What are the best practices for retrieving information about methods, traits, and classes in PHP?

When working with PHP, it's important to have a good understanding of the methods, traits, and classes available in a given codebase. One way to retrieve information about these elements is by using reflection. PHP's reflection API allows you to inspect classes, methods, and traits at runtime, providing valuable information such as method signatures, parameter types, and class hierarchy. 

// Retrieve information about a class using reflection
$class = new ReflectionClass('ClassName');
$methods = $class->getMethods();
$traits = $class->getTraits();

// Iterate over the methods and traits
foreach ($methods as $method) {
    echo $method->getName() . "\n";
}

foreach ($traits as $trait) {
    echo $trait->getName() . "\n";
}
