Question

I want to call a PHP file using ajax where in that PHP i will place order by the ajax call. But it throws error while i am using app/Mage.php from that file

require_once '../../../../../../../../../../app/Mage.php';    
$customer = Mage::getModel('customer/customer');

then it says

Fatal error: Call to a member function getModelInstance() on a
non-object in app\Mage.php on line 432

Can anyone please help me???

Your proposed solution is not optimal. You have not initialized Magento so module XML is not loaded yet and the factory pattern does not work.

Simply use either:

Mage::init(); // 1.5+ 

or

Mage::app(); // (pretty much anything) below 1.5

before using getModel.
