PHP --- reflection

• The so-called reflex is to define good after a class, class structure in order to gain information by reading the class name ReflectionClass process

class mycoach 
{ 
    protected $ name;
     protected $ Age;
     public function the __construct ($ name, $ Age) 
    { 
        $ the this -> name = $ name; 
        $ the this -> Age = $ Age; 
    } 
    public function EAT () 
    { 
        echo " ah , increased physical eat something " .PHP_EOL; 
    } 
}

• Get a reflecting object

$ coach = new mycoach ( 'Chenpei Chang', 22 is); 
$ A = the ReflectionClass new new ( 'mycoach'); 
IF ($ A-> isInstantiable ()) 
{ 
    echo "scientific training and diet" .PHP_EOL; 
}

$myattributes = $a->getConstructor();

var_dump($myattributes);

Output:

Scientific training and diet
 Object (ReflectionMethod) # . 3 ( 2 ) { 
  [ " name " ] =>
   String ( . 11 ) " the __construct " 
  [ " class " ] =>
   String ( . 7 ) " mycoach " 
}

 

• Method One getProperties () Note! To achieve print two attributes, be sure to declare two property protection in the class structure in (for example: protected $ name)

$property = $a->getProperties();
print('=================property================='.PHP_EOL);
var_dump($property);

Output:

=================property=================
array(2) {
  [0]=>
  object(ReflectionProperty)#4 (2) {
    ["name"]=>
    string(4) "name"
    ["class"]=>
    string(7) "mycoach"
  }
  [1]=>
  object(ReflectionProperty)#5 (2) {
    ["name"]=>
    string(3) "age"
    ["class"]=>
    string(7) "mycoach"
  }
}

• Method II getMethods () getname ()

print('=================methods================='.PHP_EOL);
var_dump($a->getMethods());
print('=================methods by row================='.PHP_EOL);

foreach($a->getMethods() as $method)
{
    echo $method->getName().PHP_EOL;
}

Output:

=================methods=================
array(2) {
  [0]=>
  object(ReflectionMethod)#6 (2) {
    ["name"]=>
    string(11) "__construct"
    ["class"]=>
    string(7) "mycoach"
  }
  [1]=>
  object(ReflectionMethod)#7 (2) {
    ["name"]=>
    string(3) "eat"
    ["class"]=>
    string(7) "mycoach"
  }
}
=================methods by row=================
__construct
eat

• hasMethod() getMethod()

print('=================execute================='.PHP_EOL);

if($a->hasMethod('eat'))
{
    $method= $a->getMethod('eat');
    print_r($method);
}

Output:

=================execute=================
ReflectionMethod Object
(
    [name] => eat
    [class] => mycoach
)
