I would agree that performance-wise, there may be little difference in how fast a script runs. And for pre-defining variables, sure you can get away without doing that and php will happily help you out. However, I find it easier to debug my code knowing whether or not I remembered to assign a value to my variable and where the heck it got assigned from. :-)
I would also like to point out that the combo of not registering globals and having all errors reported will ensure you get the right data type when using the same variable names for _POST, _SESSION, et cetera data. I had a few scripts that behaved differently than I though because I was looking for the value of $foo and not realizing that my $foo was grabbing my session data instead of what I thought I was assigning it to. I changed my php.ini and now I tear out far less hair this way ;-) # Nathan ----- Original Message ----- From: "Maxim Maletsky (PHPBeginner.com)" <[EMAIL PROTECTED]> To: "'Nathan'" <[EMAIL PROTECTED]>; "'PHP'" <[EMAIL PROTECTED]> Sent: Thursday, April 25, 2002 12:18 PM Subject: RE: [PHP] Parse Error - Help? (AGAIN) You know, I once said the same: better fix the notices and keep the code "clean". But as I've done several performance tests I came to a conclusion that there's no much difference debugging the code yourself or let PHP doing it. Often predefining manually a variable resulted to me being even more 'expensive' then when PHP debugs it. I think it is wise using this feature of PHP. The only reason not to is for having the full control of your code.
