First of all, we need to confirm whether you have installed Apache and PHP correctly. If you are not sure, you can check by following the steps below:

1. Check the Apache version

Open a terminal or command prompt and enter the following command:

apache2 -v

If you don't see the output, you need to install Apache and PHP. You can follow the steps below to install:

3. Install Apache on Ubuntu

Open the terminal and run the following command:

sudo apt update
sudo apt install apache2

4. Install PHP on Ubuntu

Open the terminal and run the following command:

sudo apt update
sudo apt install php libapache2-mod-php

After completing the installation, we can start to troubleshoot the "PHP file not found" problem.

5. Check the Apache configuration file

Open a terminal or command prompt and enter the following command to edit the Apache configuration file:

sudo nano /etc/apache2/apache2.conf

Check this file Does the end of the file contain the following lines:

<FilesMatch .php$>
    SetHandler application/x-httpd-php
</FilesMatch>

If not, add these lines to the end of the file.

6, Check the Apache module

Open a terminal or command prompt and enter the following command to enable Apache’s PHP module:

sudo a2enmod php7.4

Please note that you need to replace the version number with your PHP version number.

7. Check the PHP file path

Check whether your PHP file is located in the Apache Web root directory or the virtual host root directory. You can find your root directory with the following command:

sudo nano /etc/apache2/sites-available/000-default.conf
