Are there any best practices or recommended approaches for identifying the source file of a method in PHP, particularly when dealing with complex class hierarchies and Traits?

When dealing with complex class hierarchies and Traits in PHP, it can be challenging to identify the source file of a particular method. One recommended approach is to use the ReflectionClass and ReflectionMethod classes to inspect the class hierarchy and determine the source file of the method. 

function getSourceFileForMethod($class, $method) {
    $reflectionClass = new ReflectionClass($class);
    $reflectionMethod = $reflectionClass->getMethod($method);
    
    return $reflectionMethod->getFileName();
}

// Example usage
$sourceFile = getSourceFileForMethod('ClassName', 'methodName');
echo $sourceFile;
