Open-source Languages & Tools for z/OS

I would like to use PHP 7 scripts to access DB2 on z/OS.
Is it possible and if so, are there some config guidelines to make it work?
I used to have access to DB2 when using PHP5 on the old Domini Go Webserver,
but now using the Apache-based http-server I don’t seem to get things working.

Hi,

Since the current version of IBM HTTP Server admits only EBCDIC-encoded
headers, build 008 makes CGI output encoding controlled by environment
variables:
CGI_HEADER_ENCODING - for headers
CGI_BODY_ENCODING - for all data excepting headers
Possible values for these environment variables are:
EBCDIC - force EBCDIC-encoded output
ASCII - force ASCII-encoded output
NONE - no data conversion

Recommended settings for IBM HTTP Server are in Apache configuration file:

CharsetSourceEnc ISO8859-1
CharsetDefault ISO8859-1

Also recommended to set following environment variables:

export CGI_HEADER_ENCODING=EBCDIC
export CGI_BODY_ENCODING=NONE
export _BPXK_AUTOCVT=ON

These environment variables can be set in Apache configuration file, e.g.

SetEnv CGI_HEADER_ENCODING EBCDIC
SetEnv CGI_BODY_ENCODING NONE
SetEnv _BPXK_AUTOCVT ON

or in PHP CGI wrapper script, e.g.

#!/bin/sh
export CGI_HEADER_ENCODING=EBCDIC
export CGI_BODY_ENCODING=NONE
export _BPXK_AUTOCVT=ON
/rsusr/rocket/bin/php-cgi “$@”

To run php with IBM DB2 ODBC driver provide necessary dynamic link libraries
using STEPLIB environment variable, e.g.

export STEPLIB=DSN1110.SDSNEXIT:DSN1110.SDSNLOAD:DSN1110.SDSNLOD2

The path to ODBC connection initialization (INI) file can be set with DSNAOINI
environment variable

export DSNAOINI=/path/to/ini_file

This file should be EBCDIC-encoded, tagged as binary and contain

CURRENTAPPENSCH=ASCII

Thanks,
Sergey
