PHP Reflection function

Some of the most commonly used PHP reflection functions Get_class Get_class_methods

1. Get_class? Returns the class name of the object

String Get_class ([object $obj])

Returns the name of the class to which the object instance obj belongs. Returns FALSE if obj is not an object.

Note: Classes defined in the PHP extension library return the names of their original definitions. In PHP 4, Get_class () returns the lowercase form of a user-defined class name, but in PHP 5 the name of the class name is returned as if it were the class name in the extension library.

Note: Since PHP 5, obj is optional if called in the method of the object.

Example#1 using Get_class ()

class Foo {
function foo ()
{
Implements some logic
}

Function name ()
{
echo "My name is", Get_class ($this), "/n";
}
}

Create an Object
$bar = new Foo ();

External call
echo "Its name is", Get_class ($bar), "/n";

Internal call
$bar->name ();

?>

The example above will output:

Its name was Foo My name is foo

2.get_class_methods? Returns an array of the method names of the class

Description

Array get_class_methods (mixed $class _name)

Returns an array of the method names that are defined in the class specified by Class_name. If an error occurs, NULL is returned.

Example#1 Get_class_methods () example

class MyClass {
Constructor
function MyClass ()
{
return (true);
}

Method 1
function Myfunc1 ()
{
return (true);
}

Method 2
function Myfunc2 ()
{
return (true);
}
}

$class _methods = get_class_methods (' MyClass ');
Or
$class _methods = get_class_methods (new MyClass ());

foreach ($class _methods as $method _name) {
echo "$method _name/n";
}

?>

The example above will output:

3.

Get_class_vars? Returns an array that consists of the default properties of the class

Description

Array Get_class_vars (string $class _name)

Returns an associative array of the default public properties of the class, with elements of this array in the form of varname = = value.

Note: Before PHP 4.2.0, Get_class_vars () will not contain uninitialized class variables.

Example#1 Get_class_vars () example

class MyClass {

var $var 1; There is no default value for this variable ...
var $var 2 = "xyz";
var $var 3 = 100;
Private $var 4; PHP 5

Constructor
function MyClass () {
Change some properties
$this->var1 = "Foo";
$this->var2 = "Bar";
return true;
}

}

$my _class = new MyClass ();

$class _vars = Get_class_vars (Get_class ($my _class));

foreach ($class _vars as $name = + $value) {
echo "$name: $value/n";
}

?>

The example above will output:
