每当我试图宣布一个等级时,就会出现这一错误:

Parse error: syntax error, unexpected T_VARIABLE, expecting T_OLD_FUNCTION or
T_FUNCTION or T_VAR or  }  in /home3/foundloc/public_html/booka/page2.php
on line 7 (line 7 is the class declaration by the way).

我在此试图宣布:

Class abc
{

$a = “Hello!”;

}

是否在需要转向的购买力平价上有一些条件? 我感到,如果电视在问题类型上挂牌,那是你检查的。

Answer 1

你们可以宣布这种类型的财产。某类人员可以是数据成员(客户和财产)或方法。在PHP 5型做事方式中,这基本上是它如何运作:

// de facto best practice: class names start with uppercase letter
class Abc
{
    // de facto best practice: ALL UPPERCASE letters for constants
    const SOME_COSTANT =  this value is immutable ; // accessible outside and inside this class like Abc::SOME_CONSTANT or inside this class like self::SOME_CONSTANT

    public $a =  Hello ; // a data member that is accessible to all
    protected $b =  Hi ; // a data membet that is accessible to this class, and classes that extend this class
    private $c =  Howdy ; // a data member that is accessible only to this class

    // visibility keywords apply here also
    public function aMethod( $with, $some, $parameters ) // a method
    {
        /* do something */
    }
}

确实,你不应考虑使用第4号站点的做法,即用<代码>var的关键词宣布数据成员,除非你仍在为第4号站点开发数据。

Answer 2

提出

class abc {
  public $a = "Hello!";
}

或

class abc {
  var $a = "Hello!";
}

Answer 3

审判

<?php
Class abc {
   var $a = "Hello!";
}
?>

应开展工作。您必须用var <>/em>或public<>/em>或 private加上static关键词来说明该成员的可见度。
