无法使用xampp 5.6.3版发送gmail

Question

大家好我在使用Gmail发送邮件时遇到问题，当我在本地主机中打开sendmail.php时说“发送失败”

继承我sendmail.ini中的代码：

smtp_server=smtp.gmail.com

smtp_port=465

smtp_ssl=auto

error_logfile=error.log

debug_logfile=debug.log

auth_username=*******@gmail.com
auth_password=******

force_sender=*******@gmail.com 

的php.ini：

[mail function]

SMTP = smtp.gmail.com
smtp_port = 465
sendmail_from =*****@gmail.com
sendmail_path ="\"C:\xampp\sendmail\sendmail.exe\" -t"

mail.add_x_header =关

CODE：

    <?php
$to = '******@yahoo.com';
$subject = 'Test email'; 
$message = "Hello World!\n\nThis is my first mail."; 
$headers = "From: *****@gmail.com\r\nReply-To: *****@gmail.com";
$mail_sent = @mail( $to, $subject, $message, $headers );
echo $mail_sent ? "Mail sent" : "Mail failed";
?>
