    Example #1 ReflectionMethod::__construct() example

    <?php
    class Counter
    {
    private static     $c = 0;


    final public static function increment()
    {
    return ++    self::$c;
    }
    }

    // Create an instance of the ReflectionMethod class
    $method = new ReflectionMethod('Counter', 'increment');

    // Print out basic information
    printf(
    "===> The %s%s%s%s%s%s%s method '%s' (which is %s)\n" .
    " declared in %s\n" .
    " lines %d to %d\n" .
    " having the modifiers %d[%s]\n",
    $method->isInternal() ? 'internal' : 'user-defined',
    $method->isAbstract() ? ' abstract' : '',
    $method->isFinal() ? ' final' : '',
    $method->isPublic() ? ' public' : '',
    $method->isPrivate() ? ' private' : '',
    $method->isProtected() ? ' protected' : '',
    $method->isStatic() ? ' static' : '',
    $method->getName(),
    $method->isConstructor() ? 'the constructor' : 'a regular method',
    $method->getFileName(),
    $method->getStartLine(),
    $method->getEndline(),
    $method->getModifiers(),
    implode(' ', Reflection::getModifierNames($method->getModifiers()))
    );

    // Print documentation comment
    printf("---> Documentation:\n %s\n", var_export($method->getDocComment(), true));

    // Print static variables if existant
    if ($statics= $method->getStaticVariables()) {
    printf("---> Static variables: %s\n", var_export($statics, true));
    }

    // Invoke the method
    printf("---> Invocation results in: ");
    var_dump($method->invoke(NULL));
    ?>

    The above example will output something similar to:

    ===> The user-defined final public static method 'increment' (which is a regular method) declared in /Users/philip/cvs/phpdoc/test.php lines 14 to 17 having the modifiers 261[final public static] ---> Documentation: '' ---> Invocation results in: int(1)
