MongoDB\Driver\Manager::__construct

参数

uri

A » mongodb:// connection URI:

mongodb://[username:password@]host1[:port1][,host2[:port2],...[,hostN[:portN]]][/[database][?options]]

For details on supported options, see » Connection String Options in the MongoDB manual. » Connection pool options are not supported, as the PHP driver does not implement connection pools.

The uri is a URL, hence any special characters in its components need to be URL encoded according to » RFC 3986. This is particularly relevant to the username and password, which can often include special characters such as @, :, or %. When connecting via a Unix domain socket, the socket path may contain special characters such as slashes and must be encoded. The rawurlencode() function may be used to encode constituent parts of the URI.

uriOptions

Additional » connection string options, which will overwrite any options with the same name in the uri parameter.

uriOptions

Option	Type	Description
appname	string	MongoDB 3.4+ has the ability to annotate connections with metadata provided by the connecting client. This metadata is included in the server's logs upon establishing a connection and also recorded in slow query logs when database profiling is enabled. This option may be used to specify an application name, which will be included in the metadata. The value cannot exceed 128 characters in length.
authMechanism	string	The authentication mechanism that MongoDB will use to authenticate the connection. For additional details and a list of supported values, see » Authentication Options in the MongoDB manual.
authMechanismProperties	array	Properties for the selected authentication mechanism. For additional details and a list of supported properties, see the » Driver Authentication Specification. Note: When not specified in the URI string, this option is expressed as an array of key/value pairs. The keys and values in this array should be strings.
authSource	string	The database name associated with the user's credentials. Defaults to the database component of the connection URI. For authentication mechanisms that delegate credential storage to other services (e.g. GSSAPI), this should be "$external".
canonicalizeHostname	boolean	If TRUE, the driver will resolve the real hostname for the server IP address before authenticating via SASL. Some underlying GSSAPI layers already do this, but the functionality may be disabled in their config (e.g. krb.conf). Defaults to FALSE. This option is a deprecated alias for the "CANONICALIZE_HOST_NAME" property of the "authMechanismProperties" URI option.
compressors	string	A prioritized, comma-delimited list of compressors that the client wants to use. Messages are only compressed if the client and server share any compressors in common, and the compressor used in each direction will depend on the individual configuration of the server or driver. See the » Driver Compression Specification for more information.
connectTimeoutMS	integer	The time in milliseconds to attempt a connection before timing out. Defaults to 10,000 milliseconds.
gssapiServiceName	string	Set the Kerberos service name when connecting to Kerberized MongoDB instances. This value must match the service name set on MongoDB instances (i.e. » saslServiceName server parameter). Defaults to "mongodb". This option is a deprecated alias for the "SERVICE_NAME" property of the "authMechanismProperties" URI option.
heartbeatFrequencyMS	integer	Specifies the interval in milliseconds between the driver's checks of the MongoDB topology, counted from the end of the previous check until the beginning of the next one. Defaults to 60,000 milliseconds. Per the » Server Discovery and Monitoring Specification, this value cannot be less than 500 milliseconds.
journal	boolean	Corresponds to the default write concern's journal parameter. If TRUE, writes will require acknowledgement from MongoDB that the operation has been written to the journal. For details, see MongoDB\Driver\WriteConcern.
localThresholdMS	integer	The size in milliseconds of the latency window for selecting among multiple suitable MongoDB instances while resolving a read preference. Defaults to 15 milliseconds.
maxStalenessSeconds	integer	Corresponds to the read preference's "maxStalenessSeconds". Specifies, in seconds, how stale a secondary can be before the client stops using it for read operations. By default, there is no maximum staleness and clients will not consider a secondary’s lag when choosing where to direct a read operation. For details, see MongoDB\Driver\ReadPreference. If specified, the max staleness must be a signed 32-bit integer greater than or equal to MongoDB\Driver\ReadPreference::SMALLEST_MAX_STALENESS_SECONDS (i.e. 90 seconds).
