Deploying Codeigniter 4 Website on LAN server

Have you confirmed if you have properly installed the PHP module in your Apache? This is because instead of parsing the index.php as a PHP file, your server instead parses it as a normal text file resulting in just rendering the contents.

Make sure you have the following similar lines in your apache2.conf

Code:

# Taken from my dev httpd.conf
PHPIniDir "C:/php80"
AddHandler application/x-httpd-php .php
LoadModule php_module "C:/php80/php8apache2_4.dll"
