$target_file1 = basename($_FILES["file"]["name"]);
$target_file = $target_dir . basename($_FILES["file"]["name"]);

$uploadOk = 1;

$imageFileType = strtolower(pathinfo($target_file,PATHINFO_EXTENSION));
// Check if image file is a actual image or fake image
  $check = getimagesize($_FILES["file"]["tmp_name"]);
  if($check !== false) {
    echo "File is an image - " . $check["mime"] . ".";?><br><?php
    $file = $target_file1;
    $filesize = filesize($file); // bytes
    $filesize = round($filesize / 1024, 2); // kilobytes with two digits
    echo "The size of your file is $filesize KB.";?><br><?php

    echo "Content last changed: ".date("F d Y H:i:s.", filemtime($file));?></p>

    $imageFileType = strtolower(pathinfo($target_file,PATHINFO_EXTENSION));

    // Check if image file is a actual image or fake image
