[SOLVED] help making an if statement

[cs1h]

Hi,

 

I'm trying to make a if statement that does one thing when there is a GET variable present like this

www.somesite.com/index.php?thing=1234

 

and when no GET variable is there (like this

www.somesite.com/index.php

it does another thing.

 

I tried this but it doesn't work

<?php 
$switch = $_GET["c1"];

if($switch==" "){
echo "Hello Worker";
}else{ 
echo "Goodbye Worker";}


?>

 

Does anyone know how to do this?

 

Thanks,

Colin

if(empty($_GET['thing'])){
  echo "There is no GET value";
}else{
  echo "There is a GET value: ".$_GET['thing'];
}
