2. Find the item "Define SRVROOT" and change the value in quotation marks to Apache installation directory

# DirectoryIndex: sets the file that Apache will serve if a directory
# is requested.
#
<IfModule dir_module>
    DirectoryIndex index.html index.php index.htm
</IfModule>

4. Enable rewrite function: remove the "ා" in front of the following line of code

LoadModule rewrite_module modules/mod_rewrite.so

5. Add PHP support and PHP installation path at the end of the file

# php7 support
LoadModule php7_module "D:/php-7.4.2/php7apache2_4.dll"
AddType application/x-httpd-php .php .html .htm

# configure the path to php.ini
<IfModule php5_module> 
    PHPIniDir "D:/php-7.4.2" 
    AddType application/x-httpd-php .php
    AddType application/x-httpd-php-source .phps
</IfModule>

Install PHP

1. Open the PHP installation directory, copy php.ini-development, and then change php.ini-development to php.ini for saving
2. Open php.ini to modify the configuration, and find the directory where extension dir = ext is changed to extension dir = ext, for example
