    Beispiel #1 ReflectionFunction::__construct() example

    <?php
    /**
    * A simple counter
    *
    * @return int
    */
    function counter1()
    {
    static     $c = 0;
    return ++    $c;
    }

    /**
    * Another simple counter
    *
    * @return int
    */
    $counter2 = function()
    {
    static     $d = 0;
    return ++    $d;

    };

    function     dumpReflectionFunction($func)
    {
    // Print out basic information
    printf(
    "\n\n===> The %s function '%s'\n".
    " declared in %s\n".
    " lines %d to %d\n",
    $func->isInternal() ? 'internal' : 'user-defined',
    $func->getName(),
    $func->getFileName(),
    $func->getStartLine(),
    $func->getEndline()
    );

    // Print documentation comment
    printf("---> Documentation:\n %s\n", var_export($func->getDocComment(), 1));

    // Print static variables if existant
    if ($statics = $func->getStaticVariables())
    {
    printf("---> Static variables: %s\n", var_export($statics, 1));
    }
    }

    // Create an instance of the ReflectionFunction class
    dumpReflectionFunction(new ReflectionFunction('counter1'));
    dumpReflectionFunction(new ReflectionFunction($counter2));
    ?>

    Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:

    ===> The user-defined function 'counter1'
     declared in Z:\reflectcounter.php
     lines 7 to 11
---> Documentation:
 '/**
 * A simple counter
 *
 * @return    int
 */'
---> Static variables: array (
  'c' => 0,
)


===> The user-defined function '{closure}'
     declared in Z:\reflectcounter.php
     lines 18 to 23
---> Documentation:
 '/**
 * Another simple counter
 *
 * @return    int
 */'
---> Static variables: array (
  'd' => 0,
)
