Here's an appropriate example, one of a few ways you may do it :
$state = 'Wa';
$state = trim(strtoupper($state));
$states = array('WA' => 'Washington', 'OR' => 'Oregon', 'ID' => 'Idaho');
if (in_array($state, array_keys($states))) {
echo "you chose <b>{$states[$state]}</b>, a state in the pacific NW!";
} else {
echo "you've chosen <b>$state</b>, an inferior state indeed.";
}
In the above, we make sure the chosen state is a $states key/index as
array_keys creates an array of keys, from the $states array, like so :
$keys = array('WA','OR','ID');
If $state is in this array, bingo! That's one way, it all depends on what
you're doing exactly. in_array() is a nice little function btw, that's
the point of this post :) Check out array_keys and array_search too.
