How to access php variable in javascript using echo statement

Question

I am trying to redirect to same page i am on but with some variable. The code i have written here is simple to understand. In my project there are too many html lines lying between them.

<?php 
    $id = 11;
 ?>
 <?php 
    echo '<script> window.location.href = "index.php?id=$id"</script>';
  ?>

It should take me to same page with like "index.php?id=11" but it loads page as "index.php?id=". What i can do to over come this ?

see [global variables(https://www.php.net/manual/en/reserved.variables.globals.php) — Rojo, Oct 31 '19 at 18:59

single quoted strings do not expand vars (https://www.php.net/manual/en/language.types.string.php#language.types.string.syntax.single), check the Note.

Your example works this way:

<?php
    $id = 11;
 ?>
 <?php
    echo '<script> window.location.href = "index.php?id=' . $id . '"</script>';
?>
