How to ignore undefined variable error in PHP

Question

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

Need to shut off/lower the error checking either in the php.ini or using [error_reporting](http://php.net/manual/en/function.error-reporting.php) -- though you should be defining your variables before using them. ;p — Brad Christie, Feb 21 '11 at 01:23

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. – Spechal May 14 '18 at 21:56

I give an alternative answer, as you can see in my begining of answer I still suggest to use error_reporting – antoniputra May 16 '18 at 02:30

It doesn't deserve downvotes because I just learned something new from this :) – usernotnull Apr 21 '20 at 12:29

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.

You can set notices to not show.

error_reporting(E_ALL & ~E_NOTICE)

You should be developing with

error_reporting(E_ALL | E_STRICT)
