Please help me resolve this error with my array...

I'm getting this error: " Notice: Array to string conversion in C:\xampp\htdocs\testsite.com\test.php on line 21 "

See code (please excuse messy testing code)

<?php
/*
$countries = array();
$countries["US"] = "United States"
$countries[]
*/

$country = array(
    "code" => "US",
    "name" => "United States",
    "capital" => "Washington, D.C.",
    "population" => 225000000,
    "anthem" => "The Star-Spangled Banner",
    "testolololo",  // < becomes indexed to $country[0]
);


?>


<?php $country[] = "this should come out when you call $country with key of 1";
?>

<br><br><br>Now I'm going to call $country[1], let's try it<br>
<?php echo $country[1]; ?>


<br><br><br>
<?php var_dump($country); ?>

IT works fine when I change $country[] = "" (on line 21) to almost any any other value!

But what's wrong with the string I have originally?

hey Andrew Zhao , from a quick look at your code snippet I would say that you're hitting this error because of the $country that you have in the text. as you're using double quotes php will interpret this as a variable, while you actually only want text. remove the dollar sign and and run your code again, if this works fine then you know for sure where the problem came from.

hope that helps and have a nice day ;)
