Description:
------------
SNMP functions cause "PHP has encountered an Access Violation" when
wrong IP or Community String.
IIS 6 + PHP5.2.2dev isapi module.
PHP_snmp.dll (ver 5.2.2.2)
All next php versions has the same problem.
After this error, IIS does not can operate with snmp module and needs
to be restarted.

No errors in php_error.log

<?php
echo "Start...";

$communitystring=''; // Your device must have this string no empty!
$ip='10.200.202.97'; // Sometimes this error occured, when there is no
Device in a network with this IP.
for ($i=1;$i<14;$i++)
{
$port=100+$i;
$oid='.1.3.6.1.2.1.26.2.1.1.5.${port}.1';
@snmpget($ip,$communitystring,$oid);
$oid='.1.3.6.1.2.1.26.2.1.1.5.${port}.1';
