(PHP ActiveX) Send HTTP POST using non-UTF8 such as Windows-1250

Demonstrates how to specify the character encoding (charset) to be used for the body of an HTTP POST.

Chilkat ActiveX Downloads ActiveX for 32-bit and 64-bit Windows Note: The php_com_dotnet.dll may need to be enabled inside of php.ini.

<?php

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Http')
$http = new COM("Chilkat.Http");

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.HttpRequest')
$req = new COM("Chilkat.HttpRequest");

// Load a JSON file containing strings with Polish chars.
// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.JsonObject')
$json = new COM("Chilkat.JsonObject");
$success = $json->LoadFile('qa_data/json/has_polish_chars.json');
if ($success == 0) {
    print $json->LastErrorText . "\n";
    exit;
}

// Add the request params expected by the server-side:
$req->AddParam('tytul',$json->stringOf('tytul'));
$req->AddParam('tresc',$json->stringOf('tresc'));

// Indicate we wish to explicitly send the charset attribute in the HTTP request header.
$req->SendCharset = 1;

// Send the POST
// You can send the POST to the URL below.  It will respond with the request body in quoted-printable format.
// Using quoted-printable, we can easily see the binary bytes for the accented chars.

// resp is a Chilkat.HttpResponse
$resp = $http->PostUrlEncoded('https://www.chilkatsoft.com/echoPost.cshtml',$req);
if ($http->LastMethodSuccess != 1) {
    print $http->LastErrorText . "\n";
    exit;
}

print $http->LastHeader . "\n";
print $resp->BodyStr . "\n";

// Sample output:

// --------------------------------------------------
// POST /echoPost.cshtml HTTP/1.1
// Host: www.chilkatsoft.com
// Content-Type: application/x-www-form-urlencoded; charset=utf-8
// Content-Length: 79
// 
// <pre>tytul=3DPrzyk%C5%82ad&amp;tresc=3DPrzyk%C5%82ad
// %82oszenie</pre>
// --------------------------------------------------

// We can see by the %C5%82 that utf-8 was sent, because %C5%82 is the 2-byte representation of a particular Polish char.

// -----------------------
// However.. we can change the charset used for the HTTP request by specifying the request object's charset.

$req->SendCharset = 1;
$req->Charset = 'windows-1250';

// resp is a Chilkat.HttpResponse
$resp = $http->PostUrlEncoded('https://www.chilkatsoft.com/echoPost.cshtml',$req);
if ($http->LastMethodSuccess != 1) {
    print $http->LastErrorText . "\n";
    exit;
}

print $http->LastHeader . "\n";
print $resp->BodyStr . "\n";

// Sample output...
// You can see how the bytes used for the Polish chars are now 1-byte per char (i.e. using Windows-1250) 

// --------------------------------------------------
// POST /echoPost.cshtml HTTP/1.1
// Host: www.chilkatsoft.com
// Content-Type: application/x-www-form-urlencoded; charset=windows-1250
// Content-Length: 70
// 
// <pre>tytul=3DPrzyk%B3ad&amp;tresc=3DPrzyk%B3ad
// e</pre>
// --------------------------------------------------
