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

Description

public int MongoCursor::count ([ boolean $foundOnly = FALSE ] )

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 exhasted the cursor, it will not reset it.

Parameters

foundOnly

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

Return Values

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

Examples

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));

?>

The above example will output something similar to:

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