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

$http = new CkHttp();

// Insert your AWS keys here:
$http->put_AwsAccessKey('AWS_ACCESS_KEY');
$http->put_AwsSecretKey('AWS_SECRET_KEY');

$bucketName = 'chilkat.ocean';

// User-defined metadata are name/value pairs, and are added to the HTTP request header.
// Header names must begin with "x-amz-meta-" to distinguish them from other HTTP headers.
// Note that Amazon S3 stores user-defined metadata keys in lowercase.

// For example, to add genus=Hippocampus, we do this:
$http->SetRequestHeader('x-amz-meta-genus','Hippocampus');

// Add a few more user-metadata key pairs.
$http->SetRequestHeader('x-amz-meta-species','big-belly seahorse');
$http->SetRequestHeader('x-amz-meta-habitat','shallow tropical and temperate waters');

$success = $http->S3_UploadFile($localFilePath,$contentType,$bucketName,$objectName);
