Question

它出错了，我想要它做的就是返回$ fcEnable作为这个类中数据库的结果.......

解析错误：语法错误，意外的T_VARIABLE /home/site/page.php

$VisitorIP = ip2long($_SERVER['REMOTE_ADDR']);
$IPCheckQ = mysql_query("SELECT * FROM `blah` WHERE `ip` = '" . $VisitorIP . "'");
$IPCheckR = mysql_fetch_array($IPCheckQ);
class GeoIP extends Page {
 public $fcEnable = $IPCheckR['x'];
}

Answer 1

您不能将另一个变量分配给类中的var。

class GeoIP extends Page 
{
 public $fcEnable;

 function __construct($fcEnable = null)
 {
        $this->fcEnable = $fcEnable
 }

}

Answer 2

$fcEnable属于GeoIP的范围。类的范围之外的代码需要在类中执行，或者像这样：

class GeoIP extends Page
{
    public $fcEnable;

    public function __construct( $ipcheck )
    {
         $this->fcEnable = $ipcheck['x'];
    }
}

$VisitorIP = ip2long($_SERVER['REMOTE_ADDR']);
$IPCheckQ = mysql_query("SELECT * FROM `blah` WHERE `ip` = '" . $VisitorIP . "'");
$IPCheckR = mysql_fetch_array($IPCheckQ);
$gip = new GeoIP( $IPCheckR );

PHP类无法正常工作
