How can PHP code be structured to efficiently handle multiple domain name search criteria?

To efficiently handle multiple domain name search criteria in PHP, you can use an array to store the domain names and then loop through the array to perform the search operation. This approach allows for easy scalability and maintenance of the code.

<?php
// Array of domain names to search
$domainNames = ['example1.com', 'example2.com', 'example3.com'];

// Loop through the array to search for each domain name
foreach ($domainNames as $domain) {
    // Perform search operation for $domain
    // Your search logic here
}
?>
