Hey there,

Every day I ran in some Problems wasting time to debug code, since the peoples are often using the error control operator (any software):

It would be nice to see a php.ini directive, e.g. "error_controll_operators = 1|0", to disable or enable the silencing of php errors. 

Another old report (see #14192) was closed by, referring to some extension and xdebug. But, as controll operators itself are in the core, i think there SHOULD also be the option to disable/enable it...?

Thanks alot

Test script:

Expected result:
Fatal error: Call to undefined function anyNonExistingFunction() in /root/test.php on line 3

Actual result:
Empty Output

You can use the PECL scream extension or Xdebug with the xdebug.scream option to 
disable the error suppression operator.

Actually the more I look into that the more I want this thing in the core, as an 
ini setting and an API to disable it.

Let move to analyzed and see what can be done for 5.4+1.

Any luck to make this possible?

Now my opinion about that changes since the report:
It does not make sense to use it in production environment, or am i wrong?

It is even not a parser token, but i realized a little script to remove these operators from php files.

This is certainly a controversial topic, and as such needs the RFC
process[1].  Anybody who is interested in this feature is welcome
to pursue it; for the time being, I suspend this ticket.
