Check if variable in other class is set true

[itsme85]

Hello,

I want to check if a variable in a other class is set "true".

<?php
class test
{
    var $a=true;

function create()
{
}
}

$obj =new test;
if ( property_exists( $obj, 'a' ) )
{
    echo 'The property "a" exsists';
}
else
{
    echo 'The property "a" does not exsist';
}
?> 

How can do that?

<?php
class test
{
    var $a=true;

function create()
{
}
}

$obj = new test;
if($obj->a == true)
{
   echo "It is true";
}
else
{
   echo "It is NOT true";
}
