PHP 7.0.6 Released

    The MongoDuplicateKeyException class

    (PECL mongo >= 1.5.0)

    Introduction

    Thrown when attempting to insert a document into a collection which already contains the same values for the unique keys.

    Class synopsis

    MongoDuplicateKeyException extends MongoWriteConcernException {
    /* Inherited properties */
    protected string $message ;
    protected int $code ;
    protected string $file ;
    protected int $line ;
    /* Inherited methods */
    public array MongoWriteConcernException::getDocument ( void )
    }

    Examples

    Example #1 Catching MongoDuplicateKeyException

    <?php
    $mc     = new MongoClient("localhost");

    $c = $mc->selectCollection("test", "test");

    $c->insert(array('_id' => 1));
    try {
            $c->insert(array('_id' => 1));
    } catch (    MongoWriteConcernException $e) {
        echo     $e->getMessage(), "\n";
    }
    ?>

    The above examples will output something similar to:

    localhost:27017: insertDocument :: caused by :: 11000 E11000 duplicate key error index: test.test.$_id_  dup key: { : 1 }
