Chilkat PHP Downloads PHP Extension for Windows, Linux, MacOS, Alpine Linux, Solaris

<?php

// The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number.
// For example, if using Chilkat v9.5.0.48, then include as shown here:
include("chilkat_9_5_0.php");

// This example assumes Chilkat HTTP to have been previously unlocked.
// See Global Unlock Sample for sample code.

$http = new CkHttp();

$req = new CkHttpRequest();
$req->put_HttpVerb('POST');
$req->put_ContentType('multipart/form-data');
$req->put_Path('/v2.7/me/photos');

// Use the previously obtained access token.
// Note: The publish_actions scope is required to upload a photo.
$req->AddHeader('Authorization','Bearer FACEBOOK-ACCESS-TOKEN');

// Send an "Expect: 100-continue" header in the request.
// This causes the HTTP server to end a 100-continue response
// immediately after receiving the HTTP header.  The client
// (Chilkat) will receive this intermediate response, and if
// it's not an error response, it knows that the HTTP server will
// accept the data that is forthcoming.
// The alternative is to get an error response after trying to upload
// the entire contents of the files.
$req->AddHeader('Expect','100-continue');

// Set a photo caption.
$req->AddParam('caption','Here are some penguins!');

// Additional parameters can be added to the request by 
// calling AddParam once per parameter.  
// See https://developers.facebook.com/docs/graph-api/reference/user/photos
// for more information about other optional parameters.

// Indicate the local file to be uploaded.
$success = $req->AddFileForUpload('source','qa_data/jpg/penguins2.jpg');
if ($success != true) {
    print $req->lastErrorText() . "\n";
    exit;
}

// Upload the image file..
// resp is a CkHttpResponse
$resp = $http->SynchronousRequest('graph.facebook.com',443,true,$req);
if ($http->get_LastMethodSuccess() != true) {
    print $http->lastErrorText() . "\n";
    exit;
}

// Examine the response body:
$responseJson = $resp->bodyStr();
print $responseJson . "\n";

// The response contains JSON, such as this:
// {"id":"10210224963435862","post_id":"10224048320139890_10210224963435862"}
