的词通过下划线连接，
而mysqli不存在
请朋友再帮忙解释解释，谢谢

那就是基本问题了，mysqli并没有正常的安装好.重新根据你自己写的那些步骤进行修正吧
《学习 PHP&MYSQL》里面有专门讲的
九转回肠，终于把问题解决了，原来是因为没有为php配置环境变量，找问题方向不对大吃苦头啊
谢谢楼上的朋友们多多帮忙

Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1?
Apr 17, 2025 am 12:06 AM
In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.
