搭建PHP开发环境
第一步，装apache
下载apache 的httpd-2.0.64-win32-x86-openssl-0.9.8o.msi到本地。 本来打算下新版2.2的，但是看页面上显示的是2.0的模块在2.2下可能会失效，所以就下得2.0的版本
然后配置文件httpd.conf
配置 DocumentRoot的为 我们网站的根目录。 DocumentRoot "E:/apache_Dir/docRoot"
配置 DirectoryIndex 就是apache先加载的网页文件。 DirectoryIndex homepage.php index.html index.html.var
第二步 安装PHP
从网站下得时php-5.2.17-Win32-VC6-x86.zip这个版本
然后还是修改apache的 httpd.conf配置文件
将php以模块的形式注册近apache 在173行附近
LoadModule php5_module E:/apache_Dir/php/php5apache2.dll
PHPIniDir "E:/apache_Dir/php"
首先在764行附近添加如下的类型映射
AddType application/x-httpd-php .php
AddType application/x-httpd-php .html
完成，我的php文件放置在E:/apache_Dir/docRoot目录下，以homepage.php命名

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.
How does PHP type hinting work, including scalar types, return types, union types, and nullable types?
Apr 17, 2025 am 12:25 AM
PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
