What does this error mean?

[EchoFool]

Error Level: 8

Error Message: Undefined index:  register

Error File: index.php

Error Line: 114

Error Context: Array

 

The line 114 is: 

if($_GET){}else{   echo hi; }

 

I thought this was perfectly fine syntax to check if a GET of any kind is set yet i get this error in my logs which is very odd.

 

Any ideas?

You sure this is line 114 from index.php?

if($_GET){}else{   echo hi; }

I see no point in having that line of code as the $_GET superglobal variable will always be defined as an empty array, whether there isn't any query string variables being passed to the script.

Well the idea is to hide a DIV when any type of GET is set and it does work according to the page - the div hides when any GET is set but then this error occured at the same time even though it worked.

 

Would the isset work ? Or would that require a specific GET['name'] because of again the array issue?

 

And yes that is currently the test script - stuff before the line 114 is html output stuff

A better approach would be to check whether the variable $_SERVER['QUERY_STRING'] is empty

// nothing in the query string. Show the div
if(empty($_SERVER['QUERY_STRING']))
{
     echo '<div>whatever</div>';
}
