boolean

[King Kovifor]

In PHP, when I write this in a plugin:

PHP Code:

if (THIS_SCRIPT == "index")
{
    global $globaltemplates;

 if ($vbulletin->$options[option] == "1")
   {
    $globaltemplates = array_merge($globaltemplates, array('template'));
   }
 if ($vbulletin->$options[option] == "0")
   {
    $globaltemplates = array_merge($globaltemplates, array('second_template'));
   }
} 


What would be the $vbulletin->$options[option] have to equal to be true and false in a boolean mode?
