[Bug]: receive appsec warning

[Damien-DAGORN]

Bug report

Since 2 days I receive these messages from my php app, I've tried to disable appsec explicitly by set the "DD_APPSEC_ENABLED" env var to false but it doesn't work and we continue to receive the message.

• NOTICE: PHP message: PHP Warning: Unknown: [ddappsec] Invalid message header from helper in Unknown on line 0
• NOTICE: PHP message: PHP Warning: Unknown: [ddappsec] Error receiving reply for command config_sync: dd_network in Unknown on line 0

DD_APPSEC_ENABLED=false should definitely prevent appsec from trying to connect. Check phpinfo() and verify the value of datadog.appsec.enabled. Maybe the environment variable is not being set in the correct context. The fact that appsec is trying to send a config_sync message suggests that DD_APPSEC_ENABLED is in its default state (neither true nor false).

You may also choose not to load the ddappsec.so shared library (remove extension=ddappsec.so from the php configuration).
