Use PHP constants in Javascript Ajax

Question

i'm new to web and facing issue while using PHP file's constants inside javascript Ajax call.

My PHP code in constants.php file is as:

<?php

$color = 'green';
define ('BASE_URL', 'https://example.com?');
define ('APP_KEY', 'abcde');
define ('USER_KEY', '12345');
?>

My Ajax call in another login.php file is as:

<script type="text/javascript" charset="utf-8">
$(document).ready(function() {

$("#loginPopup").on('click',function(){

    var x = document.forms["login"]["emailId"].value;
    var pwd = document.forms["login"]["pwd"].value;

    $.ajax({
    type: 'GET',
    url: 'BaseURL?appkey=abcde&userkey=12345&email='+ x +'&password=' + pwd,
    crossDomain: true,
    dataType: 'jsonp',

    success: function (response) {
        showAlert(response);
    },
    error: function (request, status, error) {
        alert("ERROR");
    }
});
});
});
</script>

I want to move constants i.e. Base URL, Keys etc to constants file. So i've created constants.php. But now, i don't know how to use that inside ajax call. Please help. Thanks in anticipation.

Change This url: ' <?php echo BaseURL ?>?appkey=abcde&userkey=12345&email='+ x +'&password=' + pwd, Also needs to include constant file in login.php — Priyank

Like so, assuming the two files are in the same dir:

<?php
require_once('constants.php');
?>

<script type="text/javascript" charset="utf-8">
$(document).ready(function() {

$("#loginPopup").on('click',function(){

    var x = document.forms["login"]["emailId"].value;
    var pwd = document.forms["login"]["pwd"].value;

    $.ajax({
    type: 'GET',
    url: '<?php echo BASE_URL  ?>?appkey=<?php echo APP_KEY  ?>&userkey=<?php echo USER_KEY  ?>&email='+ x +'&password=' + pwd,
    crossDomain: true,
    dataType: 'jsonp',

    success: function (response) {
        showAlert(response);
    },
    error: function (request, status, error) {
        alert("ERROR");
    }
});
});
});
</script>
