(PHP 5, PHP 7, PHP 8)
ReflectionClass::getMethod — 获取一个类方法的 ReflectionMethod。
name要反射的方法名称。
一个 ReflectionMethod。
如果方法不存在则会抛出 ReflectionException 异常。
Example #1 ReflectionClass::getMethod() 的基本用法
<?php
$class = new ReflectionClass('ReflectionClass');
$method = $class->getMethod('getMethod');
var_dump($method);
?>
以上例程会输出：
object(ReflectionMethod)#2 (2) {
["name"]=>
string(9) "getMethod"
["class"]=>
string(15) "ReflectionClass"
}
if you ever need to get the body of a method, use this extension (https://github.com/sagittaracc/reflection):
namespace sagittaracc\classes;
class Test
{
public function method()
{
if (true) {
return 'this method';
}
return 'never goes here';
}
}
$reflection = new ReflectionClass(Test::class);
$method = $reflection->getMethod('method');
echo $method->body; // if (true) { return 'this method'; } return 'never goes here';
If you ever need to get the type hint of a parameter in a method use this.
<?php
//Target our class
$reflector = new ReflectionClass('MyClass');
//Get the parameters of a method
$parameters = $reflector->getMethod('FireCannon')->getParameters();
//Loop through each parameter and get the type
foreach($parameters as $param)
{
//Before you call getClass() that class must be defined!
echo $param->getClass()->name;
}
?>
