Detailed technical documentation on using RudderStack’s PHP SDK to send events to various destinations

RudderStack’s PHP SDK allows you to track your customer event data from your PHP code. Once enabled, the event requests hit the RudderStack servers. RudderStack then routes the events to the specified destination platforms as configured by you.
You can find this SDK in our GitHub repository.
Installing the RudderStack PHP SDK
Install the RudderStack PHP SDK using the composer. You can also do so by running the following command:
git clone https://github.com/rudderlabs/rudder-sdk-php /my/app/folders/
Initializing the RudderStack Client
To initialize the RudderStack client, run the following code snippet:
require_once("/path/to/lib/Rudder.php");
​
Rudder::init(WRITE_KEY, array(
  "data_plane_url" => DATA_PLANE_URL,
  "consumer"       => "lib_curl", // fork_curl
  "debug"          => true,
  "max_queue_size" => 10000,
  "batch_size"     => 100
));
Sending Events from RudderStack
Once the RudderStack client is initialized, you can use it to send relevant customer events from the RudderStack client. An example track call is as shown in the following code snippet:
Rudder::track(array(
  "userId" => "f4ca124298",
