使用phpmailer发送电子邮件时调用Mail（）而不连接

Question

I am trying to send mail using phpmailer but it is giving error

<?php
   include("/mail/class.phpmailer.php");

    // Basic Header Input
    $mail = new PHPMailer();

    $mail->IsSMTP();
    $mail->Host = 'smtp.gmail.com';
    $mail->SMTPAuth = true;
    $mail->SMTPSecure = 'ssl';
    $mail->Port = 465;
    $mail->Username = 'username'; // your GMail user name
    $mail->Password = 'password';           //"Password";
    // ---------- adjust these lines ---------------------------------------

    $mail->From= '[e-mail]';
    $mail->FromName="My site's mailer";
    $mail->AddAddress("[e-mail]");
    $mail->Subject = "Your invoice";

    $mail->IsHTML(false);
    $mail->AddAttachment('test1.pdf', 'invoice.pdf'); // attach files/invoice-user-1234.pdf, and rename it to invoice.pdf
    $mail->Body = "Please find your invoice attached.";
    if(!$mail->Send())
    {
       echo "Error sending: " . $mail->ErrorInfo;;
    }
    else
    {
       echo "Letter is sent";
    }

?>
it is showing error like Error sending:

"Error sending: The following From address failed: [e-mail] : Called Mail() without being connected"

i try with adding code $mail->SMTPDebug = 1; then it is showing error like below

SMTP -> ERROR: Failed to connect to server: php_network_getaddresses: getaddrinfo failed: No such host is known. (0) The following From address failed: [e-mail] : Called Mail() without being connected

Answer 1

Change this,

$mail->From= '[e-mail]';

You are mixing single quotes and double quotes
