New Comment:
NULL for the host will assume localhost (which is documented), so
mysqli_connect("localhost", $user, $pass)
mysqli_connect(NULL, $user, $pass)
are the same.
The only thing suspicious is
mysqli_connect("NULL", $user, $pass)
Are you absolutely certain that passing the string "NULL" gives you a working connection?
(And your system isn't resolving it to localhost.) The connection might be reused - what if you
don't connect successfully earlier?

Description:
------------
---
From manual page: http://www.php.net/function.mysqli-connect
---
$con=mysqli_connect("localhost","my_user","my_password","my_db");
var_dump($con); -> Return mysql object.
$conn = mysqli_connect(NULL, $user, $pass);
$conn = mysqli_connect('NULL', $user, $pass);
Return Same/old object given before. Not thrown false or error.
$conn = mysqli_connect('NULLTest', $user, $pass);
Return false
Test script:
---------------
$con=mysqli_connect("localhost","my_user","my_password","my_db");
var_dump($con); -> Return mysql object.
$conn = mysqli_connect(NULL, $user, $pass);
$conn = mysqli_connect('NULL', $user, $pass);
Return Same object given before. Not thrown false or error.
$conn = mysqli_connect('NULLTest', $user, $pass);
Return false
Expected result:
----------------
$conn = mysqli_connect(NULL, $user, $pass);
Should return false.
Actual result:
--------------
$conn = mysqli_connect(NULL, $user, $pass);
var_dump($con); -> Return mysql object.
