I'm sure there is an easy way to do this, but I can't think of it right now. Is there an array function or something that lets me search through an array and find the item that has a certain property value? For example:

$people = array(
  array(
    'name' => 'Alice',
    'age' => 25,
  ),
  array(
    'name' => 'Waldo',
    'age' => 89,
  ),
  array(
    'name' => 'Bob',
    'age' => 27,
  ),
);

How can I find and get Waldo?
