[SOLVED] $_GET[] and constants .. i.e. define()

[severndigital]

i have a list of errors and the codes to go with them in a constants.php file like this

 

define("P001","General Processing Error");

 

i want to issue the error code as part of the url for example

 

www.mysite.com/index.php?view=error&ecode=P001

 

how do I get my php code to recognize the ecode as a constant?

 

i could do it this way

 

if($_GET['ecode'] == "P001"){
   echo "<error>" . P001 . "</error>";
}

 

but i was hoping to not have to hard code the error number since i have quite a few of them.

 

I was thinking it would end up looking something like this:

 

if($_GET['view'] == 'error'){
echo "<error>" . some way to get php to see the ecode as constant . "</error">;
}

 

thanks in advance,

if($_GET['view'] == 'error'){
echo "<error>" . (defined($_GET['ecode']) ? constant($_GET['ecode']) : "Unknown Error") . "</error">;
}
