Query on PHP arrays

Question

Consider following scenario: You have a small MogoDB collection or a small MySQL table (contains 1000 record for example, it may be read-only too ) that is used extensively and repeatedly in your app.

You decide to fetch all of its content to a PHP array and use the array instead of sending a lot of query to DB.

In above scenario how can we retrieve some array items in a manner similar to retrieving records of a DB table in an efficient way? A PDO adapter for array or any other similar facility ...

Answer 1

Simple example

// Create data source
$names = array("John", "Peter", "Joe", "Patrick", "Donald", "Eric"); 

$result = from('$name')->in($names)
            ->where('$name => strlen($name) < 5')
            ->select('$name');
