PHP’s upload checks are the last line of defense against malicious content There are a few more checks that we need to accomplish to solidify our form submission. You can never be too careful especially when allowing others to upload files to your server. I recommend using a tried and tested PHP package, but we’re learning how stuff works here so we’ll do a few more tests ourselves. Recap We have a basic HTML form and a simple process script. <form action=”./upload.php” method=”post” enctype=”multipart/form-data”> <div> Select Image to upload: </div> <div> <input type=”file” name=”file_name” id=”file_name”> </div> <div> <input type=”submit”
