Are there any best practices for handling SNMP data retrieval in PHP scripts?

When handling SNMP data retrieval in PHP scripts, it is important to properly handle errors and timeouts that may occur during the retrieval process. One best practice is to use try-catch blocks to catch any exceptions that may be thrown by the SNMP functions. Additionally, setting appropriate timeouts for SNMP requests can help prevent the script from hanging indefinitely. 

<?php

// Set the SNMP timeout value in seconds
$timeout = 5;

// Create an SNMP session
$session = new SNMP(SNMP::VERSION_2C, 'localhost', 'public', $timeout);

try {
    // Retrieve the value of the specified OID
    $value = $session->get('SNMPv2-MIB::sysDescr.0');
    echo "SNMP data retrieved: " . $value . "\n";
} catch (Exception $e) {
    echo "Error retrieving SNMP data: " . $e->getMessage() . "\n";
}

// Close the SNMP session
$session->close();

?>
