PHP readfile() Function – file handling

PHP readfile() Function – file handling

The readfile() function reads a file and writes it to the output buffer.

Assume we have a text file called “blog.eduguru.txt”, stored on the server, that looks like this:

The PHP code to read the file and write it to the output buffer is as follows (the readfile() function returns the number of bytes read on success):

<?php
echo readfile(“blog.eduguru.txt”);
?>

Output:

“Hi, This is a test file. This is created to show the example of readfile function in php.”
