The PHP function file_get_contents reads the entire contents of a file into a string, while the function file reads a file into an array.

file_get_contents('filename') is equivalent to implode('', file('filename')): 
<?php
// reads entire file into array, one element for each line, with
// newline still attached!
// The return value if FALSE upon failure.
$f = file("http://www.google.com/intl/en/contact/index.html");

// read entire file into a string.
$s = file_get_contents("http://www.google.com/intl/en/contact/index.html");

echo "implode('', file('...')) is equivalent to file_get_contents('...'): ",
     (implode('', $f) === $s), "\n";
?>
