Extract extra info from headers_sent

[undercloud]

headers_sent allows you to define a file and a line that has undesirable output, otherwise it is impossible to identify and correct the error, there is not enough of this and it is difficult to debug, but the edit is very small, but gives many possibilities, I hope this edit will fall into the main branch, thanks!

Please define on separate lines

I think what you need ... if not, please specify

[Xerkus]

@undercloud It is a new feature, please target develop branch. Also it needs tests to be accepted.

[Xerkus]

Try it like this:

$this->expectException(EmitterException::class);
$this->expectExceptionMessage('Unable to emit response; headers already sent');
$this->expectExceptionMessage(sprintf(
    'output started at %s:%d',
     __FILE__,
     __LINE__ + 3
));
ob_start();
echo 'Unexpected Output';
try {
    $this->emitter->emit($response);
} catch (\Throwable $e) {
    throw $e;
} finally {
    ob_end_clean();
}

Unfortunately, unsuccessfully ... I assume that sending headers is not called in the SAPI environment of tests, all my attempts at tests are unsuccessful ...
