Re: Getting PHP to write back to a data queue

If we do not tie our code to a particular hardware platform - then why use that platform? Why use a sophisticated server like an iSeries when a less expensive Intel based system can do the same job? Just stick a linux server in and switch off the system i.

If everything on the system i can run on Intel, then it is inevitable that the system i will eventually be replaced by Intel based solutions. The system i will Die!!!

Businesses buy "proprietry" hardware because they believe it is cost effective. Because this "proprietry" hardware has something to offer over the other systems available. If these aditional features are not going to be used, there is no point in buying "proprietry" hardware. It is a bit like buying a car with sat nav, and then refusing to use the sat nav because it is not standard in other cars!!

I am all in favour of using all the features of the hardware and software available, and "IF" the business decides it wants to change platform at at some future date, then that is a separate probem, an entirely different project, and an entirely different budget.

IBM's system i is a superb computer system, with a top class operating system in i5/OS. It would be a shame to waste it.

By tying your code into the platform you lose modularity and agility.
That is the strength of modular programming, and that is why nearly
everything on Unix/Linux/PASE and even windows, uses stdout and stdin
along with piping and redirection.

your php script does something and writes the result to stdout. At
some point you may want to deploy your code on another non i platform,
or may want to do something else based on the output.

[WEB400] Getting PHP to write back to a data queue






It is actually simpler than it seems. The xargs utility is great at
intercepting standard output and doing stuff with it, like passing it
to another program.

Step 1: Write a CL program wrapper for the QSNDDTAQ API. Let's call it
P1 and let it accept a string and a queue name.
Step 2: pipe the stdout of the php script to the xargs PASE tool, like
this:

yourPHPscript.sh | xargs -i system "call P1 '{}' queuename"

I like this approach because it promotes writing modular programs,
although there is a slight performance penalty.
