Question

How can I pass multiple variables between PHP files using jquery with json?
Ex:

$.post("example.php", {asdf:asdf, sdfg:sdfg}, function(data){

        $('section').html(data);
});

But instead of just using the .html function I want to retrieve multiple variables from the PHP file and then use them for .html on my page. I can’t just use data because that only outputs whatever PHP returns so to my understanding php can only return one thing in a form of an echo(), but how can I make it retrieve more than just that one variable? I think I have to use JSON but I have never used JSON before so I would appreciate it if someone could help me out.
Thanks.

You can return a JSON object from php ( Returning JSON from PHP to JavaScript? ). And then in your jquery you can acees it like this,

$.post("example.php", {asdf:asdf, sdfg:sdfg}, function(data){

 $('section1').html(data.Variable1);
 $('section2').html(data.Variable2);

});
