Demonstrates how to initialize an HTTP request object from a URL. Chilkat2 PHP

<?php

use Chilkat2\HttpRequest;

$req = new HttpRequest();

// Loads the HTTP request object from a URL
$req->SetFromUrl('https://www.youtube.com/watch?v=fAZdTchQePc&t=45s');

// The verb will be "GET"
echo 'verb = ', $req->HttpVerb, "\n";
// The path will be "/watch"
echo 'path = ', $req->Path, "\n";

// The output of this loop will be
// 0) v: fAZdTchQePc
// 1) t: 45s
$numParams = $req->NumParams;
for ($i = 0; $i < $numParams; $i++) {
    echo $i, ') ', $req->GetParamName($i), ': ', $req->GetParamValue($i), "\n";
}

// View the request that would be sent if HttpSReq is called.
// The HTTP request will be a GET that looks like this:
//
//     GET /watch?v=fAZdTchQePc&t=45s HTTP/1.1
//     Host: domain
//
// Note: The HOST header will automatically get filled in with the actual domain when HttpSReq is called.

echo $req->GenerateRequestText(), "\n";

// We can add additional params
$req->AddParam('artist', 'Richard Bona');
$req->AddParam('musicType', 'Jazz');
$req->AddParam('festival', 'Estival Jazz Lugano');
$req->AddParam('year', '2008');

// Now examine the request that would be sent
//
//     GET /watch?v=fAZdTchQePc&t=45s&artist=Richard%20Bona&musicType=Jazz&festival=Estival%20Jazz%20Lugano&year=2008 HTTP/1.1
//     Host: domain
//
echo $req->GenerateRequestText(), "\n";

// We can remove a parameter:
$req->RemoveParam('t');
echo $req->GenerateRequestText(), "\n";

// What happens if we change the request from a GET to a POST?
$req->HttpVerb = 'POST';
// The request will now look like this:
//
//    POST /watch HTTP/1.1
//    Host: domain
//    Content-Length: 93
//
//    v=fAZdTchQePc&artist=Richard%20Bona&musicType=Jazz&festival=Estival%20Jazz%20Lugano&year=2008
//
echo $req->GenerateRequestText(), "\n";

// What happens if we make it a multipart/form-data?
$req->ContentType = 'multipart/form-data';
// Now the POST looks like this:
//
//    POST /watch HTTP/1.1
//    Content-Type: multipart/form-data; boundary=------------020906020106050705030807
//    Host: domain
//    Content-Length: 545
