If there is Early Adopter support for a PHP version, it has a separate switch that enables you to opt in or out of monitoring for that version.
To enable an Early Adopter release of PHP monitoring in Dynatrace
Go to Settings and select Monitoring > Monitored technologies.
On the Supported technologies tab, find PHP and open it for editing.
On the PHP page, turn on Enable PHP x monitoring on every host.
Verify that your monitoring environment meets the requirements stated under the switch.
When OneAgent detects an unsupported PHP version, we exclude it from monitoring and display a warning in the process overview page:
Activation of deep monitoring was unsuccessfulProcess version is not supported

We also write the message to the error logs on the host machine.
See the environments and versions that Dynatrace supports in conjunction with PHP and the PHP supported versions.
