What are best practices for generating user-friendly URLs in PHP without exposing IDs?

When generating user-friendly URLs in PHP, it is important to avoid exposing internal IDs as they can pose security risks and make the URLs less user-friendly. One common practice is to use slugs or friendly names instead of IDs in the URL. This can be achieved by storing a unique slug for each resource in the database and using it to generate the URL. 

// Example code snippet for generating user-friendly URLs without exposing IDs
function generateSlug($str) {
    $slug = strtolower(trim(preg_replace('/[^A-Za-z0-9-]+/', '-', $str)));
    return $slug;
}

// Assuming $title is the title of the resource
$title = "Example Title";
$slug = generateSlug($title);

// Construct the user-friendly URL
$url = "https://example.com/" . $slug;
echo $url;
