How can developers troubleshoot and debug PHP scripts that intermittently fail, such as in the case of inconsistent file uploads?

Intermittent failures in PHP scripts, such as inconsistent file uploads, can be challenging to troubleshoot. One approach is to check for errors in the file upload process, such as file size limits or file type restrictions. Additionally, logging errors and debugging information can help identify the root cause of the intermittent failures. 

if ($_FILES['file']['error'] !== UPLOAD_ERR_OK) {
    echo 'File upload failed with error code: ' . $_FILES['file']['error'];
} else {
    move_uploaded_file($_FILES['file']['tmp_name'], 'uploads/' . $_FILES['file']['name']);
    echo 'File uploaded successfully!';
}
