我在php5.5测试中没遇到这么慢的问题
如果删除stream_socket_enable_crypto然后测试，它就不会那么慢
有什么好方法可以解决吗
<?php
/**
* This example shows making an SMTP connection with authentication.
*/
//SMTP needs accurate times, and the PHP time zone MUST be set
//This should be done in your php.ini, but this is how to do it if you don't have access to that
date_default_timezone_set('Etc/UTC');
require '../PHPMailerAutoload.php';
//Create a new PHPMailer instance
$mail = new PHPMailer;
//Tell PHPMailer to use SMTP
$mail->isSMTP();
//Enable SMTP debugging
// 0 = off (for production use)
// 1 = client messages
// 2 = client and server messages
$mail->SMTPDebug = 2;
//Ask for HTML-friendly debug output
$mail->Debugoutput = 'html';
//Set the hostname of the mail server
$mail->Host = "smtp.qq.com";
//Set the SMTP port number - likely to be 25, 465 or 587
$mail->Port = 25;
//Whether to use SMTP authentication
$mail->SMTPAuth = true;
//Username to use for SMTP authentication
$mail->Username = "304906398@qq.com";
//Password to use for SMTP authentication
$mail->Password = "munftzonbxribjdf";
//Set who the message is to be sent from
$mail->setFrom('304906398@qq.com', 'First Last');
//Set who the message is to be sent to
$mail->addAddress('304906398@qq.com', 'John Doe');
//Set the subject line
$mail->Subject = 'PHPMailer SMTP test';
//Read an HTML message body from an external file, convert referenced images to embedded,
//convert HTML into a basic plain-text alternative body
$mail->msgHTML("测试邮件");
//Replace the plain text body with one created manually
$mail->AltBody = 'This is a plain-text message body';
//Attach an image file
//send the message, check for errors
if (!$mail->send()) {
echo "Mailer Error: " . $mail->ErrorInfo;
} else {
echo "Message sent!";
}
SMTPDebug，大约27秒。
