What are some best practices for checking directories for files and constructing variable names in PHP?

When checking directories for files in PHP, it is important to use the appropriate functions like `scandir()` or `glob()` to retrieve the list of files. To construct variable names dynamically based on the files found, you can use a loop to iterate through the files and assign them to variables. It is also recommended to sanitize the file names before using them as variable names to prevent any potential security risks. 

// Check directory for files
$files = scandir('/path/to/directory');

// Construct variable names based on files found
foreach ($files as $file) {
    if ($file != '.' && $file != '..') {
        $sanitizedFileName = preg_replace("/[^a-zA-Z0-9_\-]/", "", $file); // Sanitize file name
        ${$sanitizedFileName} = file_get_contents('/path/to/directory/' . $file); // Assign file contents to variable
    }
}
