Problem regarding arrays PHP

Question

<?php
$people = array(
'online'=>array('David', 'Amy'),
'offline'=>array('John', 'Rob', 'Jack'),
'away'=>array('Arthur', 'is'),
'busy'=>('Godlike')
);

echo $people['online'][0];
echo "<br />";
echo $people['away'][1];
echo "<br />";
echo $people['busy'][0];

?>

I know that i did not put array after busy but someone can explains me why it is showing me just G ? ( the first letter of godlike ).

Answer 1

A string is similar to an array in that you can use square brackets to get individual characters.

$people["busy"] gives you the string "Godlike" (not the array ["Godlike"] as you pointed out), so $people["busy"][0] gives you the first element of "Godlike" which is 'G'!
