What are some best practices for handling file uploads in PHP to avoid errors like "Unable to access" messages?

When handling file uploads in PHP, it's important to ensure that the correct file permissions are set on the upload directory to prevent "Unable to access" errors. This can be done by setting the correct permissions on the upload directory using chmod function in PHP. 

// Set the correct permissions on the upload directory
$uploadDir = 'uploads/';
if (!is_dir($uploadDir)) {
    mkdir($uploadDir, 0777, true);
} else {
    chmod($uploadDir, 0777);
}
