How to embed PHP inside the jquery script?

I need to copy the value of a jquery variable into a PHP variable.

My code:

<script>
$(document).ready(function() {
  var gtext = "Sample text";
  console.log(gtext); //I get the gtext printed in console     
  <?php   $variablephp = "<script>document.write(gtext)</script>" ?>
  <?php echo $variablephp; ?> // I cannot get printed this php variable       
  <?php echo "hi"; ?> //This echo statement not get printed
});
</script>

Can anyone please help on this?

My question is different in the sense I want to store a jquery value inside a PHP variable. Not a PHP variable into a jquery element.

This would be a jquery to php method

inside index.php

<button id="button1">Press Me</button>

<script type="text/javascript">
    $( "#button1" ).click(function() {
        $.ajax({
            method: "POST",
            url: "server.php",
            data: { name: "John", location: "Boston" }
        }).done(function( msg ) {

        });
    });
</script>

<?php
    //This will display the session data
    if(!empty($_SESSION)) {
        print '<pre>';
        print_r($_SESSION);
        print '</pre>';
    }
?>

inside server.php

<?php

session_start();

function cleanInput($string)
{
    return preg_replace("/[^A-Za-z0-9 ]/", '', $string);
}

if(!empty($_POST['name'])) {
    $_SESSION['name'] = cleanInput($_POST['name']);
}

if(!empty($_POST['location'])) {
    $_SESSION['location'] = cleanInput($_POST['location']);
}

Then after the user clicks the button, if they refresh the page the php $_SESSION will contain the new data

Okay. So Why I wanted to store the jquery value into a PHP variable is, I wanted the values I got in jquery as session variables in PHP.

Because I want these jquery values to be specific for each user.

Is there any other option in jquery itself, to behave this jquery value like a session variable in PHP?

Sorry if this is irrelevant, as I am new to all this.

You can use php like this :

<script>
  $(document).ready(function (e) {
    <?php if (isset($variable) && $variable !=''){ ?>
      var abc = 'this';
    <?php }else{ ?>
      var abc = 'that';
  });
</script>
