how do i pass php array’s to ruby script as an argument so that ruby script can read php’s array. ?

Answer 1

You could use JSON:

$ cat f1.php
<?php
$a = array(1, 2, 3);
$cmd = 'ruby f2.rb \'' . json_encode($a) . '\'';
printf("%s\n", `$cmd`);
?>
$ cat f2.rb
require 'rubygems'
require 'json'

s = JSON.parse ARGV[0]
puts s
puts s.class
$ php f1.php
1
2
3
Array
