How can DNS cache settings affect the retrieval of IP addresses in PHP?

DNS cache settings can affect the retrieval of IP addresses in PHP by causing outdated or incorrect IP addresses to be returned if the cache is not properly cleared or updated. To solve this issue, you can use the `dns_get_record()` function in PHP to retrieve the latest IP address information directly from the DNS server, bypassing any cached data. 

// Retrieve IP address information directly from DNS server
$dns_records = dns_get_record("example.com", DNS_A);
foreach ($dns_records as $record) {
    if ($record['type'] == 'A') {
        $ip_address = $record['ip'];
        break;
    }
}
echo "IP Address: " . $ip_address;
