What is PHP?
PHP stands for Hypertext Preprocessor, and it is a server-side scripting language used for web development. It is mainly used for creating dynamic web pages and is compatible with various databases, such as MySQL, Oracle, and PostgreSQL. PHP can be embedded in HTML code and is usually used in combination with Apache server.
The Apache Server Doesn’t Show PHP Issue
Symptoms of the Problem
One of the most common symptoms of the issue is that when you try to run a PHP file on your Apache server, it shows you the actual PHP code instead of executing it. The browser displays the PHP code as a plain text file.
Possible Causes of the Problem
There could be several reasons why your Apache server doesn’t show PHP:
Possible Causes |
Description |
|---|---|
PHP is not installed on the server |
If PHP is not installed on your server, Apache cannot execute PHP scripts. |
Incorrect PHP settings in php.ini |
Incorrect settings in the PHP configuration file can cause PHP scripts not to run properly. |
Wrong file extension |
If the file extension of your PHP file is incorrect, Apache will not recognize it as a PHP script. |
Incorrect settings in Apache configuration files |
Apache needs to be configured to recognize PHP scripts. |
Solution to the Problem
The solution to the problem depends on the cause of the issue. Here are a few steps to help you resolve the issue:
Step 1: Check if PHP is installed
Check if PHP is installed on your server by running the following command in your terminal:
php -v
If PHP is not installed, you need to install it on your server.
Step 2: Check if PHP module is enabled
Run the following command in your terminal to check if the PHP module is enabled:
sudo apachectl -M | grep php
If the PHP module is not enabled, run the following command:
sudo a2enmod php7.x
Replace ‘x’ with the version of PHP you have installed.
Step 3: Check PHP configuration file
Verify that your PHP configuration file, php.ini, is correctly set up. Some common settings that need to be checked include:
- display_errors = On
- error_reporting = E_ALL
- short_open_tag = On
Step 4: Restart Apache server
After making any changes to the PHP configuration file or the Apache configuration files, restart your Apache server by running the following command:
sudo service apache2 restart
Step 5: Test your PHP file
Create a new PHP file and test if it runs by using the following command:
php /path/to/your/file.php
If everything works correctly, the PHP code in your file should execute without any errors.
