Since I started using error_reporting(E_ALL), I havent found (in my opinion) a good way to declare GET and POST variables when getting them from a form or querystring. I have searched google and the docs for several hours now without much luck.
<?php error_reporting(E_ALL); // This line stops the error reporting, else I get - Notice: Undefined index: i in..... $HTTP_GET_VARS["i"]="";
if ($HTTP_GET_VARS["i"] == "") { include("myfile.php"); } ?>
Is there a better way? I have tried var $i (only for classes I've discovered) settype($i, "integer")
Thanks in advance.
isset() is your friend.
if(isset($HTTP_GET_VARS['i']) && $HTTP_GET_VARS['i'] == '')
{ include('myfile.php'); }This will not trigger any warning, even under E_ALL.
In response to some of the other posts, developing at E_ALL is a good idea as it'll help you spot potential problem areas.
Also, even though you have a form element defined, it may not always appear in $HTTP_GET_VARS/$_GET (post, etc). One example are checkboxes. If no boxes are checked, the variable is never created and this is the way to check.
