如何从目标读取文件到变量？

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?

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 :

• getcwd() function.
• dirname(__FILE__), you can get more here.
