This is due to different setting in error reporting, now you have also
E_NOTICE turned on.
if($_GET['section']=='')
should be coded as:
if(empty($_GET['section']))
If GET variable 'section' is not sent, it is not equal to '', it does
not even exists, is undefined. Using it triggers error of level E_NOTICE.
If you write
$_GET[section]
php is looking for constant named 'section'. However, it does not
exists, so an error of level E_NOTICE is triggered. Undefined constant
is then converted to string with its name. So you get $_GET['section']
in the end.
It's a good practice have full error reporting turned on, since this
will help you spot errors and write safer code.
