    MongoCursor::count — Counts the number of results for this query

    Descrierea

    public MongoCursor::count ( bool $foundOnly = false ) : int

    This method does not affect the state of the cursor: if you haven't queried yet, you can still apply limits, skips, etc. If you have started iterating through results, it will not move the current position of the cursor. If you have exhausted the cursor, it will not reset it.

    Parametri

    foundOnly

    Send cursor limit and skip information to the count function, if applicable.

    Valorile întoarse

    The number of documents returned by this cursor's query.

    Exemple

    Example #1 MongoCursor::count() example

    <?php

    $collection    ->insert(array('x'=>1));
    $collection->insert(array('x'=>2));
    $collection->insert(array('x'=>3));

    $cursor = $collection->find();

    var_dump($cursor->count());
    var_dump($cursor->count(true));

    $cursor->limit(2);

    var_dump($cursor->count());
    var_dump($cursor->count(true));

    ?>

    Exemplul de mai sus va afișa ceva similar cu:

    int(3)
int(3)
int(3)
int(2)
