http_parse_headers — Parse HTTP headers
Parses HTTP headers into an associative array.
string containing HTTP headers
Returns an array on successIm Fehlerfall wird FALSE zurückgegeben..
Beispiel #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));
?>
Das oben gezeigte Beispiel erzeugt folgende Ausgabe:
Array
(
[Content-Type] => text/html; chatset=UTF-8
[Server] => Funky/1.0
[Set-Cookie] => Array
(
[0] => foo=bar
[1] => baz=quux
)
[Folded] => works
too
)
This one works 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]]) ) {
$retVal[$match[1]] = array($retVal[$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;
}
$headers = "HTTP/1.1 200 OK\r\n
Date: Tue, 08 Aug 2006 05:32:01 GMT\r\n
X-Powered-By: PHP/4.4.3-dev\r\n
Data 1: Value for Data 1\r\n
Data 2: Value for Data 2\r\n
Connection: close\r\n
Content-Type: text/html\r\n";
http_parse_headers($headers);
// OUTPUT:
array(7) {
["status"]=>
string(15) "HTTP/1.1 200 OK"
["Date"]=>
string(29) "Tue, 08 Aug 2006 05:32:01 GMT"
["X-Powered-By"]=>
string(13) "PHP/4.4.3-dev"
["Data 1"]=>
string(16) "Value for Data 1"
["Data 2"]=>
string(16) "Value for Data 2"
["Connection"]=>
string(5) "close"
["Content-Type"]=>
string(9) "text/html"
}
?>
