PHP method to check whether the email has been read_PHP tutorial

When you send an email, you may want to know whether the email has been read by the other party. Here’s a very interesting snippet of code that displays the actual date and time the record was read by the other party’s IP address.

Copy code The code is as follows:

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 . ' ' . $browser . ' ' . "rn";
fwrite($ fh, $stringData);
fclose($fh);

//Generate Image (Es. dimesion is 1x1)
$newimage = ImageCreate(1,1);
$grigio = ImageColorAllocate($newimage,255,255,255);
ImageJPEG($newimage);
ImageDestroy($newimage);

?>
