What is the difference between accessing image files through $_POST and $_FILES in PHP?

When uploading image files in PHP, it is important to note that the file data should be accessed through the $_FILES superglobal, not $_POST. $_POST is used to retrieve form data that is sent via POST method, while $_FILES is specifically designed to handle file uploads. By using $_FILES, you can access information such as the file name, file size, file type, and temporary location of the uploaded file. 

// Accessing image file uploaded through a form using $_FILES
if(isset($_FILES['image'])){
    $file_name = $_FILES['image']['name'];
    $file_size = $_FILES['image']['size'];
    $file_type = $_FILES['image']['type'];
    $file_tmp_location = $_FILES['image']['tmp_name'];
    
    // Process the uploaded file here
}
