Are there any specific PHP functions or methods that can simplify the process of writing to multiple directories?

When writing to multiple directories in PHP, you can simplify the process by using the `mkdir` function to create the directories if they do not already exist, and then using the `file_put_contents` function to write to the files within those directories.

$directories = ['dir1', 'dir2', 'dir3']; // Array of directory names
$fileContent = 'Hello, world!'; // Content to write to the files

foreach ($directories as $dir) {
    if (!is_dir($dir)) {
        mkdir($dir, 0777, true); // Create directory if it doesn't exist
    }
    
    file_put_contents($dir . '/example.txt', $fileContent); // Write content to file in directory
}
