Examples
Example #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();
?>
The above example will output something similar to:
Fatal error: Uncaught exception 'MongoConnectionException' with message 'no more connections in pool' in /path/to/php/script.php:10
Stack trace:
#0 /path/to/php/script.php(10): Mongo->__construct()
#1 {main}
thrown in /path/to/php/script.php on line 10
