Exemplo #1 Exemplo da função getallheaders()
<?php
foreach (getallheaders() as $name => $value) {
echo "$name: $value\n";
}
?>it could be useful if you using nginx instead of apache
<?php
if (!function_exists('getallheaders'))
{
function getallheaders()
{
$headers = [];
foreach ($_SERVER as $name => $value)
{
if (substr($name, 0, 5) == 'HTTP_')
{
$headers[str_replace(' ', '-', ucwords(strtolower(str_replace('_', ' ', substr($name, 5)))))] = $value;
}
}
return $headers;
}
}
?>A simple approach to dealing with case insenstive headers (as per RFC2616) is via the built in array_change_key_case() function:
$headers = array_change_key_case(getallheaders(), CASE_LOWER);There's a polyfill for this that can be downloaded or installed via composer:
https://github.com/ralouphie/getallheadersBeware that RFC2616 (HTTP/1.1) defines header fields as case-insensitive entities. Therefore, array keys of getallheaders() should be converted first to lower- or uppercase and processed such.dont forget to add the content_type and content_lenght if your are uploading file:
<?php
function emu_getallheaders() {
foreach ($_SERVER as $name => $value)
{
if (substr($name, 0, 5) == 'HTTP_')
{
$name = str_replace(' ', '-', ucwords(strtolower(str_replace('_', ' ', substr($name, 5)))));
$headers[$name] = $value;
} else if ($name == "CONTENT_TYPE") {
$headers["Content-Type"] = $value;
} else if ($name == "CONTENT_LENGTH") {
$headers["Content-Length"] = $value;
}
}
return $headers;
}
?>
chears magno c. heckapache_request_headers replicement for nginx
<?php
if (!function_exists('apache_request_headers')) {
function apache_request_headers() {
foreach($_SERVER as $key=>$value) {
if (substr($key,0,5)=="HTTP_") {
$key=str_replace(" ","-",ucwords(strtolower(str_replace("_"," ",substr($key,5)))));
$out[$key]=$value;
}else{
$out[$key]=$value;
}
}
return $out;
}
}
?>warning, at least on php-fpm 8.2.1 and nginx, getallheaders() will return "Content-Length" and "Content-Type" both containing emptystring, even for requests without any of these 2 headers. you can do something like
<?php
$request_headers = getallheaders();
if(($request_headers["Content-Type"] ?? null) === "" && ($request_headers["Content-Length"] ?? null) === "") {
// probably a getallheaders() bug, not actual request headers.
unset($request_headers["Content-Type"], $request_headers["Content-Length"]);
}
?>
- might be a bug in nginx rather than php-fpm, i don't know. anyway a real request wouldn't leave them at emptystring
