@Matthew I get the feeling shaz knows what it does in general, just not why it would be used to prefix a variable.Phil– Phil2010-11-12 02:05:59 +00:00Commented Nov 12, 2010 at 2:05

This link is super useful because even after 14 years it's up to date - and it even holds information for the latest PHP 8+
@ is pure evil. It's not a good idea to use. You can find an explanation about it here.
It can cause massive debugging headaches because it will even suppress critical errors.

Actually wrong. If you define a custom error handler, you can still receive all messages despite the @ suppression operator. Therefore it's in fact preferable to e.g. isset() decoration.

Maybe so, but I've seen way more people use it without a custom error handler and have way too many headaches dealing with it.
It's used to avoid the error notice.

The only reason I can think of to use the error suppression operator before a variable would be to suppress E_NOTICE errors if the variable is undefined.
As others have mentioned, this is a bad idea. It's much better to actually deal with errors than ignore them.

If you want to avoid notices and warnings use @ sign before variable
