    <button type="button" id="chnageHeaderbtn">change header</button>

Put in script 

$("#chnageHeaderbtn").click(function() { 
var prevUrlAddress='http://www.myfirsturl.com';
var chnageUrlAddress='http://www.myurl.com';

window.location.href =chnageUrlAddress;

});

  <html>
            <head>
        <script>
              function  myfunction(){
         // no variable needed for this logic

           //window.location.replace('the redirect path when button is clicked ')
           // example 
          window.location.replace('newsletter_tb.php');

            }
    </script>
            </head>
            <body>
            <div>

            <button type="button" onclick="myfunction()">change header</button>
            </div
            </body>
        </html>

  • Using javascript is best for this question

  • PHP is server side scripting language

PHP is server side so it is executed before the page/html is sent to the user. any user interactions are handled by Javascript in the browser. if you wish to change content when a user clicks a button the use javascript event handlers

<html>
<head>
</head>
<body>
<div>
<button type="button" onclick="changeStuff()">change header</button>
</div>
<script>
    function changeStuff(){
        //change header code
    }
</script>
</body></html>

function(){

    $var= $new;
    echo $var;

 echo $var;
}
Php is a server side language. You can use javascript like this or if you really want to use php you need to submit the form

With PHP you can try the following:

<form action="" method="post">
   <input type="hidden" value="t">
   <button>change header</button>   
</form>

Add the post check to see if the page is posted.

<?php

$var= "hello world";
$new= "i hate world";

if ( $_POST ) {
    $var= $new;
    echo $var;
} else {
    echo $var;
}

But my guess is that you're really looking for a JS way of doing it.
