Re: Getting PHP 8 to use mibs in the mibs folder

Hi Drew,

Heaven knows it's been so long that you've probably found an answer ... I'm
not on RHEL (PHP 8.4.5 on macos 12.5) but, in case the behavior is the
same, appending to the MIBS env var helped me (at least spared me from a
code change specifying MIBs). From my digging around, it looks like my PHP
was finding all the MIBS in my MIBDIR but using a default set of files.
Specifying MIBS=+ hinted to it to append some extra mibs to the default
mibs list for parsing ...

MIBS=+RFC1213-MIB:RFC1155-SMI php test.php


If the behavior is the same for your setup, then ... I suppose it's still a
bit clunky because you'd have to append all the (hundreds of) MIBS you care
about. On my setup, it looks like there are conf files that might house
this variable. Maybe something like that would keep from cluttering up your
command-line ...

Hope you find the solution you're looking for,
Patty
