HTTP_RESPONSE_HEADER(3) 1 HTTP_RESPONSE_HEADER(3)
$http_response_header - HTTP response headers
The $http_response_header array is similar to the get_headers(3) function. When using the HTTP wrapper, $http_response_header will be pop-
ulated with the HTTP response headers. $http_response_header will be created in the local scope.
Example #1
$http_response_header example
<?php
function get_contents() {
file_get_contents("http://example.com");
var_dump($http_response_header);
}
get_contents();
var_dump($http_response_header);
?>
The above example will output something similar to:
array(9) {
[0]=>
string(15) "HTTP/1.1 200 OK"
[1]=>
string(35) "Date: Sat, 12 Apr 2008 17:30:38 GMT"
[2]=>
string(29) "Server: Apache/2.2.3 (CentOS)"
[3]=>
string(44) "Last-Modified: Tue, 15 Nov 2005 13:24:10 GMT"
[4]=>
string(27) "ETag: "280100-1b6-80bfd280""
[5]=>
string(20) "Accept-Ranges: bytes"
[6]=>
string(19) "Content-Length: 438"
[7]=>
string(17) "Connection: close"

string(38) "Content-Type: text/html; charset=UTF-8"
}

STREAM_GET_META_DATA(3) 1 STREAM_GET_META_DATA(3)stream_get_meta_data - Retrieves header/meta data from streams/file pointers
SYNOPSIS
array stream_get_meta_data (resource $stream)
DESCRIPTION
Returns information about an existing $stream.
PARAMETERS
o $stream
- The stream can be any stream created by fopen(3), fsockopen(3) and pfsockopen(3).
RETURN VALUES
The result array contains the following items:
o timed_out (bool) - TRUE if the stream timed out while waiting for data on the last call to fread(3) or fgets(3).
o blocked (bool) - TRUE if the stream is in blocking IO mode. See stream_set_blocking(3).
o eof (bool) - TRUE if the stream has reached end-of-file. Note that for socket streams this member can be TRUE even when
unread_bytes is non-zero. To determine if there is more data to be read, use feof(3) instead of reading this item.
o unread_bytes (int) - the number of bytes currently contained in the PHP's own internal buffer.
Note
You shouldn't use this value in a script.
o stream_type (string) - a label describing the underlying implementation of the stream.
o wrapper_type (string) - a label describing the protocol wrapper implementation layered over the stream. See "Supported Protocols
and Wrappers" for more information about wrappers.
o wrapper_data (mixed) - wrapper specific data attached to this stream. See "Supported Protocols and Wrappers" for more information
about wrappers and their wrapper data.
o mode (string) - the type of access required for this stream (see Table 1 of the fopen() reference)
o seekable (bool) - whether the current stream can be seeked.
o uri (string) - the URI/filename associated with this stream.
EXAMPLES
Example #1
stream_get_meta_data(3) example
<?php
$url = 'http://www.example.com/';
if (!$fp = fopen($url, 'r')) {
trigger_error("Unable to open URL ($url)", E_USER_ERROR);
}
$meta = stream_get_meta_data($fp);
print_r($meta);
fclose($fp);
?>
The above example will output something similar to:
