What will be the output of the following PHP code?

<?php 
$states = array(
    "Karnataka" => array(
        "population" => "11,35,000", 
        "capital" => "Bangalore"), 
    "Tamil Nadu" => array(
        "population" => "17,90,000", 
        "capital" => "Chennai")
    );
echo $states["Karnataka"]["population"];
?>
