未被捕获的错误：找不到类'PHPMailer'

Question

我知道有很多关于此的线程，但我无法使其工作，我已经尝试了一切！ phpmailer下载没有autoload.php，我被卡住了。

请帮助，即使我已经链接了所需的文件，此错误“class”phpmailer'not found“不断出现。 Xampp正在运行。所有的邮件文件都在PHPMailer文件夹内（它包含文件夹src /，里面有5个我链接的文件）。提前致谢！

Answer 1

，而不是这样的：

//Create a new PHPMailer instance 
$mail = new PHPMailer(); 

使用本：

//Create a new PHPMailer instance 
$mail = new PHPMailer\PHPMailer\PHPMailer(); 

Answer 2

您必须安装作曲家 要安装见下面的链接中 http://webdevzoom.com/how-to-install-composer-on-windows/

运行这个命令你xampp的项目文件夹在cmd中（本地） “作曲家需要phpmailer/phpmailer”

然后你会在供应商文件夹中获得自动上传文件。 之后，你必须要加上“要求‘供应商/自动上传PHP的。’”你上面的代码..

然后根据要求.. 使用“的PHPMailer/PHPMailer的/ PHPMailer的”使用相应的文件; 使用'phpmailer/phpmailer/Exception';
