　apache configuration php environment

1. We install the apache environment on the computer,

　2. Then we download the php version and unzip it in the C: drive php directory

Then we add

immediately after apache

LoadModule php5_module "c:/php5/php5apache2_2.dll"

AddType application/x-httpd-php .php

PHPIniDir "c:/php5"

Restart apache and the configuration will be ready

Then we create a website and put the php file in the website directory to run it. The code is as follows

define("test","HELLO WORLD!");

echo test

Output is

HELLO WORLD

Friendly reminder, this article only briefly introduces what kind of file php is, and also attaches some ideas for opening php files and letting php run. Specifically, if we want to actually run php, we need to configure the apache environment in more detail. That’s okay, because the real application also requires the installation and configuration of the mysql database.
