[PHP] Little question
Hi, Folks... I have this little snippet of code: Orario: It should print a little table with the string "MY STRING"... ... unfortunately, it doesn't. Any suggestion BTW: I run this code on the following configuration: PHP Version: 4.0.4pl1 MySQL API version: 3.23.22-beta Server API: httpd on a RHLinux 7.1 Thanks in advance Gabriele Biondo -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
Re: [PHP] Little question
This snippet should be used as an example of badly written and presented code. It tries too hard to do a simple job and in the result fails dismally. I suggest Gabrielle, that you try to be a little more careful in your coding and not so smart. I can find no less than four errors that I put down to poorly constructed code rather than poor syntax. As a hint, why are you trying to nest cals to PHP - your " Hi, Folks... > I have this little snippet of code: > > > > > >size="2"">Orario: > > > > It should print a little table with the string "MY STRING"... > ... unfortunately, it doesn't. > > Any suggestion > > BTW: I run this code on the following configuration: > > PHP Version: 4.0.4pl1 > MySQL API version: 3.23.22-beta > Server API: httpd on a RHLinux 7.1 > > Thanks in advance > > Gabriele Biondo -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
Re: [PHP] Little question
this :
if ... $myOra="" ...
should be more like :
if ... $myOra == "" ...
essentially you're setting $myOra as blank everytime which evaluates to
true, then it ends up printing the blank, which is not good. regarding
typos, this is a common one and since it reveals no error ... it can be
frustrating! :) you have others but this is the big one.

RE: [PHP] Little question
A good approach to prevent this is to always put your constants on the
lefthand side of the condition. This causes a parser error if you accidently
try and assign instead of compare. It takes a bit of getting used to, but
once you get into the swing of it you'll find it a useful tool in your
arsenal of weapons against accidental bugs.
So, the previous example would read:
if ... "" == $myOra ... <--- This is correct
whereas:
if ... "" = $myOra ... <--- This would cause a parser error, you'd
see the mistake immediately

Thanks!!! I was really naive!!! The other errors were all fixed (lots of them were caused by a Copy-paste operation from UE to OE...) Anyway you were really helpful Thanks a lot -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
