[Refdb-users] refdbc and php4

[Howard S. <ho...@uk...>]

Hello

RefDB works perfectly on my system, and my LAMP system works
fine, but I need to use refdbc from PHP. I can't use the
cgi version.  I can't get this to work.  If I try the command

/usr/local/bin/refdbc -C getref :AU:=richter

from the command line, it works correctly and gives me 13
references.  If I try it in a shell script, it also works.
But if I try calling this command with the PHP functions 'system'
'exec' 'passthru', etc, or with a pipe, it returns an
error.  The log file for the refdbd daemon has this:

6:pid=3856:Tue Jan 28 11:49:17 2003:adding client on fd 6
6:pid=3856:Tue Jan 28 11:49:17 2003:server waiting n_max_fd=6
6:pid=12484:Tue Jan 28 11:49:17 2003:serving client on fd 6 with
protocol version 0
4:pid=12484:Tue Jan 28 11:49:17 2003:unknown command
4:pid=12484:Tue Jan 28 11:49:17 2003:no positive ack from client
6:pid=12484:Tue Jan 28 11:49:17 2003:child finished client on fd 6
6:pid=3856:Tue Jan 28 11:49:17 2003:parent removing client on fd 6
6:pid=3856:Tue Jan 28 11:49:17 2003:server waiting n_max_fd=5
6:pid=3856:Tue Jan 28 11:49:17 2003:child exited with code 1

If I set the log level to 'debug' (-l7) in refdbc, I get this
in the log file when calling from PHP:

7:pid=15100:Tue Jan 28 15:20:35 2003:getref :AU:=richter

If I call the program directly (or from a shell) this
is

7:pid=14990:Tue Jan 28 15:14:20 2003:getref ":AU:=richter" -u zmpg -w 
121069035118125116045057 -d ZMPGlit -R 
/home/local/ZMPG/zmpg/Documents/PDFs -G /usr/local/share/refdb/css/refdb.css

In other words, when I call refdbc from PHP, it ignores both
the configuration file and most of the command line parameters.

What are the special tricks for getting refdbc to work from PHP?

Thanks,
