Now does var_dump() get class function names?

class animal
{
  var $type;
  var $says;

  function __construct($_type)
  {
      $type = $_type;
  }

  function 开发者_JS百科Does_he_think_hes_the_boss()
  {
      return ($type == 'cat');
  }  
} // animal

$dog = new animal('dog');

var_dump($dog);

gives

object(animal)[1]
  public 'type' => null
  public 'says' => null

I'd like to get as much info as I can about a class (for debugging porpoises) - names of variables, names of functions (with their signatures, if possible), parent class, if any, etc ...

How much info can I get from an object?

You can retrieve all detailed information you need about object using reflection

You can look into debug_backtrace()

function dump( $var ) {
    $result = var_export( $var, true );
    $loc = whereCalled();
    return "\n<pre>Dump: $loc\n$result</pre>";
}

function whereCalled( $level = 1 ) {
    $trace = debug_backtrace();
    $file   = $trace[$level]['file'];
    $line   = $trace[$level]['line'];
    $object = $trace[$level]['object'];
    if (is_object($object)) { $object = get_class($object); }

    return "Where called: line $line of $object \n(in $file)";
}
