Send php response to ajax

        <?php         if ($success){             $result = array("status" => "1");             echo json_encode($result);            }            else{              print "<meta http-equiv=\"refresh\" content=\"0;URL=/404.html\">";            }            ?>        <script>        jQuery(document).ready(function() {          $.ajax({                           type: 'GET',                           url:  'Thatscriptsomething.php',                           cache: 'false',                           dataType: 'json',                           success: function(response) {                               if(response.status == "1") {                                    alert("we having a working script");                               } else {                                    alert("Oops, script is a no go");                               }                            }                        });        });        </script>

Basic example - it works for me

PHP RESPONSE

$value =  array('msg' => 'true' );          echo json_encode($value);

AJAX METHOD

 $.ajax({    type: 'post',    url: 'URL',    contentType: false,  processData: false,  dataType:'JSON',  data: formData,      success: function(value) {                if (value.msg ==  'true') {                      //your action                }else{                      //your action                }      }});
