PHP 5构造函数_construct无法正常工作 [英] php 5 constructor _construct does not work

问题描述

我们有php 5.3.0，我想使用构造函数_construct. 但是以某种方式在构造类的实例时不会调用此构造函数. 另一方面，旧的构造函数(函数ClassName())也可以工作. 新版本(_construct)不能与php 5.3.0一起使用吗?

We have php 5.3.0 and I would like to use the constructor _construct. But somehow this constructor is not called when an instance of the class is made. And old constructor ( function ClassName() ) on the other hand works. Should not the new version (_construct) work with php 5.3.0 ?

另一件事，我想用参数构建一个构造函数. 但是父构造函数没有.如果我尝试构建此php，则会告诉我构造函数必须具有与父构造函数相同的结构.是这样吗?

Another thing I would like to build an constructor with arguments. But the parent constructor has none. If I try to build this php tells me the constructor has to have the same construct like the parent constructor. Is this so ?

示例:

abstract class Foo{

   function _construct(){
   }
}

class Bar extends Foo{

   function _construct($arg){
     parent::_construct();
   } 
}

感谢您的回复

推荐答案

__construct()(两个下划线)

第二个问题:修复__construct()中的下划线，看看是否仍然存在问题.

Second question: fix the underscores in __construct() and see if this is still a problem.
