What happened

When configuring your PHP project to use the skywalking_agent with php.ini to send data to Kafka, and especially when setting up SASL authentication, you've encountered an issue related to the SASL mechanism. Here's a breakdown of your situation in English:

1.SASL Mechanism Set to PLAIN: When the sasl.mechanism is set to PLAIN, the overall process works without any issues.

2.SASL Mechanism Set to SCRAM-SHA-256: When changing the sasl.mechanism to SCRAM-SHA-256, an error is reported: ERROR skywalking_agent::worker: worker exit unexpectedly err=Client creation error: No provider for SASL mechanism SCRAM-SHA-256: recompile librdkafka with libsasl2 or openssl support. Current build options: PLAIN

Despite recompiling librdkafka and confirming the presence of sasl_scram support through the example tool, the skywalking_agent in your PHP project continues to throw an error indicating that there's no provider for the SCRAM-SHA-256 SASL mechanism.

What you expected to happen

Whether the existing php skywalking_agent plugin supports the SCRAM-SHA-256 authentication method is a questio
