PHP

Scenarios

DDS allows you to perform data operations using PHP. You can connect to a DB instance through an SSL connection or a non-SSL connection. SSL connections provide stronger security.

By default, SSL is disabled for new DDS instances. For details about how to enable SSL, see Configuring SSL.

This section describes how to connect to a cluster instance using PHP.

Prerequisites

Ensure that the ECS can communicate with the DDS instance. To test the connectivity to the instance's IP address and port, run the curl command:
curl ip:port

If the message "It looks like you are trying to access MongoDB over HTTP on the native driver port." is displayed, the ECS and DDS instance can communicate with each other.
If SSL is enabled, you need to download the root certificate and upload it to the ECS.

Obtaining and Using the Driver

For PHP information, visit https://www.php.net/mongodb-driver-manager.construct.

Enabling and Disabling SSL

Run MongoDB\Client::__construct() to create a client instance.

function __construct(
	?string $uri = null, 
	array $uriOptions = [], 
	array $driverOptions = []
)

Use $uriOptions to set SSL to true to enable the SSL connection. Use $driverOptions to set ca_file to the CA certificate path and allow_invalid_hostname to true.
