Upload the image from the php form to s3

It is necessary to make access right to s3 bucket beforehand with IAM.
Use php library to upload to s3. Here is code.

require 'vendor/autoload.php';

if(file_exists($_FILES['upfile']['tmp_name'])){
	$ext = substr($_FILES['upfile']['name'], strrpos($_FILES['upfile']['name'],'.') + 1);
	echo $ext."<br>";
	if(strtolower($ext) !== 'png' && strtolower($ext) !== 'jpg' && strtolower($ext) !== 'jpeg' && strtolower($ext) !== 'gif'){
		echo '画像以外のファイルが指定されています。画像ファイル(png/jpg/jpeg/gif)を指定して下さい';
		exit();
	}

	$tmpname = str_replace('/tmp/', '', $_FILES['upfile']['tmp_name']);
	echo $tmpname;
	$s3client = new Aws\S3\S3Client([
			'credentials' => [
					'key' => '',
					'secret' => ''
			],
			'region' => 'ap-northeast-1',
			'version' => 'latest',
	]);

	$result = $s3client->putObject([
			'Bucket' => 'zeus-image',
			'Key' => 'test.png',
			'SourceFile' => $_FILES['upfile']['tmp_name'],
			'Content-Type' => mime_content_type($_FILES['upfile']['tmp_name']),
	]);

}
