PHP - print all properties of an object

<?php var_dump(obj) ?>

or

<?php print_r(obj) ?>

These are the same things you use for arrays too.

These will show protected and private properties of objects with PHP 5. Static class members will not be shown according to the manual.

If you want to know the member methods you can use get_class_methods():

$class_methods = get_class_methods('myclass');
// or
$class_methods = get_class_methods(new myclass());
foreach ($class_methods as $method_name) 
{
    echo "$method_name<br/>";
}

As no one has not provided an OO approach yet here is like it would be done.

class Person {
    public $name = 'Alex Super Tramp';

    public $age = 100;

    private $property = 'property';
}


$r = new ReflectionClass(new Person);
print_r($r->getProperties());

//Outputs
Array
(
    [0] => ReflectionProperty Object
        (
            [name] => name
            [class] => Person
        )

    [1] => ReflectionProperty Object
        (
            [name] => age
            [class] => Person
        )

    [2] => ReflectionProperty Object
        (
            [name] => property
            [class] => Person
        )

)

The advantage when using reflection is that you can filter by visibility of property, like this:

print_r($r->getProperties(ReflectionProperty::IS_PRIVATE));

Since Person::$property is private it's returned when filtering by IS_PRIVATE:

//Outputs
Array
(
    [0] => ReflectionProperty Object
        (
            [name] => property
            [class] => Person
        )

)
