PHP 5.4.33 Released


PHP 5.3.0, 5.3.1 and 5.3.2 do not have SNMP support. SNMP support has been restored in PHP 5.3.3.

The Windows distribution of Net-SNMP contains support files for SNMP in the mibs directory. This directory should added to Windows' environment variables, as MIBDIRS, with the value being the full path to the mibs directory: e.g. c:\usr\mibs.

Important notes for PHP prior to 5.4.0: In order to use the UCD SNMP package, you need to define NO_ZEROLENGTH_COMMUNITY to 1 before compiling it. After configuring UCD SNMP, edit config.h or acconfig.h and search for NO_ZEROLENGTH_COMMUNITY. Uncomment the #define line. It should look like this afterwards:

Now compile PHP --with-snmp[=DIR] .

If you see strange segmentation faults in combination with SNMP commands, you did not follow the above instructions. If you do not want to recompile UCD SNMP, you can compile PHP with the --enable-ucd-snmp-hack switch which will work around the misfeature.

For win32 (tested on win XP and 2k3 server 32bit):
Tested with versions 5.3.3 VC9, and 5.3.6 VC9.
The php_snmp.dll, requires that you set the environment variable MIBDIRS pointed to your MIBs folder.

If net-snmp was not installed in default c:\usr folder (which may be the case for most peoples used to Windows instead of Linux), then, you should also create SNMP_PERSISTENT_DIR system environment variable with "persistent" folder location (located in snmp folder).
Otherwise, php will will create its own persistant folder in c:/usr/snmp/persistent folder, which is probably not what you want !

If PHP complains that some mibs are missing and they are not included in your windows php package, they can be obtained from the source package of net-snmp itself.

In order to build and install php in Ubuntu 12.10, beyond the normal "build-essential" package, I had to install the following packages: apache2-prefork-dev  libxml2-dev libsnmp libsnmp-dev libtool

Command line should be like this:

sudo apt-get install apache2-prefork-dev libxml2-dev libsnmp libsnmp-dev libtool
