Change a variable from its url

[didz666]

Im still learning how to use php so sorry if this is a stupid question.

 

Is it possible to change a variable in a php using its url when calling it using ajax.

<?php
$variable   = '1';  //can i change it via the url to 2
?>

<script>
   $.ajax({
     type: 'POST',
     url: "http://mysite.co.uk/myphp.php?$variable=1",
     success: function (data){
     $("$mydiv").html(data);
      }
   });
</script>

any help would really be apreciated.

 

thanks

Yes, for url variables you use the $_GET superglobal.

$variable = $_GET['your_url_var_name'];

// If the value is supposed to be a integer only, this is best for security
$variable = (int)$_GET['you_url_var_name'];
