What are some alternative resources or approaches for troubleshooting file upload issues in PHP, aside from the official documentation?

When troubleshooting file upload issues in PHP, one alternative resource is online forums or communities where developers can ask for help and receive suggestions from experienced individuals. Another approach is to use debugging tools like Xdebug to step through the code and identify any errors or issues that may be causing the problem. Additionally, utilizing logging mechanisms such as error_log or PHP's built-in error handling functions can help track down the source of the upload problem. 

// Example code snippet using error_log to log file upload issues
if ($_FILES['file']['error'] > 0) {
    error_log("File upload error: " . $_FILES['file']['error']);
    // Handle the error accordingly
} else {
    // Process the uploaded file
}
