PHP执行Ruby脚本并捕获JSON结果

I have to work with a Ruby script that is dependent on a Gem. When the script is executed a JSON object is returned.

I am successfully executing the script using the following code.

<?php

$ruby = 'ruby ruby/teams.rb';

$res = system($ruby);

var_dump(json_decode($res, true));

The following is an example response from ruby/teams.rb

{"status"=>"active", "teamId"=>"XPLFKS59PK" }

My problem is that this printed directly to the screen and is not capture in the variable $res. When using var_dump(json_decode($res, true)) I get null.

What I would like to be able to do is capture the JSON response in the $res variable so I can convert to an array and worth with the data.

Any ideas if this is possible?

Most likely it sends its output to stderr instead stdout, so you need to redirect the streams yourself like this:

$ruby = 'ruby ruby/teams.rb 2>&1';

Here more about stream redirection: http://tldp.org/HOWTO/Bash-Prog-Intro-HOWTO-3.html

Or, use exec() instead of system()

system only returns the last line of the commands output. In your case, i would use exec. Your code would look something like below

$ruby = 'ruby ruby/teams.rb';
exec($ruby, $res);
var_dump(json_decode(implode("", $res), true));
