What are some best practices for optimizing a website with millions of entries for Google indexing, specifically in relation to PHP?

When optimizing a website with millions of entries for Google indexing in PHP, it is important to ensure that each page has a unique and descriptive meta title and meta description. This will help Google accurately index and display your pages in search results. Additionally, creating a sitemap.xml file that lists all of your website's pages can help Google easily crawl and index your content. 

<?php
// Set unique meta title and meta description for each page
$meta_title = "Page Title";
$meta_description = "Page Description";

// Output meta tags in HTML
echo "<title>{$meta_title}</title>";
echo "<meta name='description' content='{$meta_description}'>";

// Create sitemap.xml file
$filename = "sitemap.xml";
$entries = array("entry1", "entry2", "entry3"); // Replace with actual entries

$xml = new SimpleXMLElement('<urlset/>');

foreach($entries as $entry) {
    $url = $xml->addChild('url');
    $url->addChild('loc', "https://www.example.com/{$entry}");
}

$xml->asXML($filename);
?>
