Примеры
Пример #1 Mongo::setPoolSize() example
If you set the pool size to n and then create n connections, attempting to create an n+1st connection will throw a MongoConnectionException.
<?php
// only allow one connection to a server
MongoPool::setSize(1);
// creates one connection to localhost:27017
$m1 = new Mongo();
// attempt to create a second connection to localhost:27017
// only one connection is allowed, so this will throw an exception
$m2 = new Mongo();
?>
Результатом выполнения данного примера будет что-то подобное:
