" was triggered " . $count . " times\n"; } ``` ### Suppressing Specific Deprecations Disable triggering about specific deprecations: ```php \Doctrine\Deprecations\Deprecation::ignoreDeprecations("https://link/to/deprecations-description-identifier"); ``` Disable all deprecations from a package ```php \Doctrine\Deprecations\Deprecation::ignorePackage("doctrine/orm"); ``` ### Other Operations When used within PHPUnit or other tools that could collect multiple instances of the same deprecations the deduplication can be disabled: ```php \Doctrine\Deprecations\Deprecation::withoutDeduplication(); ``` Disable deprecation tracking again: ```php \Doctrine\Deprecations\Deprecation::disable(); ``` ## Usage from a library/producer perspective: When you want to unconditionally trigger a deprecation even when called from the library itself then the `trigger` method is the way to go: ```php \Doctrine\Deprecations\Deprecation::trigger( "doctrine/orm", "https://link/to/deprecations-description", "message" ); ``` If variable arguments are provided at the end, they are used with `sprintf` on the message. ```php \Doctrine\Deprecations\Deprecation::trigger( "doctrine/orm", "https://github.com/doctrine/orm/issue/1234", "message %s %d", "foo", 1234 ); ``` When you want to trigger a deprecation only when it is called by a function outside of the current package, but not trigger when the package itself is the cause, then use: ```php \Doctrine\Deprecations\Deprecation::triggerIfCalledFromOutside( "doctrine/orm", "https://link/to/deprecations-description", "message" ); ``` Based on the issue link each deprecation message is only triggered once per request. A limited stacktrace is included in the deprecation message to find the offending location. Note: A producer/library should never call `Deprecation::enableWith` methods and leave the decision how to handle deprecations to application and frameworks. ## Usage in PHPUnit tests There is a `VerifyDeprecations` trait that you can use to make assertions on the occurrence of deprecations within a test. ```php use Doctrine\Deprecations\PHPUnit\VerifyDeprecations; class MyTest extends TestCase { use VerifyDeprecations; public function testSomethingDeprecation() { $this->expectDeprecationWithIdentifier('https://github.com/doctrine/orm/issue/1234'); triggerTheCodeWithDeprecation(); } } ``` ## What is a deprecation identifier? An identifier for deprecations is just a link to any resource, most often a Github Issue or Pull Request explaining the deprecation and potentially its alternative.
