Are there any best practices for handling directory checking in PHP?

When checking directories in PHP, it is important to handle potential errors and exceptions that may occur. One best practice is to use the `is_dir()` function to check if a directory exists before attempting to perform any operations on it. Additionally, it is recommended to use the `try-catch` block to catch any exceptions that may be thrown during directory checking. 

$directory = "/path/to/directory";

if (is_dir($directory)) {
    echo "Directory exists!";
} else {
    echo "Directory does not exist!";
}

try {
    $files = scandir($directory);
    // Perform operations on directory files
} catch (Exception $e) {
    echo "Error: " . $e->getMessage();
}
