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

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

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.HttpRequest')
$req = new COM("Chilkat.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"
print 'verb = ' . $req->HttpVerb . "\n";
// The path will be "/watch"
print '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 - 1; $i++) {
    print $i . ') ' . $req->getParamName($i) . ': ' . $req->getParamValue($i) . "\n";
}

// View the request that would be sent if SynchronousRequest 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 SynchronousRequest is called.

print $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
// 
print $req->generateRequestText() . "\n";

// We can remove a parameter:
$req->RemoveParam('t');
print $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
// 
print $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
//    
//    --------------020906020106050705030807
//    Content-Disposition: form-data; name="v"
