Description:
------------
error_reporting() has synopsis

int error_reporting  ([ int $level  ] )

which suggests it can be called without any argument and I indeed saw such a call, but I have no idea what level is set then because the default value is not documented.

The level is optional and does not have a default value, though I 
suppose you could argue that the default is the current error_reporting 
level.

Whatever interpretation you like, this is not a bogus issue. The 
effect of calling error_reporting() is not documented.
 [2009-10-14 09:39 UTC] rquadling@php.net 
That's the point. There is no effect.

The return value is documented. Supplying the optional value sets the 
level to the supplied optional value.

The parameter of "level" also shows that the value you supply is the new 
level you want to set.

So. Everything covered.

error_reporting() will return the current level.
error_reporting(xxx) will return the current level and then set it to 
the supplied level.

Yet the synopsis reads "Sets which PHP errors are reported".
If this only happens in some cases, the synopsis is incorrect.
"Get the current error_reporting level, optionally changing it" 
might fix, but I'm sure there is a better modification to make 
things crystal-clear.

Could someone please fix the status?

This was reported in ticket #50548. The issue was solved since.
