jQuery to load more content... Can't use .php file from a folder...?

Hi,
I have a jQuery script that automatically loads content from a mysql database through a .php script... I am still developing on XAMPP on Mac OS so all my files are in htdocs...

This is part of the script and it works perfectly fine if load.php is inside htdocs
$("#DIV").load("load.php",{"var":variable},function(){variable++;});

But I will be creating way more .php files to load content and I don't want them to be all in htdocs... So I placed them in a folder inside htdocs and now it's not working at all...

$(".F").load("content/load.php",{"var":variable},function(){variable++;});

Any idea how I can place all those .php files in a folder?
