Recently, I upgraded to PHP 5, then the following error messages start to appear, which did not appear before the upgrade:

Notice: Use of undefined constant keep - assumed 'keep' in c:\sites\ncirs\ncirs.php on line 11

>>> 'Tis the code: $tpl=new nci_Template(".",keep);

Notice: Undefined variable: opt in c:\sites\ncirs\ncirs.php on line 13

Thank you.

$tpl=new nci_Template(".",keep);


Have you defined the constant keep using define()? Or, did you think keep is a string? In which case that should read $tpl=new nci_Template(".",'keep');

Notice: Undefined variable: v in c:\sites\ncirs\ncirs.php on line 13


You havn't defined these variables. Why are you comparing undefined variables? Are you sure that your script doesn't require register globals?

There are not error messages, these are warning/notices. Your previous PHP installation was giving the same notices, but since your error reporting was off, you were not seeing them.

In short, this is not a PHP5 problem.

error_reporting(E_ALL ^ E_NOTICE);
