• 所謂反射就是定義好一個類之后，通過ReflectionClass讀取類的名字從而獲取類結構信息的過程

class mycoach {protected $name;protected $age;public function __construct($name,$age){$this->name = $name;$this->age = $age;}public function eat(){echo "嗯，吃點增加體能的東西".PHP_EOL;} }

• 拿到一個反射對象

$coach = new mycoach('陳培昌',22);
$a = new ReflectionClass('mycoach');
if($a->isInstantiable())
{
echo "科學的飲食和訓練".PHP_EOL;
}
$myattributes = $a->getConstructor(); var_dump($myattributes);

輸出結果：

科學的飲食和訓練 object(ReflectionMethod)#3 (2) {["name"]=>string(11) "__construct"["class"]=>string(7) "mycoach" }

?

• 方法一??getProperties() 注意！要想實現兩個屬性的打印，務必在類結構體中聲明兩個保護屬性 (例如:protected $name)

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

輸出結果：

=================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"} }

• 方法二 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; }

輸出結果:

=================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); }

輸出結果：

=================execute================= ReflectionMethod Object ([name] => eat[class] => mycoach )Process finished with exit code 0

• 復制粘貼---快速測試

<?php class mycoach {protected $name;protected $age;public function __construct($name,$age){$this->name = $name;$this->age = $age;}public function eat(){echo "嗯，吃點增加體能的東西".PHP_EOL;} } $coach = new mycoach('陳培昌',22); $a = new ReflectionClass('mycoach'); if($a->isInstantiable()) {echo "科學的飲食和訓練".PHP_EOL; } $myattributes = $a->getConstructor(); var_dump($myattributes); $property = $a->getProperties(); print('=================property================='.PHP_EOL); var_dump($property); print('=================methods================='.PHP_EOL); var_dump($a->getMethods()); print('=================methods by row================='.PHP_EOL);foreach($a->getMethods() as $method) {echo $method->getName().PHP_EOL; } print('=================execute================='.PHP_EOL);if($a->hasMethod('eat')) {$method= $a->getMethod('eat');print_r($method); }
