php安装配置
IIS环境
我们以php安装目录c:\php为例，首先找到c:\php\sapi\php4ts.dll文件，拷贝到windows系统目录（WindowsXP中为%windows%/system32目录）。 在IIS中添加文件关联，将.php文件映射到c:\php\sapi\php4isapi.dll。 然后编辑c:\php\php.ini文件，通过查找功能找到register_globals字符串，修改等于号后面的Off为On，该设置将打开session功能。同理找到extension_dir选项，设置为c:\php\extensions，再找到session.save_path选项，设置为c:\tmp，你要保证该文件夹存在，如果不存在，就新建一个。并将php.ini文件拷贝到windows安装目录(%windows%)下， 重新启动系统，php网站就可以工作了
apache环境
打开httpd.conf
添加php类型：AddType application/x-httpd-php .php
设置php目录：ScriptAlias /php/ "D:/Apache Group/php-4.4.0-Win32/"
设置默认文档：DirectoryIndex index.html index.html.var index.php default.php 安装gd图形库
将%php%/extension目录下的php_gd2.dll拷贝到%windir%/system32/ 设置php.ini中;extension=php_gd2.dll ，将之前的分号去掉，保存php.ini 重新启动web服务器 调用phpinfo()函数，如果其中出现gd段设置信息，则表示安装成功

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.
