class MyClass { public function myMethod() { echo "Hello World!"; } } $reflectionMethod = new ReflectionMethod('MyClass', 'myMethod'); $fileName = $reflectionMethod->getFileName(); echo $fileName; // outputs /path/to/MyClass.php
class Greeting { public function sayHello() { echo "Hello World!"; } } $reflectionMethod = new ReflectionMethod('Greeting', 'sayHello'); $fileName = $reflectionMethod->getFileName(); $packageName = substr($fileName, 0, strpos($fileName, 'src/') + 4); echo $packageName; // outputs myPackage/src/In this example, we create a ReflectionMethod object of the sayHello method in Greeting class and then use getFileName to get the file name where the method is defined. We then use the file name to determine the package/library name by extracting the string before the src/ directory. Based on the examples, it seems like the ReflectionMethod class is part of the core PHP library, rather than a package or external library.
