PHP5 and "isset"

When "register globals" is set to "on," has anyone noticed if PHP
Version 5 affects the usage of "isset" or not?

For example, in a webpage form, should the following code:
if (!isset($ordern umber)) { $ordernumber = '123456'; }

....be changed to this:

if (!isset($orderi d) || $orderid==NULL) { $ordernumber = '123456'; }

Thanks!

Use empty() to be on the safe side.

Hi Ian, Thanks for help! The columns and variables are exactly matched so it shouldn't be the problem. Actually the original html and php files are pretty long. But I guess a more detailed script should help you diagnose the problem. The error message to the below script is: --------------------------------- call someoneDB Error: Warning: mssql_num_rows(): supplied argument is not a valid Sybase

Hello all, We are currently changing our web server and, in the process, updating PHP version from 4.3.0 to 4.3.5. The problem we've got is that our PHP applications generate errors saying that some of the variables are Undefined. I didn't use "if(isset($myVar))" to validate if a variable has been passed from a HTML form but instead "if($myVar)".

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>". The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed. This is as boiled down as I can make it.

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
