This PR results from a discussion we had yesterday with @alcaeus, @beberlei and others at the Symfony UG meetup in Berlin (thanks SensioLabs for bringing me there).
It provides a generic function and convention to trigger deprecation notices, which could be a better alternative to the `@trigger_error(..., E_USER_DEPRECATED)` calls that we use currently.
This proposed package would provide a single global function named `deprecated()`.
Its purpose is to trigger deprecations in a way that can be silenced on production environment
by using the `zend.assertions` ini setting and that can be caught during development to generate reports.
The function requires at least 3 arguments:
- the name of the package that is triggering the deprecation
- the version of the package that introduced the deprecation
- the message of the deprecation
- more arguments can be provided: they will be inserted in the message using `printf()` formatting
Example:
```php
deprecated('symfony/blockchain', 8.9, 'Using "%s" is deprecated, use "%s" instead.', 'bitcoin', 'fabcoin');
```
This will generate the following message:
`Since symfony/blockchain 8.9: Using "bitcoin" is deprecated, use "fabcoin" instead.`
Check #35550 to see how using this function could look like on Symfony itself.
