What potential pitfalls can arise when server administrators disable functions like copy() and move_uploaded_file() for PHP uploads?

Disabling functions like copy() and move_uploaded_file() for PHP uploads can prevent the server from properly handling file uploads, leading to errors or incomplete uploads. To solve this issue, server administrators can instead use the PHP function move_uploaded_file() to securely move uploaded files to the desired location. 

if(isset($_FILES['file'])){
    $file_name = $_FILES['file']['name'];
    $file_tmp = $_FILES['file']['tmp_name'];
    
    $upload_dir = 'uploads/';
    
    if(move_uploaded_file($file_tmp, $upload_dir . $file_name)){
        echo 'File uploaded successfully.';
    } else {
        echo 'Error uploading file.';
    }
}
