Description:
------------
with error_get_last() i wish there was some way to check the error_reporting level at the time that error was created (or perhaps at the time it was triggered?), in particular, i've been in a situation where i wanted to know if it was triggered in a statement prepended with the error-suppression operator (`@`) or not (which makes error_reporting 0 for the duration of the statement), but seems there's no easy way to check that (could read the source code and check if that specific line has `@` in it, but if it's a line with multiple statements, one could easily get a "false positive" by reading the wrong `@`, also the error-suppression-operator doesn't even have to be on the same line as the the statement it's suppressing, so..)

Test script:
---------------
<?php
unset($b);
@$a = $b;

var_dump(error_get_last());


Expected result:
----------------
array(5) {
  ["type"]=>
  int(2)
  ["message"]=>
  string(21) "Undefined variable $b"
  ["file"]=>
  string(9) "/in/olPd9"
  ["line"]=>
  int(3)
  ["error_reporting_level"]=>
  int(0)
}


Actual result:
--------------
array(4) {
  ["type"]=>
  int(2)
  ["message"]=>
  string(21) "Undefined variable $b"
  ["file"]=>
  string(9) "/in/olPd9"
  ["line"]=>
  int(3)
}

Using a custom set_error_handler should work for that purpose -- any reason not to do that?

Apart from that, this seems like a reasonable request.
