Running a ruby script from php

Question

Ruby is installed here:

.rvm/rubies/ruby-2.2.1/bin

Ruby script:

puts "Hello world"

Php script:

<?php
    $cmd = "ruby /home/balint/rubytest.rb";     
    echo system($cmd);
?>

I can run sudo php /home/name/public_html/phprubytest.php from CLI but not from the browser.

I reach the server via Putty and use Filezilla to put all my website-related files to the public_html folder.

I logged out the error and it turned out I have a permission error:

ruby: Permission denied -- /home/balint/rubytest.rb (LoadError)

This means as a user running the php script from the browser I have no access to that directory on the server.

Any ideas?

That is a fantastic tutorial to send and receive data and that's where I come from. I tried it, received command returned 1 message so I decided to try out the simple script. And here I am now. — erdomester

Looks like you're not allowed to read that file as the user running the PHP script. — tadman

That's right. It has -rw-rw-r-- permissions. What I did is that I copied it into the public_html folder where I have permission to run it. However, in order to run the ruby script now from php I should add the absolute path of all the gems that I use. What's the better way here, solving the permission issue or setting path for all gems? — erdomester

exec(rubyfile.rb);

Just add this code and it will execute your ruby file.
