[SOLVED] Quick question

[paulman888888]

If i use this gameid=$_GET['gameid'] and theres no gameid=something in the url what would be the value of it because i would like to make an IF statment.

 

If gameid=$_GET['gameid'] doesnt exist then $gameid=0 else gameid=$_GET['gameid']

 

How could i make that. thankyou for all the help

[trq]

<?php

  if (isset($_GET['gameid'])) {
    // do something.
  }

?>

[rhodesa]

$gameid = empty($_GET['gameid']) ? 0 : $_GET['gameid'];

 

I would recommend using empty or isset, because if the url is:

page.php?gamei=

then isset will still validate to true
