What is the significance of "." and ".." in the context of directory navigation and PHP code?

In directory navigation, "." represents the current directory, while ".." represents the parent directory. In PHP code, these symbols are commonly used to navigate through directories when working with files and folders. To properly navigate directories using PHP, you can use the `scandir()` function to get the list of files and directories in a specific path, and then filter out "." and ".." to avoid processing them. 

// Get list of files and directories in a specific path
$files = scandir('/path/to/directory');

// Filter out "." and ".."
$files = array_diff($files, array('.', '..'));

// Process remaining files and directories
foreach ($files as $file) {
    // Process each file or directory
}
