How can PHP developers troubleshoot issues with file uploads not working?

To troubleshoot issues with file uploads not working in PHP, developers can check the following: 1. Ensure that the form tag has the attribute enctype="multipart/form-data". 2. Verify that the upload_max_filesize and post_max_size settings in php.ini are large enough to accommodate the file being uploaded. 3. Check the permissions of the upload directory to ensure that PHP has write permissions. 

<form action="upload.php" method="post" enctype="multipart/form-data">
    <input type="file" name="file">
    <input type="submit" value="Upload">
</form>
