Executing Ruby script from PHP and getting output

Question

I have this Ruby script (test.rb):

print "hello"

And I have this PHP script (test.php):

$cmd = "ruby test.rb";
system($cmd);

Now I call my PHP script from CLI this way:

php test.php

And I get no output (it should print "hello")

Why?

I don't know about the PHP, but you probably want puts "Hello". print does not include a newline. — Linuxios

system would capture the output of the ruby script.

you might want to do:

$cmd = "ruby test.rb";
echo system($cmd);

yes, OK, without the echo is working fine, the PHP CLI I was using was misconfigured, but now I have open another question with the real problem: stackoverflow.com/questions/8604637/…

Its working for me, check whether both ruby script and php in the same folder and installed ruby in your machine

<?php
$cmd = "ruby test.rb";     
system($cmd);
?>
