Need PHP help parsing CGI response...

I have a form that submits to a PHP script which in turn does a shell_exec to a perl script written by someone else, which calls an API to validate the form data. The pastie is the exact response I am given when a user is not authenticated. This should be very easy for someone to figure out, but I'm on a time crunch to get this done by end of day so I need to know how to parse out each field.

Specifically, at the bottom of the response is a 'data' => '0' -- it could potentially be '1' but that shouldn't matter for these purposes. However, I want to be able to know what that value is. I also want to know what the value of the errors[{'messages'}] is *if* it exists (sometimes it won't be there, that's ok).

So in essence, I want to be able to say if (blah['data'] == '0') then do something otherwise do something else.

TIA,
Jen
<?php
$output = shell_exec('login.pl test test');
// echo $output gives: 
$VAR1 = bless( {
  'warnings' => [],
  'errors' => [
    {
      'data' => '',
      'message' => 'Customer/password combination is invalid',
      'code' => '1997'
    }
  ],
  '_warn_table' => undef,
  '_err_table' => undef,
  'multicall' => 0,
  'data' => '0'
}, 
'VWH::API::Return');
?>

Bless is not a PHP function - it is a PERL/CGI function

http://us.php.net/manual/en/arrayobject.construct.php

Try array function instead:
<?php
$output = shell_exec('login.pl test test');
// echo $output gives: 
$VAR1 = array( {
  'warnings' => [],
  'errors' => [
    {
      'data' => '',
      'message' => 'Customer/password combination is invalid',
      'code' => '1997'
    }
  ],
  '_warn_table' => undef,
  '_err_table' => undef,
  'multicall' => 0,
  'data' => '0'
}, 
'VWH::API::Return');
?>

$VAR1 ['data'];

$value_data = array_search('data', $VAR1);
if ($value_data == 1){
// DATA == 1
} else {
// DATA == NOT 1
}
