What are the best practices for setting file permissions when using scandir() in PHP?

When using scandir() in PHP to read the contents of a directory, it is important to set appropriate file permissions to ensure the security of your files. A common best practice is to set the directory permissions to 755 (read, write, and execute for owner, read and execute for group and others) and file permissions to 644 (read and write for owner, read for group and others). 

// Set directory permissions to 755
chmod('/path/to/directory', 0755);

// Set file permissions to 644
$files = scandir('/path/to/directory');
foreach($files as $file) {
    if(is_file('/path/to/directory/' . $file)) {
        chmod('/path/to/directory/' . $file, 0644);
    }
}
