How? Look in php.ini for error_reporting. With it enabled if you try to use a variable without assigning a value to it it will generate a notice. There are a lot of situations this won't cover, but it covers more than having it disabled. -Stut -- http://stut.net/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Well, I am not aware of such php.ini variable, but I may recomment to increase your error level and you will be warned when you use uninicialized variable. -- Best regards, Daniel Gerzo -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I think you'll find they get assigned the value of null, not false. There is no setting that enforces such a requirement, but you can get some of the way there by enabling the display of notices which will tell you whenever a variable is used without being initialised. -Stut -- http://stut.net/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

No. There is a parameter in php.ini that tells you when you USE an uninitialized variable, however. error_reporting = E_ALL E_ALL includes E_NOTICE which is off by default which is just plain daft, if you ask me... -- Some people have a gift link here.

RE: [PHP] php as default value in html
When someone pulls up a form and fills it out, they subsequently submit that form.
