model view controller - Including required files on AJAX requested PHP page -

recently started learning how set mvc model. built simple single page application develop skills. requires config files classes (using __autoload) included in index file.

my question: suppose want include ajax calls php pages need aforementioned config data and/or classes generate output. presume i'd have include required files on each , every ajax requested php page, or might there way take care of "globally"?

many support.

i dont know why need config ajax calls.

ajax same path calling other normal calls asynchron.

$.ajax({    url: "/path/", // or "yourphpfile.php"    type: "get", // or post    data: {data:data} }).done(function(){    alert("success, happy"); });  

you dont need config
