What potential benefits or drawbacks could arise from including all files from a directory in PHP?

Including all files from a directory in PHP can be beneficial for automating tasks, such as loading classes or configuration files dynamically. However, it can also pose security risks if the directory includes sensitive files or if proper validation is not performed on the files being included.

// To include all files from a directory in PHP while ensuring security, you can use the following code snippet:

$directory = 'path/to/directory';
$files = glob($directory . '/*.php');

foreach ($files as $file) {
    include_once $file;
}
