Difference Between PHP Redirect and Fake Static

What is pseudo-static

Pseudo-static is relative to the real static
Pseudo-static just changes the URL to a static form, but it is still a dynamic web page in reality
The pseudo-static has the same SEO as the real static

What is redirection (very common, important to study)

Redirect the network request to a new direction, to another location
It is divided into internal and external, the difference is that when performing external redirection, the URL in the browser address bar will change
HTTP originally supports redirection3XX
Use redirection technology to implement pseudo-static

Redirection environment setup

Install web server (apache/nginx)
Load mod_rewrite.so module

Redirection implementation methods (mainly3）

Through configuration of WEB server main configuration <DIRECTORY> (production environment)
Through .htaccess (development environment)
Through script implementation (external redirection)

.htaccess redirection implementation steps

First step: Configure allowOverride All in the apache main configuration file (restart)
Second step: Configure in the .htaccess file

RewriteEngine on 
RewriteRule ^(.*)\.html$ $1.php  //Match HTML to PHP

RewriteEngine on 
RewriteRule ^(.*)\.html$ $1.php  //Match HTML to PHP
