How to run a PHP file from ubuntu?

Question

How to run a php file from ubuntu platform in the localhost? I have also installed LAMP in my system. When I try to run the php file, in the browser, it says "The requested URL is not found-404 ERROR found". I do not know how to proceed with this. My php files are in the directory as shown here "/usr/var/html/a.php".

Answer 1

There are two options.

1. Access the php file through a local webserver(ie thru a local website). The web-server will deal with the requested php file. It will use either,

   • Inbuilt PHP module to interpret the php file, or

   • PHP through CGI (eg.CGI, FastCGI)
     
     If your apache(check if apache is running using service apache2 status!!) is set to the default configuration, this could be as simple as
     

     http://localhost/path/to/your.php
     

     Remember by default, the base directory for apache is /var/www/html/, so you need not include this in the url.

2. Use the php binary directly from a terminal.

      php /path/to/your/file.php