password	string	The password for the user being authenticated. This option is useful if the password contains special characters, which would otherwise need to be URL encoded for the connection URI.
readConcernLevel	string	Corresponds to the read concern's level parameter. Specifies the level of read isolation. For details, see MongoDB\Driver\ReadConcern.
readPreference	string	Corresponds to the read preferences's mode parameter. Defaults to "primary". For details, see MongoDB\Driver\ReadPreference.
readPreferenceTags	array	Corresponds to the read preferences's tagSets parameter. Tag sets allow you to target read operations to specific members of a replica set. For details, see MongoDB\Driver\ReadPreference. Note: When not specified in the URI string, this option is expressed as an array consistent with the format expected by MongoDB\Driver\ReadPreference::__construct().
replicaSet	string	Specifies the name of the replica set.
retryWrites	boolean	If TRUE, the driver will automatically retry certain write operations that fail due to transient network errors or replica set elections. Defaults to FALSE. See » Retryable Writes in the MongoDB manual for more information.
safe	boolean	If TRUE, specifies 1 for the default write concern's w parameter. If FALSE, 0 is specified. For details, see MongoDB\Driver\WriteConcern. This option is deprecated and should not be used.
serverSelectionTimeoutMS	integer	Specifies how long in milliseconds to block for server selection before throwing an exception. Defaults to 30,000 milliseconds.
serverSelectionTryOnce	boolean	When TRUE, instructs the driver to scan the MongoDB deployment exactly once after server selection fails and then either select a server or raise an error. When FALSE, the driver blocks and searches for a server up to the "serverSelectionTimeoutMS" value. Defaults to TRUE.
slaveOk	boolean	Specifies "secondaryPreferred" for the read preference mode if TRUE. For details, see MongoDB\Driver\ReadPreference. This option is deprecated and should not be used.
socketCheckIntervalMS	integer	If a socket has not been used recently, the driver must check it via an isMaster command before using it for any operation. Defaults to 5,000 milliseconds.
socketTimeoutMS	integer	The time in milliseconds to attempt a send or receive on a socket before timing out. Defaults to 300,000 milliseconds (i.e. five minutes).
ssl	boolean	Initiates the connection with TLS/SSL if TRUE. Defaults to FALSE.
username	string	The username for the user being authenticated. This option is useful if the username contains special characters, which would otherwise need to be URL encoded for the connection URI.
w	integer|string	Corresponds to the default write concern's w parameter. For details, see MongoDB\Driver\WriteConcern.
wTimeoutMS	integer|string	Corresponds to the default write concern's wtimeout parameter. Specifies a time limit, in milliseconds, for the write concern. For details, see MongoDB\Driver\WriteConcern. If specified, wTimeoutMS must be a signed 32-bit integer greater than or equal to zero.
zlibCompressionLevel	integer	Specifies the compression level to use for the zlib compressor. This option has no effect if zlib is not included in the "compressors" URI option. See the » Driver Compression Specification for more information.

driverOptions

driverOptions

Option	Type	Description
allow_invalid_hostname	boolean	Disables hostname validation if TRUE. Defaults to FALSE. Allowing invalid hostnames may expose the driver to a » man-in-the-middle attack.
ca_dir	string	Path to a correctly hashed certificate directory. The system certificate store will be used by default. Falls back to the deprecated "capath" SSL context option if not specified.
ca_file	string	Path to a certificate authority file. The system certificate store will be used by default. Falls back to the deprecated "cafile" SSL context option if not specified.
crl_file	string	Path to a certificate revocation list file.
pem_file	string	Path to a PEM encoded certificate to use for client authentication. Falls back to the deprecated "local_cert" SSL context option if not specified.
pem_pwd	string	Passphrase for the PEM encoded certificate (if applicable). Falls back to the deprecated "passphrase" SSL context option if not specified.
context	resource	SSL context options to be used as fallbacks for other driver options (as specified). Note that the driver does not consult the default stream context. This option is supported for backwards compatibility, but should be considered deprecated.
weak_cert_validation	boolean	Disables certificate validation if TRUE. Defaults to FALSE Falls back to the deprecated "allow_self_signed" SSL context option if not specified.
