Description:
------------
From documentation I would assume that making a HTTP request with 
"ignore_errors" context option I should always get response body no matter the 
HTTP response code server sent back. This seems to work for just some of the 
response codes (like 404) and will fail with others - "400 Bad Request" for 
example.

This affects fopen() and file_get_contents() as far as I have tested.

An ideal solution would be to:

- if fopen() is called with HTTP context and "ignore_errors" - return a valid 
resource (currently it will return false with a E_WARNING). Next calling 
stream_get_contents() on this resource should return response body. If 
"ignore_errors" is not set - behave the old way - keeping backwards-
compatibility.

- if file_get_contents() is called with HTTP context and "ignore_errors" - 
return response body no matter HTTP response code. Otherwise - keep old 
functionality for backwards compatibility.

Because of this bug writing an API client with HTTP streams is somewhat of  
challenge (or not possible at all).

Sorry, but your problem does not imply a bug in PHP itself.  For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system is not the
appropriate forum for asking support questions.  Due to the volume
of reports we can not explain in detail here why your report is not
a bug.  The support channels will be able to provide an explanation
for you.

Thank you for your interest in PHP.

You are doing something wrong.

/errors.php:
<?php
$errorcode = $_GET["errorcode"];
header("HTTP/1.0 $errorcode foobar");

echo "This is the content of $errorcode";
?>

And executing:

<?php
$opts = array(
    "ignore_errors" => 1,
);

$context  = stream_context_create(array("http" => $opts));
foreach(range(200, 404) as $errorcode) {
    $content = file_get_contents("http://localhost/errors.php?
errorcode=$errorcode", false, $context);
    echo $http_response_header[0], " - ", $content, "\n";
}
?>

Gives me:
