    We have to Put enctype = "multipart/form-data" inside the form

      <html>
  <body>
  <form action = "" method = "POST" enctype = "multipart/form-data">
     <input type = "file" name = "image" />
     <input type = "submit"/>
      
     <ul>
        <li>Sent file:  echo $_FILES['image']['name'];  
        <li>File size:  echo $_FILES['image']['size'];  
        <li>File type:  echo $_FILES['image']['type'] 
        <li><img src=" echo 'images/'.$file_name; "> 
     </ul>
      
  </form>
      </body> </html>

    We Have

      //file_upload.php

  if(isset($_FILES['image'])){$errors= array();

  $file_name = $_FILES['image']['name'];

  $file_size = $_FILES['image']['size'];

  $file_tmp = $_FILES['image']['tmp_name'];

  $file_type = $_FILES['image']['type'];

  $file_ext=strtolower(end(explode('.',$_FILES['image']['name'])));
  
  $extensions= array("jpeg","jpg","png");
  
  if(in_array($file_ext,$extensions)=== false){
     $errors[]="extension not allowed, please choose a JPEG or PNG file.";
  }
  
  if($file_size > 2097152) {
     $errors[]='File size must be excately 2 MB';
  }
  
  if(empty($errors)==true) {
     move_uploaded_file($file_tmp,"images/".$file_name);
     echo "Success";
  }else{
     print_r($errors);
  }    } ?>

    Just do this

    echo '<img src="upload/'.$file_name.' "/>

    We have to take the $file_name variable because.. "" (double quotes) can only return text in the variable - it cannot return binary number to show image!
