Getting info from url

[richclever]

Hi,

I have a url that I need to get info from. If I have a page called

http://www.domainname.com/index.php?id=54

how do I get a php function running in this page to return the value of id (54). I need this value to query a database when I am in the page in question.

Thanks

Rich

<?php
  echo $_GET['id'];
?>

Will display your id value.

Thanks a lot, I knew it must be quite simple. Presumably I can put that into a variable with

<?php
$idvalue = $_GET['id'];
?>

Have you looked at the PHP manual at

http://www.php.net/

?

Read the section on variables <

http://www.php.net/manual/en/language.variables.php>

and the section on Varibles from Outside PHP <

http://www.php.net/manual/en/language.variables.external.php>

You can do this by escaping characters, removing tags, trimming the variables, etc.
