Looking for a sample to execute PHP using Execute Program

Question

I'm looking for a sample to execute PHP (Skripts) using "Execute Program". Current I get some error. Rapidminer can't find php. Please look at images.

Thanks,

Thomas

Thanks Jan. Thats true, but my problem is, that PHP don't find the PIPE Data from "Write CSV".

1) Model Looks like attached image..

2) parameter from Execute Program looks like..

command: cmd /c  start D: \Wiedmann\Tools\php-5.6.13-Win32-VC11-x86apidminer-start-php.bat

working directory: D: \Wiedmann\Tools\php-5.6.13-Win32-VC11-x86\

3) rapidminer-start-php.bat looks like

rem --- rapidminer-start-php.bat ---
d:
cd d:\wiedmann	ools\php-5.6.13-Win32-VC11-x86
php rapidminer.php

4) rapidminer.php looks like..

<?php
 echo 'start php';

// $data = stream_get_contents(STDIN);
 $data = array();

// https://stackoverflow.com/questions/5891888/piping-data-into-command-line-php
 // TEST $fp = readfile("php://stdin");

echo 'start php-2';
 while($f = fgets(STDIN)){
     echo "line: $f";
     $data[] = $f;
 }

echo 'start php-3';
 var_dump($data);

sort($data);
 echo 'start php-4';

if (empty($data)) {
  $data = array ( 1, 2, 3 );
 }
 echo 'start php-5';

fwrite(STDOUT, implode(';',$data));

echo 'start php-6';

?>

Problem:

PHP get no piped information. PHP ist readin on STDIN and wait forever. My breakpoint after shows me this Box

PHP script is still waiting on echo "php-2" forever. PHP waits on console INPUT.

Big Question: Why "Write CSV" Data are not piped to "Execute Program" ?

EDIT

This for example work well and PHP get piped data from dir.

D: \Wiedmann\Tools\php-5.6.13-Win32-VC11-x86>dir | php rapidminer.php

Hi Thomas, from my experience it is like this: If you can execute that script in your normal Windows cmd, then it should also be able to run from within RapidMiner. Can you tell a little bit more of your setup? Which Windows version are you using? Is the path you posted your project or your php installation directory? I would think that something like C:\\php \rapidminer.php should work. Cheers Jan

may this

cmd /c start  "php -f rapidminer.php"

but my php skript did'nt start. Maybe I get empty CMD console, but php did'nt run the script.

Seems difficult. Any comment?
