Php snmp function Error

Tip:
Fatal error: Call to undefined function snmpwalkoid () in E: \ proj \ PHP \ SNMP. php on line 2

Code:
<? PHP
$ A = snmpwalk ("127.0.0.1", "public ","");
Foreach ($ A as $ Val ){
Echo "$ Val <br> ";
}
?>

Solution:
1. install PHP and Its modules
A) decompress the package;
B) modify PHP. ini-Dist to PhP. ini;
2. Configuration File
A) modify the php. ini configuration file.
I. Modify extension_dir = c: \ PHP \ extensions
Ii. Delete the quotation marks (;) before the extended modules you need, for example:
Originally:
; Extension = php_snmp.dll
To:
Extension = php_snmp.dll
B) configure system environment variables (not required in this step)
I. Add c: \ PHP (PHP installation directory) to the environment variable path)
Ii. Add a variable, right-click my computer-properties-advanced-Environment Variable-system variable-New mibdirs = C: \ PHP \ mibs, and create phprc = c: \ PHP
Iii. Modify the registry (if not, create a new string value ):
HKEY_LOCAL_MACHINE → software → PHP → inifilepath
Value: C: \ PHP (PHP installation directory)

After all the work is done, restart.
Create a PHP file:
Code:
<? PHP
$ A = snmpwalk ("127.0.0.1", "public ","");
Foreach ($ A as $ Val ){
Echo "$ Val <br> ";
}
?>
You can see the effect.

The SNMP configuration for Windows 2003 is required:
SNMP in Windows 2003 does not allow direct access by default. You need to configure some parameters.

Download net-snmpinstallation from http://www.net-snmp.org/download.html.

After installing SNMP, you can view the security options in the SNMP service of the Windows service.

Select the send Authentication Trap, add the public group, and read-only permission.

Select Accept SNMP Packets from these hosts and add the IP address of the SNMP browser.

For Linux, configure the snmpd. conf file:
# Vi/etc/snmp/snmpd. conf
Modify the snmpd. conf file
