PHP How can get the namespace of class method parameter?

Hello i try many things to catch the namespace of an parameter function but nothing.

public function table(Homes $homes) { // <---------- Homes
    return $homes->get('home');
}

I try with ReflectionClass but give me only the name $homes not the Homes namespace.

Solution

  • It's possible:

    $method         = new ReflectionMethod('classDeclaringMethodTable', 'table');

// ReflectionMethod::getParameters() returns an *array*
// of ReflectionParameter instances; get the first one
$parameter      = $declaringMethod->getParameters()[0];

// Get a ReflectionClass instance for the parameter hint
$parameterClass = $parameter->getClass();

    And then at this point, it depends on exactly what you want ...

    // Returns ONLY the namespace under which class Homes was declared
$parameterClass->getNamespaceName();

// Returns the fully qualified class name of Homes
// (i.e. namespace + original name; it may've been aliased)
$parameterClass->getName();

    I've used multiple variables to make it easier to follow, but it can easily be a one-liner with method chaining.
