I recently setup a new web server and I'm getting undefined variable error. If I use variables without initializing, it gives me an error. The source code did not change. Only the LAMP environment did. How would you solve this problem?
Thanks

2Need to shut off/lower the error checking either in the php.ini or using error_reporting -- though you should be defining your variables before using them. ;pBrad Christie– Brad Christie2011-02-21 01:23:37 +00:00Commented Feb 21, 2011 at 1:23

you can change your error_reporting as people said, but if you want keep the default error_reporting configuration. you may use @ operator. e.g: @$post

Downvotes because you told someone to use error suppression.

I give an alternative answer, as you can see in my begining of answer I still suggest to use error_reporting
usernotnull
It doesn't deserve downvotes because I just learned something new from this :)

On the other hand, I know there may be some null or undefined value, and I am going to handle it below, but I do not want to supress other warning that I have not handled. It looks so clumsy to make checking with ` if (!isset(...) || !isset(...))` but
if (!$var0 || !$var1) looks much clearerYou can set notices to not show.
error_reporting(E_ALL & ~E_NOTICE)
You should be developing with
error_reporting(E_ALL | E_STRICT)

Well...
You should define all your variables, those warnings are there for a reason, to make you code better. Undefined variables can easily lead to typo errors in variable names.
You can change the *error_reporting* level, above E_NOTICE to get rid of that, but it is highly unadvisable.
