What are common issues when setting up a file upload feature on a PHP website?

One common issue when setting up a file upload feature on a PHP website is ensuring that the server has proper permissions to write files to the designated upload directory. This can be resolved by adjusting the permissions of the upload directory to allow the web server to write to it. 

// Set the upload directory path
$uploadDir = 'uploads/';

// Ensure the upload directory exists and has proper permissions
if (!file_exists($uploadDir)) {
    mkdir($uploadDir, 0777, true);
}
