New Comment:
Instead of starting ethical discussions about how php error design works please keep in mind:
1) php has ever worked that way, no one had never had problems about it
2) between php 5 and 7 has been introduced a backward incompatible change, without documenting it
3) shops that do php hosting want to be like php itself "do the right thing" in a
pragmatic way,
if our clients/or use code from third parties that do messy things about error_reporting we want
all will work anyway in most cases without touching
their code, for example wordpress and plugins
we can't afford and it's a also bad for all if who hosts had review all the code of our
clients/third parties plugins etc...while switching from php 5 to 7
also keep in mind that, the already slow adoption of php 7, for hosting providers will slow more
before php 7 we had the option to "php_admin_value[error_reporting] = E_ALL & ~E_NOTICE
& ~E_DEPRECATED & ~E_WARNING & ~E_STRICT" and all was good in case of problems
4) if php want to introduce a new better way/design to handle errors a new separate mode can be
added but should be optional until all php code/devs in the
word will know about that
5) we are not switching to php7 because of this

The problem I see is that error_reporting is a somewhat more fundamental configuration option with
direct language integration. If you take your premise that php_admin_value should affect the
error_reporting() function one step further, you could also argue that the @ operator should become
ineffective if php_admin_value[error_reporting] is used (which I think would be quite the
disaster...)

The thing is, error_reporting is more than just an INI value. It has a much larger impact on PHP at
runtime than options like include_path do. And while include_path probably only needs to be set once
or twice in code, during an initialization phase, it's perfectly reasonable to change the
error_reporting value at any time in any number of circumstances.
If no changes to the error reporting level are allowed at all, what about the @ operator? Should
that be blocked because it temporarily suppresses the level entirely?
Perhaps a php_admin_value for error_reporting should be treated as more than just an immutable
number. Say, as a bitmask that is always ORed with a desired new value? That would guarantee errors
of a certain type are always visible while allowing code and libraries to opt into other types. I
think that would be a more common use case than needing to ensure a maximum level (ANDing) so code
would only be able to turn off error types - which is probably needed for specific situations that
could be addressed with careful use of @.

there is nothing questionable - php_value versus php_admin_value and the same for 'flag'
has a defined behavior no matter what value you want not get changed by a script, on my servers I
would use it to disallow idiots lower the reporting level to force them write clean code running
with E_ALL or go away

Please also note that using php_admin_value has only one meaning, preventing change to ini directive
at user level, and also using php_admin_value is not mandatory, so i really can't see the
questionable part of the discussion.
Sorry for being raw, but i'm in a bad mood, and i can't find better words, despite also
not knowing english very well

ok this is a huge problem/change that complicate hosting of php sites a lot,
i can explain the details but i've already tried and no one cared,
at least list it on the backward incompatible list of things between php 5 and 7
AND in the doc, because the doc still explain the behavior of php5 :|
