PHP---反射--继续剖析

• 首先定义一个类

<?php
Interface trainning
{
    public function exec();
}
class mma implements trainning
{
    public function exec()
    {
        return "我是徐晓冬～练MMA找我就对了，北京著名的疯子教练就是我！";
    }
}
class muay_thai implements trainning
{
    public function exec()
    {
        return "雅木萨，练泰拳找我就对了，走吧普及岛海滩走一道";
    }
}
class sd implements trainning
{
    public function exec()
    {
        return "卧操～还找他妈的隋炀帝吗？要不到樊荣那里去看看";
    }
}

class mycoach
{
    protected $name;
    protected $age;
    protected $expertise=array();
    public function __construct($name,$age,trainning $martial)
    {
        $this->name=$name;
        $this->age=$age;
        $this->type = $martial;
    }
    public function setskill(Array $skill)
    {
        $this->skill = $skill;
        var_dump($this->skill);
        return (Array) $this->skill;
    }
    public function curriculum()
    {
        echo $this->type->exec();
    }
}
$coach  = new ReflectionClass('mycoach');
if ($coach->isInstantiable())
{
    echo "可以实例化".PHP_EOL;
}

$myinit = $coach->getConstructor();

• 通过反射获取类的构造函数的入参（或者说依赖）

$dependencies=$myinit->getParameters();
var_dump($dependencies);

foreach($dependencies as $dp)
{
    if (is_null($dp->getclass()))
    {
        echo "只是个普通参数".PHP_EOL;
    }
    else{
        echo "类的名字".$dp->getClass()->name.PHP_EOL;
    }
}

输出结果：

array(3) {
  [0]=>
  object(ReflectionParameter)#3 (1) {
    ["name"]=>
    string(4) "name"
  }
  [1]=>
  object(ReflectionParameter)#4 (1) {
    ["name"]=>
    string(3) "age"
  }
  [2]=>
  object(ReflectionParameter)#5 (1) {
    ["name"]=>
    string(7) "martial"
  }
}

array(3) {
  [0]=>
  object(ReflectionParameter)#3 (1) {
    ["name"]=>
    string(4) "name"
  }
  [1]=>
  object(ReflectionParameter)#4 (1) {
    ["name"]=>
    string(3) "age"
  }
  [2]=>
  object(ReflectionParameter)#5 (1) {
    ["name"]=>
    string(7) "martial"
  }
}
只是个普通参数
只是个普通参数
类的名字trainning

• getName getFileName

var_dump("获取列的名字： ".$coach->getName());
var_dump("获取类文件的路径: ".$myinit->getFileName());

输出结果：

string() "获取列的名字： mycoach"
string() "获取类文件的路径: /home/cpc/PhpstormProjects/untitled/duwa.php"
