代码如下，因为构造函数中需要传入多个值，而每次传入的值个数可能不固定，如果没有传入，就使用构造甘薯中默认的值，所以这里我采用数组传入，在下面我已经通过implode将数组切成字符串并用","连接了，为什么传进去后 都转入了$host的变量下，结果是
host:192.168.1.1,1212
port:80
也就是说post传到了$host里而port还是用的类中默认的
class test{ public function __construct($host="127.0.0.1",$port="80") { echo 'host:'.$host."<br>"; echo 'port:'.$port; }}$data['host']='192.168.1.1';$data['port']='1212';$str=implode(',',$data);$obj=new test($str);host:192.168.1.1,1212port:80
低级错误
$str 就一个变量啊，程序怎么会自动理解为两个呢
这么传参等于是你传了一个host变量192.168.1.1,1212 port变量没传 还是使用类默认的80
要这样写
class test{ public function __construct($host="127.0.0.1",$port="80") { echo 'host:'.$host."<br>"; echo 'port:'.$port; } }$data['host']='192.168.1.1';$data['port']='1212';$ref = new ReflectionClass('test');$obj = $ref->newInstanceArgs($data);
<?phpclass test{ public static function new_object($data = array()) { switch(count($data)) { case 2: return new self($data['host'], $data['port']); case 1: return new self($data['host']); default: return new self(); } } public function __construct($host="127.0.0.1",$port="80") { echo 'host:'.$host."<br>"; echo 'port:'.$port; } } $data['host']='192.168.1.1';$data['port']='1212';//$str=implode(',',$data);//$obj=new test($str);$obj = test::new_object($data); $ref = new ReflectionClass('test');
$obj = $ref->newInstanceArgs($data);
