Apache Shows PHP Code Instead of Executing It

Apache shows PHP code instead of executing it

You must enable php! Check the folder mods-enabled in the Apache directory (default: /etc/apache2/) to see if you find a file named php. I don't remember the extension but I think it's .so.

Also check in /var/log/apache2/error.log to see if you have any other errors.

PHP code is not being executed, but the code shows in the browser source code

Sounds like there is something wrong with your configuration, here are a few things you can check:

1. Make sure that PHP is installed and running correctly. This may sound silly, but you never know. An easy way to check is to run php -v from a command line and see if returns version information or any errors.

2. Make sure that the PHP module is listed and uncommented inside of your Apache's httpd.conf This should be something like LoadModule php5_module "c:/php/php5apache2_2.dll" in the file. Search for LoadModule php, and make sure that there is no comment (;) in front of it.

3. Make sure that Apache's httpd.conf file has the PHP MIME type in it. This should be something like AddType application/x-httpd-php .php. This tells Apache to run .php files as PHP. Search for AddType, and then make sure there is an entry for PHP, and that it is uncommented.

4. Make sure your file has the .php extension on it, or whichever extension specified in the MIME definition in point #3, otherwise it will not be executed as PHP.

5. Make sure you are not using short tags in the PHP file (<?), these are not enabled on all servers by default and their use is discouraged. Use <?php instead (or enable short tags in your php.ini with short_open_tag=On if you have code that relies on them).

6. Make sure you are accessing your file over your webserver using an URL like http://localhost/file.php not via local file access file://localhost/www/file.php

And lastly check the PHP manual for further setup tips.

PHP not interpreted, showing in view source

Are you sure you have php installed? If it is you need to make sure that apache is associating .php files with the php handler. Look for an entry similar to the following in /etc/apache/apache.conf

 LoadModule php5_module modules/libphp5.so

and

 application/x-httpd-php        php php5

upon changing the file you will need to restart apache via sudo service httpd restart

How do I prevent PHP displaying as plain text on my browser?

The title of your post is wrong. It should be something like "How to prevent My php code from displaying on the screen/browser".

Below are possible scenario.

If your PHP code is being shown in the browser, it implies that your server has not been setup to serve PHP scripts. Below are among few things you will need to do.

1.)PHP Xampp or Wamp Installation:. I prefer Xampp. First step is to ensure that PHP is installed and running correctly. You can download and Install Xampp if you have not done so.
An easy way to check if php is installed is to run php -v from a command line and see if returns version information or any errors

2.) Restarting your Server: If you have alter any files prior to this event, you will need to restart your server

3.) PHP File Extension Name: Ensure that you properly save your code as .php file extension name. Code save as .html or .txt will not be executable.

4.) In case if you are using Xampp. Ensure that your php files resides on htdocs folder if you are using xampp Eg

C:\xampp\htdocs\your-php-projects.

5.)Misconfiguration: This may be the last thing to check. But if you care about it, You can also check for misconfigurations.

For example: In Apache’s httpd.conf file, you will need to make sure that the line Eg as case may be "LoadModule php5_module" has been uncommented and that there is no semi-colon (;) at the beginning of the line.

Apache is downloading php files instead of displaying them

The correct AddType for php is application/x-httpd-php

AddType  application/x-httpd-php         .php
AddType  application/x-httpd-php-source  .phps

Also make sure your php module is loaded

LoadModule php5_module        modules/mod_php55.so

When you're configuring apache then try to view the page from another browser - I've had days when chrome stubbornly caches the result and it keeps downloading the source code while in another browser it's just fine.

How to make viewforum.php?foo=bar request serve a file instead of a PHP code?

Interesting problem indeed! force me to dig many Apache docs. In the end solution was simple i.e. to escape ? so that Apache doesn't treat ? and part after that as query string.

You may use this rewrite rule in your site root .htaccess:

RewriteEngine On

RewriteCond %{REQUEST_URI} ^/forum/viewforum\.php$ [NC]
RewriteCond %{QUERY_STRING} .
RewriteRule ^ %{REQUEST_URI}\%3F%{QUERY_STRING} [L,NC]

PS: \%3F is escaped ? so make Apache load /forum/viewforum.php?f=2&start=25 as a file.
