ReflectionParameter::getClass() will cause a fatal error (and trigger __autoload) if the class required by the parameter is not defined.

Sometimes it's useful to only know the class name without needing the class to be loaded.

Here's a simple function that will retrieve only the class name without requiring the class to exist:

<?php
function getClassName(ReflectionParameter $param) {
   
preg_match('/\[\s\<\w+?>\s([\w]+)/s', $param->__toString(), $matches);
    return isset(
$matches[1]) ? $matches[1] : null;
}
?>

The method returns ReflectionClass object of parameter type class or NULL if none.

<?php

class A {
    function
b(B $c, array $d, $e) {
    }
}
class
B {
}

$refl = new ReflectionClass('A');
$par = $refl->getMethod('b')->getParameters();

var_dump($par[0]->getClass()->getName());  // outputs B
var_dump($par[1]->getClass());  // note that array type outputs NULL
var_dump($par[2]->getClass());  // outputs NULL

?>
