Amazon AWSとPHPを使用して添付ファイル付きメールを送信する際にエラーが発生する

Question

Amazon AWSでPHPを使用してメールを送信する必要がありますが、単純なメールを送信できますがエラーが発生しました。毎回エラーが発生します。

Fatal error: Cannot redeclare Aws\constantly() (previously declared in /path/vendor/aws/aws-sdk-php/src/functions.php:20) in phar:///opt/lampp/htdocs/path/amazon/aws.phar/Aws/functions.php on line 22

私が使用したコード： -

require_once '/mypath/vendor/autoload.php'; 
include_once("SESUtils.php"); 

$subject_str = "Some Subject"; 
$body_str = "<strong>Some email body</strong>"; 
$attachment_str = file_get_contents("mypdf_file.pdf"); 

//send the email 
$params = 
    array("to" => "to@xyz.com", 
    "subject" => "Some subject", 
    "message" => "<strong>Some email body</strong>", 
    "from" => "from@xyz.com", 
    "replyTo" => "reply_to@gmail.com", 
    "files" => 
    array(
    "1" => array(
    "name" => "filename1", 
    "filepath" => "/path/to/mypdf_file.pdf", 
    "mime" => "application/pdf"

$res = SESUtils::sendMail($params);

Answer 1

私はconstantly()を再宣言については、このエラーを持っていた問題が解決されました私たちのコードでは、単に変更することによって：

include('/PATH/TO/aws-sdk-3/aws-autoloader.php'); 

このエラーメッセージをGoogleにあなたや次の人を助けるかもしれない

include_once('/PATH/TO/aws-sdk-3/aws-autoloader.php'); 

から

これは名前空間にすぎません。例を参照してください。名前空間クラスを使用するか、絶対に参照する必要があります。

use PHPMailer\PHPMailer\PHPMailer; 
use PHPMailer\PHPMailer\Exception; 

//Load composer's autoloader 
require 'vendor/autoload.php';
