Reading Files in PHP

The function file_get_contents allows reading a file. The function takes the filename as a parameter and returns the text of that file as its result.

Let's see it in practice. Suppose we have a file index.php, which we access through the browser. Let also in this same folder there is a file test.txt.

Let's read the text of the text file and display this text on the screen:

index.php<?php
  echo file_get_contents('test.txt');
?>
