Question

I have an AJAX request that fetches some info from a SQL database in PHP.

The problem is, I need to send it back to AJAX in variables. Not to just echo it all out on screen.

Is this possible? If so, how would I go about doing something like this?

Thanks.

Yes, you could json_encode the variable you want to send back to client.

echo json_encode( array('variable' => 'your value' ) ); 

The client will receive the data through a callback when the request is completed. Without more clarification on specifics that’s all i can offer, with some more details i can provide code samples depending on whether you’re using a JavaScript library such as jQuery or doing a raw XHR request.

Edit: so in jquery to retrieve the variable above you would do the following.

$.getJSON('yourfile.php', function(data){
      console.log( data.variable ); 
});
