How do I read a file from a destination to variable?

Question

I am trying to read a file's content, while doing something like this

$con="HDdeltin";
$fp = fopen($_SERVER['DOCUMENT_ROOT']. "/HDdeltin/Users/$con", "r");
echo $fp;

It doesn't return anything. What am I doing wrong?

Start with [the docs on `fopen()`](http://us3.php.net/manual/en/function.fopen.php). It returns a file handle from which you must `fread()` or `fgets()`. More likely, you wan t something simpler like [`file_get_contents()`](http://php.net/manual/en/function.file-get-contents.php). — Michael Berkowski, Jul 16 '14 at 13:45

fopen return a resource, not the text

Use file_get_contents($_SERVER['DOCUMENT_ROOT']. "/HDdeltin/Users/$con") instead

you can read by using this function

echo file_get_contents($_SERVER['DOCUMENT_ROOT']. "/HDdeltin/Users/$con");

Here is the example they provide:

// Read 14 characters starting from the 21st character
$section = file_get_contents('./people.txt', NULL, NULL, 20, 14);
var_dump($section);

So you will likely need to use

$fp = file_get_contents($_SERVER['DOCUMENT_ROOT']. "/HDdeltin/Users/$con", true);
echo $fp;

There are some differences between PHP versions it seems

<?php
// <= PHP 5
$file = file_get_contents('./people.txt', true);
// > PHP 5
$file = file_get_contents('./people.txt', FILE_USE_INCLUDE_PATH);
?>

Fast solution :

file_get_contents($_SERVER['DOCUMENT_ROOT'] . "/HDdeltin/Users/HDdeltin");

Use file_get_contents(), and you can prevent bad url with realpath().

$con = "HDdeltin";
$path = realpath($_SERVER['DOCUMENT_ROOT'] . "/HDdeltin/Users/$con");
echo file_get_contents($path);

To get current root, you can also use :
