    Exemplo #1 LimitIterator usage example

    <?php

    // Create an iterator to be limited
    $fruits = new ArrayIterator(array(
            'apple',
            'banana',
            'cherry',
            'damson',
            'elderberry'
    ));

    // Loop over first three fruits only
    foreach (new LimitIterator($fruits, 0, 3) as $fruit) {
            var_dump($fruit);
    }

    echo     "\n";

    // Loop from third fruit until the end
    // Note: offset starts from zero for apple
    foreach (new LimitIterator($fruits, 2) as $fruit) {
            var_dump($fruit);
    }

    ?>

    O exemplo acima irá imprimir:

    string(5) "apple"
string(6) "banana"
string(6) "cherry"

string(6) "cherry"
string(6) "damson"
string(10) "elderberry"
