我是 PHP 新手，我必須使用 phpmailer 發送簡歷。我發現錯誤為“Mailer Error: SMTP connect() failed. https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting ”。請更改代碼。我在我的代碼中使用 phpmailer。它在我第一次做的時候有效，但現在這段代碼會出錯。<?php include('header.php');require 'PHPMailerAutoload.php';$message='';if(isset($_POST["submit"])){   $path='upload/'.$_FILES["resume"]["name"];   move_uploaded_file($_FILES["resume"]["tmp_name"], $path);   $mail = new PHPMailer;$mail->SMTPDebug = 0;                               // Enable verbose debug output$mail->isSMTP();                                      // mailer to use SMTP$mail->Host = 'smtp.gmail.com';  // Specify main and backup SMTP servers$mail->SMTPAuth = true;                               // Enable SMTP authentication$mail->Username = '[email protected]';                 // SMTP username$mail->Password = 'mypasswordgoeshere';                           // SMTP password$mail->SMTPSecure = 'ssl';                            // Enable TLS encryption, `ssl` also accepted$mail->Port = 465;                                    // TCP port to connect to$mail->From=$_POST['email'];$mail->FromName=$_POST['name'];$mail->setFrom($_POST['email']);$mail->addAddress('[email protected]'); $mail->AddCC($_POST['name'],$_POST['email']);$mail->WordWrap=50;$mail->AddAttachment($path);$mail->Subject='application for job';    // Add a recipient              // Name is optional$mail->addReplyTo($_POST['email']);$mail->isHTML(true);                                  // Set email format to HTML//$mail->Subject = $_POST['subject'];$mail->Body    = $_POST['message'];$mail->AltBody = $_POST['message'];if(!$mail->send()) {    echo '<script>alert("Message could not be sent.")</script>';    echo 'Mailer Error: ' . $mail->ErrorInfo;} else {    echo '<script>alert("Message has been sent");        window.location.href="career.php";    </script>';}}?>
