I made a small mistake in http://www.php.net/manual/en/function.http-parse-headers.php#112986
The line
<?php
$headers[0] = trim($h[0]);trim($h[0]);
?>
Should be changed to:
<?php
$headers[0] = trim($h[0]);
?>
http_parse_headers
(PECL pecl_http >= 0.10.0)
http_parse_headers — Parse HTTP headers
Description
array http_parse_headers
( string
$header
)Parses HTTP headers into an associative array.
Parameters
-
header -
string containing HTTP headers
Return Values
Returns an array on success or FALSE on failure.
Examples
Example #1 Using http_parse_headers()
<?php
$headers = "content-type: text/html; charset=UTF-8\r\n".
"Server: Funky/1.0\r\n".
"Set-Cookie: foo=bar\r\n".
"Set-Cookie: baz=quux\r\n".
"Folded: works\r\n\ttoo\r\n";
print_r(http_parse_headers($headers));
?>
The above example will output:
Array
(
[Content-Type] => text/html; charset=UTF-8
[Server] => Funky/1.0
[Set-Cookie] => Array
(
[0] => foo=bar
[1] => baz=quux
)
[Folded] => works
too
)

Taken from http://www.php.net/manual/en/function.http-parse-headers.php#112917 and modified to: make folded work too, return status in first key.
<?php
if (!function_exists('http_parse_headers'))
{
function http_parse_headers($raw_headers)
{
$headers = array();
$key = ''; // [+]
foreach(explode("\n", $raw_headers) as $i => $h)
{
$h = explode(':', $h, 2);
if (isset($h[1]))
{
if (!isset($headers[$h[0]]))
$headers[$h[0]] = trim($h[1]);
elseif (is_array($headers[$h[0]]))
{
// $tmp = array_merge($headers[$h[0]], array(trim($h[1]))); // [-]
// $headers[$h[0]] = $tmp; // [-]
$headers[$h[0]] = array_merge($headers[$h[0]], array(trim($h[1]))); // [+]
}
else
{
// $tmp = array_merge(array($headers[$h[0]]), array(trim($h[1]))); // [-]
// $headers[$h[0]] = $tmp; // [-]
$headers[$h[0]] = array_merge(array($headers[$h[0]]), array(trim($h[1]))); // [+]
}
$key = $h[0]; // [+]
}
else // [+]
{ // [+]
if (substr($h[0], 0, 1) == "\t") // [+]
$headers[$key] .= "\r\n\t".trim($h[0]); // [+]
elseif (!$key) // [+]
$headers[0] = trim($h[0]);trim($h[0]); // [+]
} // [+]
}
return $headers;
}
}
?>
Example:
<?php
$headers = "HTTP/1.1 200 OK\r\n".
"content-type: text/html; charset=UTF-8\r\n".
"Server: Funky/1.0\r\n".
"Set-Cookie: foo=bar\r\n".
"Set-Cookie: baz=quux\r\n".
"Folded: works\r\n\ttoo\r\n";
print_r(http_parse_headers($headers));
?>
The above example will output:
Array
(
[0] => HTTP/1.1 200 OK
[content-type] => text/html; charset=UTF-8
[Server] => Funky/1.0
[Set-Cookie] => Array
(
[0] => foo=bar
[1] => baz=quux
)
[Folded] => works
too
)

This one works even better:
<?php
function http_parse_headers( $header )
{
$retVal = array();
$fields = explode("\r\n", preg_replace('/\x0D\x0A[\x09\x20]+/', ' ', $header));
foreach( $fields as $field ) {
if( preg_match('/([^:]+): (.+)/m', $field, $match) ) {
$match[1] = preg_replace('/(?<=^|[\x09\x20\x2D])./e', 'strtoupper("\0")', strtolower(trim($match[1])));
if( isset($retVal[$match[1]]) ) {
if (!is_array($retVal[$match[1]])) {
$retVal[$match[1]] = array($retVal[$match[1]]);
}
$retVal[$match[1]][] = $match[2];
} else {
$retVal[$match[1]] = trim($match[2]);
}
}
}
return $retVal;
}
?>

If you don't have access to the PECL library, you can use this code to parse headers contained in strings.
Note that it's probably not as robust as the PECL version, as it only parses if the headers are separated by newlines (\n). This isn't a problem in most cases, though, as the standard suggests to use \r\n as the delimiter for headers.
HTTP response code is put into 'status'.
Any suggestions welcome!
<?
function http_parse_headers($headers=false){
if($headers === false){
return false;
}
$headers = str_replace("\r","",$headers);
$headers = explode("\n",$headers);
foreach($headers as $value){
$header = explode(": ",$value);
if($header[0] && !$header[1]){
$headerdata['status'] = $header[0];
}
elseif($header[0] && $header[1]){
$headerdata[$header[0]] = $header[1];
}
}
return $headerdata;
}
$headers = "HTTP/1.1 200 OK\r\n
Date: Tue, 08 Aug 2006 05:32:01 GMT\r\n
X-Powered-By: PHP/4.4.3-dev\r\n
Data 1: Value for Data 1\r\n
Data 2: Value for Data 2\r\n

Content-Type: text/html\r\n";
http_parse_headers($headers);
// OUTPUT:
