Newbie Associative Array Question

[JerryH]

Here is my array:

$option = array (
'fruit' => array ('banana','apple'),
'vegetable' => array ('cucumber','lettuce'),
'nut' => array ('almond','peanut')
);

All I want to do is print the second key. How can I write this?

<?php print $option[key[1]] ?>

I want the above to print out 'vegetable'.

You want to use the array_keys() function:

$option = array (
'fruit' => array ('banana','apple'),
'vegetable' => array ('cucumber','lettuce'),
'nut' => array ('almond','peanut')
);

$option_keys = array_keys($option);
echo $option_keys[1];

Remember that arrays (non-associative) start with the index 0.
