PHP5.3.27类名和方法名一致问题

以下代码是今天偶尔的一个想法:

class test{
    public $Version='PHP Version 5.3.27';
    const BR='<br />';

    function test(){
        echo __FUNCTION__.  self::BR;
        echo __CLASS__.  self::BR;
        echo $this->Version.  self::BR;
    }
    
    function __construct(){
        echo __FUNCTION__.  self::BR;
        echo __CLASS__.  self::BR;
        echo $this->Version.  self::BR;

    }
}
$test=new test();

运行结果报错:
Strict standards: Redefining already defined constructor for class test in xxxx
把析构和方法换一下位置,运行结果是正常的.

class test{
    public $Version='PHP Version 5.3.27';
    const BR='<br />';
   
  function __construct(){
        echo __FUNCTION__.  self::BR;
        echo __CLASS__.  self::BR;
        echo $this->Version.  self::BR;

    }

    function test(){
        echo __FUNCTION__.  self::BR;
        echo __CLASS__.  self::BR;
        echo $this->Version.  self::BR;
    }
    
   
}
$test=new test();

在我的记忆里第一种写法好像是析构冲突,但不确定暂且记下.
