How to access a php variable in external php file using JavaScript?

Question

In www.example1.com/demo.php I have a variable named

$x=5

I want to display the value of $x in www.example2.com

How to do it?

www.example2.com does not have server-side language support. Can I do it with JavaScipt or does it have a another way to accomplish it?

Just send the param as a query parameter in the URL (www.example2.com?x=5) and fetch it in the new site using JS. Here's a post about that — M. Eriksson

javascriptWantValue.js :

// show the waiting circle gif animation ;
$("#waitingCircle").css("display", "block");

$.ajax({
    url: "getValueFromPhp.php?"+paramOptional,
    dataType: "text",
    async: true,
    success: makeuseofValueFromPhp
});

function makeuseofValueFromPhp(valueFromPhp, status123, XHR123) {

    console.log("value from php is : " + valueFromPhp);

    // hide the waiting circle ;
    $("#waitingCircle").css("display", "none");

}// end function makeuseofValueFromPhp()

getValueFromPhp.php is :

<?php
    $x = 5;
    echo $x;
?>
