PHP实现查看邮件是否被阅读

 

<?

//当你在发送邮件时，你或许很想知道该邮件是否被对方已阅读。这里有段非常有趣的代码片段能够显示对方IP地址记录阅读//的实际日期和时间。

error_reporting(0);

Header("Content-Type: image/jpeg");

 

//Get IP

if (!empty($_SERVER['HTTP_CLIENT_IP']))

{

$ip=$_SERVER['HTTP_CLIENT_IP'];

}

elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR']))

{

$ip=$_SERVER['HTTP_X_FORWARDED_FOR'];

}

else

{

$ip=$_SERVER['REMOTE_ADDR'];

}

 

//Time

$actual_time = time();

$actual_day = date('Y.m.d', $actual_time);

$actual_day_chart = date('d/m/y', $actual_time);

$actual_hour = date('H:i:s', $actual_time);

 

//GET Browser

$browser = $_SERVER['HTTP_USER_AGENT'];

 

//LOG

$myFile = "log.txt";

$fh = fopen($myFile, 'a+');

$stringData = $actual_day . ' ' . $actual_hour . ' ' . $ip . ' ' . $browser . ' ' . "\r\n";

fwrite($fh, $stringData);

fclose($fh);

 

//Generate Image (Es. dimesion is 1x1)

$newimage = ImageCreate(1,1);

$grigio = ImageColorAllocate($newimage,255,255,255);

ImageJPEG($newimage);

ImageDestroy($newimage);

 

?>
