Are there any specific PHP functions or methods recommended for handling directories and files?

When working with directories and files in PHP, it is recommended to use built-in functions and methods to ensure proper handling and avoid errors. Some commonly used functions for handling directories include `opendir()`, `readdir()`, `closedir()`, `mkdir()`, and `rmdir()`. For file handling, functions like `fopen()`, `fwrite()`, `fread()`, `fclose()`, `file_get_contents()`, and `file_put_contents()` are commonly used. 

// Example of creating a directory and writing to a file
$dir = 'new_directory';
$file = $dir . '/new_file.txt';

// Create a new directory
if (!is_dir($dir)) {
    mkdir($dir);
}

// Write to a new file
$fileHandle = fopen($file, 'w');
fwrite($fileHandle, 'Hello, World!');
fclose($fileHandle);

echo 'File created successfully.';
