Warning: ClassName::method(): OpenTelemetry: WithSpan attribute found but attribute hooks disabled in Unknown on line 0

Describe your environment

When ext-opentelemetry is enabled and codebase has classes with #[WithSpan] attribute, opentelemetry.attr_hooks_enabled = On also needs to be set. Otherwise, the following warning is thrown in runtime:

Warning: ClassName::method(): OpenTelemetry: WithSpan attribute found but attribute hooks disabled in Unknown on line 0

It's fine having opentelemetry.attr_hooks_enabled = On in the running code, however, PHPUnit will crash with a nebulous segfault:

zsh: trace trap  ./vendor/bin/phpunit tests/

Steps to reproduce

PHP 8.2.27
PHPUnit 10.5.40

php.ini

opentelemetry.attr_hooks_enabled = On

What is the expected behavior?

Disable warning or hooks in some way and not trigger warning

What is the actual behavior?

Unless I delete #[WithSpan] attributes or disable ext-opentelemetry altogether, there is no way to fix this.

Hi @rauanmayemir thanks for the bug report. It sounds reasonable that warnings like this should be controllable (perhaps behind a config and off by default).
