Jquery Ajax PHP - Pass values from PHP script into Ajax Success function?

Question

I have a form that is submitted via Ajax to a PHP script. Inside the PHP script I do a few checks for swear words.

How would I pass a 'yes' or a 'no' back to jquery from the PHP script so I can display some feedback to the user on the front end? In other words, a 'Thank you', or a 'Don't Swear!'

Thanks

You can just echo "yes" or "no", and do some string comparison in the jQuery success function. You could also echo "true" or "false", eval the content of the response and use it as a boolean, or use JSON...

With JSON, the php will look like :

<?php

...

echo "{\"result\" : true}";

?>

The javascript :

$.getJSON('blabla.php', function(data) {
  if(data.result){
    alert("dont't swear!");
  }else{
    alert("good boy!");
  }
});
