Beschreibung

Warnung

This method has been DEPRECATED as of version 1.2.3. Relying on this feature is highly discouraged. Please use MongoPool::setSize instead.

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

Parameter-Liste

size: 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.

Rückgabewerte

Returns the former value of pool size.

Beispiele

Beispiel #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
Mongo::setPoolSize(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();

?>

Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:

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
