• PHP url parameter and page include
• PHP url parameter and page include

I´ve been asked several times how to solve this problem.
Let´s say you have folder which stores files with the content of the pages.
You also have an index.php page from which you send requests via url to display a relevant page. See demo.

This tutorial explains one of the approaches this can be done.

Within your site´s root folder create a folder called pages. Inside of this folder create five pages and provide them with some content:

home.php
about_us.php
services.php
testimonials.php
contact_us.php

In the site´s root folder create file and give it a name of index.php.
Open index.php in any text editor and copy and paste the following content:

This piece of code contains the standard html page structure, some styling and navigation which will send a parameter via url. After the closing </p> tag type:

This simple code does the entire work.
First condition checks if there is a pg parameter passed via url and if it is not empty by using:

if condition isn´t true (else) then it includes the default, home page:

If condition is true than parameter is assigned to a variable:

and another condition checks whether the file with the value of the parameter exists in the pages folder:

if it does then this file is included on the page by using:

if file doesn´t exist then the message is displayed

This is one of many ways you can use include function to populate information from external files by selecting them using url parameter.
