The MongoProtocolException class

(PECL mongo >= 1.5.0)

Introdução

When talking to MongoDB 2.6.0, and later, certain operations (such as writes) may throw MongoProtocolException when the response from the server did not make sense - for example during network failure (we could read the entire response) or data corruption.

This exception is also thrown when attempting to talk newer protocols then the server supports, for example using the MongoWriteBatch when talking to a MongoDB server prior to 2.6.0.

Sinopse da classe

MongoProtocolException extends MongoException {
/* Propriedades herdadas */
protected string $message ;
protected int $code ;
protected string $file ;
protected int $line ;
}

Exemplos

Exemplo #1 Catching MongoProtocolException

Running the following example against MongoDB prior to 2.6.0 will throw an MongoProtocolException

<?php
$mc 
= new MongoClient("localhost");
$c $mc->selectCollection("test""test");

try {
    
$batch = new MongoInsertBatch($c);
} catch(
MongoProtocolException $e) {
    echo 
$e->getMessage();
}
?>
