<form action="upload.php" method="post" ENCTYPE="multipart/form-data">
File: <input type="file" name="file" size="30"> <input type="submit" value="Upload!">
</form>

upload.php :

 <?php
// ==============
// Configuration
// ==============
$uploaddir = "uploads"; // Where you want the files to upload to - Important: Make sure this folders permissions is 0777!
$allowed_ext = "jpg, gif, png, pdf"; // These are the allowed extensions of the files that are uploaded
$max_size = "50000"; // 50000 is the same as 50kb
$max_height = "100"; // This is in pixels - Leave this field empty if you don't want to upload images
$max_width = "100"; // This is in pixels - Leave this field empty if you don't want to upload images 

// Check Entension
$extension = pathinfo($_FILES['file']['name']);

// Check File Size

// Check Height & Width
