What are some best practices for troubleshooting PHP scripts that rely on external files, such as checking for hidden files or directories?

When troubleshooting PHP scripts that rely on external files, it's important to check for hidden files or directories that may be causing issues. One way to do this is to ensure that your script is able to access all necessary files and directories by checking for hidden files or directories that may be preventing proper execution. 

// Check for hidden files or directories
$files = scandir('/path/to/directory');
foreach ($files as $file) {
    if ($file[0] === '.') {
        // Handle hidden file or directory
        echo "Hidden file or directory found: $file";
    }
}
