MongoPool::setSizeSet the size for future connection pools


public static MongoPool::setSize ( int $size ) : bool

Sets the max number of connections new pools will be able to create.



The max number of connections future pools will be able to create. Negative numbers mean that the pool will spawn an infinite number of connections.

Valor Retornado

Returns the former value of pool size.


Versão Descrição
1.2.11 Emits E_DEPRECATED when used.


Exemplo #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.


// only allow one connection to a server

// 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();


O exemplo acima irá imprimir algo similar à:

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
