PHP Mongodb驱动1.5:如何使用连接池?

I'm using PHPLIB 1.4 + PHP mongodb-1.5(PECL). How to set up connection pool? I searched but all results are for older version.

    The PHP driver uses libmongoc's single-threaded client mode, which does not implement connection pools.

    See mongo-php-driver: issues#688:

    Connection pools should not be needed for any single-threaded application, unless you're using an async PHP framework (e.g. Amp, ReactPHP). In those cases, you'd probably need to implement your own driver as we provide no way to integrate libmongoc's IO with a PHP event loop. Multi-threaded PHP applications (e.g. pthreads, forking) are not supported by the driver.

    Instead of connection pooling, the PHP driver uses connection and topology persistence since version 1.2.0+.

    When MongoDB\Driver\Manager::__construct() is invoked, a hash is created from its arguments (i.e. URI string and array options). The driver will attempt to find a previously persisted libmongoc client object for that hash. If an existing client cannot be found for the hash, a new client will be created (and persisted for future use).

    See more information MongoDB PHP Connection Handling.
