Php fopen is not working through jquery ajax

[colap]

$("input.class_input_button_send").on("click",function(event) {

               event.preventDefault();

               //var username = $("input.class_input_hidden").val();

               var typed_text = $("input#id_input_text_type").val();

               console.log(typed_text);

               rt = $.ajax({

                    type: "POST",

                    url: "send.php",

                    data: { name: "", typed_text: typed_text },

                    success: function(data) {

                        console.log(data);

                        console.log(data.length);

                    }

                }).done(function() {

                    alert( "success" );

                    })

                  .fail(function() {

                    alert( "error" );

                });

               //console.log(rt);

           });

send.php =><?php

<?php

    if( session_id() == '' ) {

        session_start();

    }

    if($_SERVER['SERVER_PROTOCOL'] == "HTTP/1.1") {

        $domain_host_root = "http://" . $_SERVER['SERVER_NAME'] . "/";

    }

    require_once 'core/model/mysql/mysqldb.php';

    require_once 'core/utility/debug-app.php';

    require_once 'core/utility/utility.php';

    require_once 'core/view/view.php';

    

    //$_POST['typed_text'] = "abc";

    $typed_text = $_POST['typed_text'];

    $objDateTime = new DateTime('NOW');


    $target_file = $objDateTime->format("Y-m-d");

    $handle = fopen("archive/" . $target_file . ".txt", "w+");

    fwrite($handle, $target_file_data);

    echo json_encode($target_file);

?>

fopen function is working inside that send.php script if i run this as a standalone script, but fopen function returns null through the jquery $.ajax() function.

PHP-coder,

 

Add dataType: "json" to your function params.

$.ajax({dataType: "json",
url: url,
data: data,
success: success
});
