IBM iseries i5 php system command

I am running PHP on an IBM iSeries i5 machine.  From within a PHP script I am trying to issue the "system()" command.  As far as I can tell nothing is happening.  I have tried "system()", "exec()", "shell_exec()" but nothing works.  Can someone point me in the right direction?  Thank you!
system("SNDMSG MSG('this is a test 2') TOUSR(RCRIST)");

I'm not a PHP expert, but maybe this will get you going in the right direction:

PHP runs in the PASE environement.  I assume this means that if you use system(), exec(), shell_exec(), etc, you probaby need to use PASE commands and not native (OS/400) commands.  The PASE "system" command is used to run OS/400 commands from a PASE session.

CALL QP2TERM   /* Starts a PASE terminal session */
system 'SNDMSG MSG('this is a test 2') TOUSR(RCRIST)'

Will allow you run the SNDMSG command from PASE.  The full path to "system" is /QOpenSys/usr/bin/system, so if you need to specify a path:

/QOpenSys/usr/bin/system 'SNDMSG MSG('this is a test 2') TOUSR(RCRIST)'

should do it.

You'll have to figure out how to get it quoted properly, I suspect.

This redbook has some info and examples on getting started with PHP on AS/400:

You are a Guru!  No...really.   :)

Thanks, Gary, for your help on this and other stuff in the past!  Your idea worked great!  Below is what I ended up doing:

  $cmd = "/QOpenSys/usr/bin/system \"SNDMSG  MSG('hello 5') TOUSR(RCRIST)\"";
  system($cmd);
