If you have a file, and you want to read the entire file into a single string, you can use the file_get_contents() function. It opens the specified file, reads all characters in the file, and returns them in a single string. Here is a PHP script example on how to file_get_contents():

<?php

$file = file_get_contents("/windows/system32/drivers/etc/services");

print("Size of the file: ".strlen($file)."n");

?>

This script will print:

Size of the file: 7116
