Why use @ before variable in PHP? [duplicate]

Answer 1

It's used to avoid the error notice.

Answer 2

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.

Answer 3

error control operator .. suppresses error messages ..

Answer 4

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

Answer 5

@ 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.
