Please try using this CVS snapshot:

  http://snaps.php.net/php4-STABLE-latest.tar.gz
 
For Windows:
 
  http://snaps.php.net/win32/php4-win32-STABLE-latest.zip

I've got exectly the same problem and I tryed to use the CVS snapshot you proposed, but the result is the same as it was before: I execute my programm with Oracle interaction for 2-3 times and then I get the error "Document contains no data" every time I try to connect to Oracle in my programm. If I execute any other php without Oracle interaction - it works. 
Apache's error log contains the line:  
[Wed Jun 04 09:16:40 2003] [notice] child pid 3340 exit signal Segmentation fault (11)

Thanks,

Elena

As our documentation describes, you need to set the environment vars BEFORE you start apache. Setting it in a script won't work:
putenv("ORACLE_SID=coastal");
putenv("ORACLE_HOME=/oracle");
putenv("TNS_ADMIN=/oracle/network/admin/tnsnames.ora");

I tryed to backtrace the error and that's what I've got:

Hopefully it can help somehow...

The variables $ORACLE_HOME and others were set before apache started - it didn't help...

We encountered the same problem, but it seem to be a oracle9 (9ir2) issue. After switching back to oracle 8 everything works as expected.

With PHP 4.2.3 and oracle 9 it works, but with 4.3.2 not. 
Today I tried a latest snap-shot ( php4-STABLE-200306131730 ) and it seems to work again as expected.

No segfault or stange SQL-errors.

Friends, I am an Oracle DBA and I supporting a team developing with PHP and we are facing this very issue. Questions:

1) When you say it works with Oracle8 -- is it olny the client or the Oracle server ?

2) We would like to know if this workaround is only for Oracle8 (8.0.x) or does it also work for Oracle8i (8.1.x) ? 

Thanks, Andre

I am a developer setting up oracle 9ir2 client under redhat with apache 1.3.27-2 and this is the exact same issue.. identical, however the cvs snapshots did not help me, i continue to have the same issue with it, would it be recommendable to downgrade? or has there been a specific fix released for this?
