How to disable deprecated warnings in runtime php?

Question

I want to supress warning from this trigger_error('Deprecated', E_USER_DEPRECATED); in runtime. From I have read I can use error_reporting(E_ALL & -E_USER_DEPRECATED & -E_DEPRECATED);. But that does not work. I tried if error_reporting works in general by using error_reporting(0). This works. What did I miss? I did not find another way to solve my problem. And did not notice that this way does not work for someone else.

My code which does not suppress deprecated warning:

error_reporting(E_ALL & -E_USER_DEPRECATED);
trigger_error('Deprecated', E_USER_DEPRECATED);

Php version: 7.0.14.

I think what you want is a tilde, try error_reporting(E_ALL & ~E_DEPRECATED); — Napoli

You have a syntax error in the value for error_reporting(). To exclude certain errors you need to use the tilde symbol ~ instead of the dash -:

error_reporting(E_ALL & ~E_USER_DEPRECATED);
//                      ^ this one
trigger_error('Deprecated', E_USER_DEPRECATED);
