Thanks Daniel for your suggestions.
What I have found are:
1) I'm assuming the key is good. A value of 1947143245 is returned.
2) I have set the permission of the shared memory ("program.SCShared") to
777 octal (full read/write/execute access). The group and owner of the file
is my login ('eclips

Are you certain that the problem lies within the shmop reading?
Check to see if the file is actually being accessed properly, the key

Hi,
Thank you for your answer. I was hoping there were a solution. :-/ It would
have been nice as PHP has a large install base and is a quite common element
in cheap web hosting solutions. Has anyone else got any more comments or
suggestions?

I tried the php function chmod($sem, 0644) which works fine even if it
converts the octal number too, cf. xdebug trace file:
0.0037 50280 -> chmod('/tmp/1521387531.sem', 420)
...myScripts/test.php:11

Yes, thank you. I checked this thread before writing here. But following the
hints there does not help either.

Thank you for your reply.
shmop_open($sem_key, "w", 420, 1) creates the same error message:

Thanks for your reply, but I afraid you did not get my point. I am
talking about shared memory that is used for Interprocess
communication. We can access the shared memory created by one C
program in other C program and same is the case with php. I am trying
to communicate with a C program from php

I would hope not, as this would cause major security problems and system

of course not there are two different procs.

One of the things you have to realize is that Apache-1.3.x is is

have many processes handling requests. You never know which process will

Hit Thomas,
you need to recompile PHP with the options you want (as a shared apache
module) and then replace libphp4.so on /usr/lib/apache/ with your own
version.
A good thing is to keep SuSE's version as a backup:-)
Don't forget to restart apache afterwards. (/etc/rc.d/apache stop;
