How can PHP be used to automate the retrieval of WAN-IP address information from a router?

To automate the retrieval of WAN-IP address information from a router using PHP, you can use SNMP (Simple Network Management Protocol) to query the router for this information. By sending an SNMP request to the router's IP address and using the appropriate OID (Object Identifier) for WAN-IP address, you can retrieve the information programmatically. 

<?php
$routerIp = '192.168.1.1'; // Replace with your router's IP address
$snmpCommunity = 'public'; // Replace with your SNMP community string

$wanIpOid = '1.3.6.1.2.1.4.20.1.1'; // OID for WAN-IP address

// Use SNMP to retrieve WAN-IP address from the router
$wanIp = snmpget($routerIp, $snmpCommunity, $wanIpOid);

echo "WAN-IP Address: $wanIp";
?>
