Brian Havard already released the OS/2 port of the shortly released PHP Version 4.0.2. He also compiled a second PHP module with DB2 support.
This is the description taken from Brian's website:
A PHP4 loadable module ( 723k) of the v4.0.2 release. This build has not been heavily tested. For more information on PHP see the PHP home
page Optional libraries included are
GDBM v1.7.3
MySQL client v3.23.10
PostgreSQL client v7.0.2
ZLib v1.1.3
GD v1.2
FreeType v1.2
t1lib v0.9.2
PDFLib v3.0
A PHP4 loadable module with IBM DB2 support ( 738k) of the v4.0.2 release. Like the above but additionally supports access to IBM DB2
databases. This is not included in the standard build above because this module will not load if a DB2 client is not installed.
