Answer by daanl for PHP Reflection - Get Method Parameter Type As String

I had similar problem, when checking getClass on reflection parameter when a class was not loaded. I made a wrapper function to get the class name from example netcoder made. Problem was that netcoder code didnt work if it was an array or not an class -> function($test) {} it would return the to string method for the reflection parameter.

Below the way how i solved it, im using try catch because my code requires at some point the class. So if i request it the next time, get class works and doesnt throw an exception.

/**
 * Because it could be that reflection parameter ->getClass() will try to load an class that isnt included yet
 * It could thrown an Exception, the way to find out what the class name is by parsing the reflection parameter
 * God knows why they didn't add getClassName() on reflection parameter.
 * @param ReflectionParameter $reflectionParameter
 * @return string Class Name
 */
public function ResolveParameterClassName(ReflectionParameter $reflectionParameter)
{
    $className = null;

    try
    {
                 // first try it on the normal way if the class is loaded then everything should go ok
        $className = $reflectionParameter->getClass()->name;

    }
    // if the class isnt loaded it throws an exception and try to resolve it the ugly way
    catch (Exception $exception)
    {
        if ($reflectionParameter->isArray())
        {
            return null;
        }

        $reflectionString = $reflectionParameter->__toString();
        $searchPattern = '/^Parameter \#' . $reflectionParameter->getPosition() . ' \[ \<required\> ([A-Za-z]+) \$' . $reflectionParameter->getName() . ' \]$/';

        $matchResult = preg_match($searchPattern, $reflectionString, $matches);

        if (!$matchResult)
        {
            return null;
        }

        $className = array_pop($matches);
    }

    return $className;
}
