PHP使用imap读取邮件内容,2018可用

本文以QQ邮箱为例,已验证可以成功读取邮件内容,这里用到一个类,如下。

PHP使用imap读取邮件内容,2018可用_第1张图片

调用代码示例

public function get($userId){
     set_time_limit(100);
     $mail = new Email();
     $connect = $mail->mailConnect('imap.qq.com', '143','****[email protected]', '授权码');
     if ($connect) {
	 $totalCount = $mail->mailTotalCount();
	 $list = $mail->mailList();
	
	for ($i = $totalCount; $i > 0; $i--) {
		$mailHeader = $mail->mailHeader($i);
		if($mailHeader['from'] == '***@***.com'){//邮件来源
			 
			 if ($mailHeader['seen'] == "U") { //未读 
			 
			       if($mail->getBody($i)){
			 	     //邮件内容
			        }
			       $subject = $mailHeader['subject']; //邮件标题
			   
			       $status = $mail->mailRead($i);
			  }
             else{
		   	   $mail->mailDelete($i);//删除已读
 			   }
		}
	}	
	
	$mail->closeMail();//关闭
}

网上有很多读取邮件的类,很多已经无法正常使用,还有些容易出现编码错误问题,这个版本是经过我测试可以正常使用的,但是其他的邮箱没有一一验证。
