Are there specific PHP functions or methods that are recommended for quickly checking domain availability in a database?

When checking domain availability in a database, it is recommended to use a PHP function that queries the database for the domain name and returns a boolean value indicating its availability. One common approach is to use a SQL SELECT query to check if the domain exists in the database. 

<?php

function isDomainAvailable($domain) {
    // Connect to your database
    $conn = new mysqli('localhost', 'username', 'password', 'database');

    // Check if the domain exists in the database
    $query = "SELECT domain FROM domains WHERE domain = '$domain'";
    $result = $conn->query($query);

    // Return true if domain is available, false otherwise
    if ($result->num_rows == 0) {
        return true;
    } else {
        return false;
    }

    // Close the database connection
    $conn->close();
}

// Example usage
$domain = "example.com";
if (isDomainAvailable($domain)) {
    echo "Domain is available!";
} else {
    echo "Domain is not available.";
}

?>
