Q:

PHP cant find SNMP modules under Windows 7

I've enabled the SNMP module was trying to the functions in the module.  I have set the MIBDIRS environment variable to where I have my mibs but I'm still getting these "Cannot find module" warnings:
Cannot find module (IP-MIB): At line 0 in (none)

My php.ini settings are:
mibdir=C:\\Users\username\Downloads\Applications\Dev\PHP\5.4\net-snmp-mibs\net-snmp-5.7.2.1\mibs
mibs=all
extension=php_snmp.dll

I'm on Windows.
And it still gives those errors...
Any insights please?

A:

The PHP docs is misleading for Windows;
In order to get rid of the errors and have SNMP module working properly, you MUST add an environment variable in the System, called MIBDIRS and pointing to the location of your mib files.
On Windows 7 for example, that would be System Properties > Environment Variables > User variables section, click New and add MIBDIRS, with value of C:\usr\mibs (or wherever you put the mibs folder).
The files should be extracted using a Net-SNMP package, tested with version net-snmp-5.7.2.1 on PHP 5.4.7 using CLI mode.
