Conditional Runtime PHP Extension loading

Description

I would like to build a docker container with various PHP extensions and be able to toggle them off with environment variables. (OpenTelemetry / XDebug / Tideways / Blackfire does not like each other). Of course I can build various tags, but it's an hassle of CI managment.

The solution who most people are doing is to use the docker entrypoint to move files to disable loading of extensions. This does not work when the container is read-only. Therefore I would suggest to have some kind of environment variable to disable / enable extension on the fly.

Several ideas I had so far:

in php.ini

{if hasEnv("FOO")}
extension=foo.so
{/if}

so we can toggle even php.ini settings

or a simple

PHP_EXTENSIONS_DISABLE=opentelemetry

L’issue non indica file di implementazione, test o punti di ingresso. Inizia tracciando il caricamento delle estensioni e la gestione della configurazione di PHP, quindi determina come debba funzionare l’abilitazione o la disabilitazione basata sull’ambiente, incluse le condizionali php.ini proposte. Il lavoro sarà considerato completato quando un design concordato sarà implementato e coperto per i container di sola lettura e per il cambio delle estensioni a runtime.
