The Code for Tracing IP in PHP is as follows.

<?php

$image =imagecreate(1,1);
$colorblack=imagecolorallocate($image,0,0,0);
$colorwhite=imagecolorallocate($image,255,255,255);
imagefill($image,0,0,$colorwhite);

imagechar($image,1,0,0,”.”,$colorblack);
header(“content-type: image/jpeg”);
imagejpeg($image);

$to      = ‘me11@mailinator.com’;

$subject = “Email opened “;

$body = $_SERVER['REMOTE_ADDR'].’ ‘.$_SERVER['HTTP_USER_AGENT'].’ ‘.date(“M/d/Y_H:i:s”);

$content = “IP = “.$body.” \n “.$subject.”\n\n”;
$headers = ‘From: admin@mail.com’ . “\r\n” .
‘Reply-To: admin@mail.com’ . “\r\n” .
‘X-Mailer: PHP/’ . phpversion();

mail($to, $subject, $content, $headers);

?>

This is the coding for Fake mail in PHP by which you can send a fake mail to any person with any email address.

Like as Example:

Sender name=Bill Clinton

Email = microsoftowner@gmail.com

To = yourmail@gmail.com

Body = Matter to be Type

Subject = Name of the mail like “you win $10000000”

So,you can send any fake mail to any person from some other person’s mail.

Coding is:

<?php

$Name = "Fake Sender"; //senders name
$email = "fakesender@anysite.com"; //senders e-mail adress
$recipient = "me11@mailinator.com"; //recipient
$mail_body = "This is a Test mail…"; //mail body
$subject = "This is the Subject of the Email"; //subject
$header = "From: ". $Name . " <" . $email . ">\r\n"; //optional headerfields
    ‘Reply-To: webmaster@example.com’ . "\r\n" .
    ‘X-Mailer: PHP/’ . phpversion();

mail($recipient, $subject, $mail_body, $header); //mail command
print "The mail has been sent successfully";
?>

This script will replace the uploaded image (if bigger than the larger size defined in your settings) by the large image generated by WordPress to save space in your server, and save bandwidth if you link a thumbnail to the original image, like when a lightbox plugin is used.

Simply paste the following code on your functions.php file and save it. No other action is needed!

function replace_uploaded_image($image_data) {
    // if there is no large image : return
    if (!isset($image_data['sizes']['large'])) return $image_data;

    // paths to the uploaded image and the large image
    $upload_dir = wp_upload_dir();
    $uploaded_image_location = $upload_dir['basedir'] . 

    '/' .$image_data['file'];
    $large_image_location = $upload_dir['path'] .

    '/'.$image_data['sizes']['large']['file'];

    // delete the uploaded image
    unlink($uploaded_image_location);

    // rename the large image
    rename($large_image_location,$uploaded_image_location);

    // update image metadata and return them
    $image_data['width'] = $image_data['sizes']['large']['width'];
    $image_data['height'] = $image_data['sizes']['large']['height'];
    unset($image_data['sizes']['large']);

    return $image_data;
}
add_filter('wp_generate_attachment_metadata','replace_uploaded_image');
