To
programming a SNMP application with PHP is a simple job, it’s not a difficult
thing, but you must have at least these things:.

1. Have a SNMP installed on your
        Windows.
2. Have a snmputil.exe, make
        sure you have the original EXE
        that made by Microsoft Corporation, or you can download it here
3. Have knowledge about SNMP and
        how it works.
4. PHP Server is installed on
        your PC
5. Have knowledge in programming
        with PHP.

 
First,
you must have SNMP installed on your Windows, go to Control Panel -> Add/Remove Programs -> Add/Remove Windows
Components -> Management and Monitoring tools .. Checklist on Simple Network Management Protocol. And
OK… I highly recommend to restart the PC after this step.

 
Second,
put your snmputil.exe in C:\ directory, and run it from CMD..
Type:
C> snmputil get 127.0.0.1 public
.1.3.6.1.2.1.1.1.0, if the
result looks like below,

SNMP
is runs perfectly

CONNECTING PHP AND SNMP

Third,
Edit your php.ini file so that php
load SNMP module, this module used by PHP to connect with SNMP that installed
on your PC.

How
to edit ??? go to your server directory and find file php.ini, for example if
you use XAMPP server, the default directory would be  C:\Program
Files\xampp\apache\bin, please check your server manual, or run phpinfo(); to get  info where
your php.ini is located.

Back
to php.ini editing, open your php.ini with notepad and find the line ;extension=php_snmp.dll
and omit the semicolon (;) so
the line will be extension=php_snmp.dll,
Save the file, and restart your PHP server, don`t know how to do it ?? restart
is only turn-it-off-and-turn-it-on-again
action.. still not understood ? pliz googling it and find the answer for
yourself L

Now,
the final is… Write down, save as PHP file, and run the script below from
your server.

<?php

     $result=snmpget”127.0.0.1”,
“public”,” .1.3.6.1.2.1.1.1.0”);
     echo
$result;
?>

 
if
the result has no error message in it, congratz,, now you can do programming
with SNMP through PHP, you can search on internet for more info about SNMP
syntax and OID in PHP.
