php 类 构造方法
php 类的构造方法传递数组,取出来是NULL。为什么???

class Excel{
  var $re;
  function __construct($re){
  $this->exc=$re;
  }
  function get(){
  return $this->re;
  }

}
?>

============
require_once("./b.php");
$tem=array(1,4,7,8);

$t = new Excel($tem);

$ff=$t->get();

var_dump($ff);======================NULL
?>



------解决方案--------------------
class Excel{
var $re;
function __construct($re){
$this->exc=$re;
}
function get(){
return $this->re;
}
}
属性名都不对应,如何能得到正确结果?
------解决方案--------------------
构造函数内 你都没给 属性 re 赋值
$this->exc=$re;
改成
$this->re=$re;
------解决方案--------------------
属性名不一致,$this->re与$this->exc 
 它俩统一一下
LZ大意了
