For details on supported options, see
 » Connection String Options in the MongoDB manual. 
» Connection pool options are not supported, as the PHP driver does not implement connection pools.

The PHP driver uses libmongoc's single-threaded client mode, which does not implement connection pools. There is also no way to implement your own connection pooling using this driver.

Each single-threaded libmongoc client object maintains at most one socket connection per mongod or mongos server. The relationship between MongoDB\Driver\Manager objects and libmongoc client objects is discussed in Connection Handling in the driver documentation.

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.
