自定义类的 PHP 数组

Question

我正在尝试创建一个自定义类并拥有这些对象的数组，但我似乎无法让它工作。这是我的代码:

class NavigationItem
{


private $_filename;
private $_linkname;

public function __construct($filename, $linkname)
{
    parent::__construct();

    $this->_filename = $filename;
    $this->_linkname = $linkname;
}

public function getFilename()
{
    return $_filename;  
}

public function getLinkname()
{
    return $_linkname;  
}
}

$navInfo = array();

$size = array_push($navInfo, new NavigationItem("index.php","HOME"),
                                  new NavigationItem("about.php","ABOUT"),
                                  new NavigationItem("coaches.php","STAFF"),
                                  new NavigationItem("summer.php","SUMMER 2011"),
                                  new NavigationItem("fall.php","FALL 2011"),
                                  new NavigationItem("history.php","HISTORY"),
                                  new NavigationItem("contact.php","CONTACT"));

echo "<table>";
echo "<tr>";
echo "<td colspan=\"7\" height=\"125px\"><img src=\"images/banner_blue_skinny.jpg\" alt=\"\" /></td>";
echo "</tr>";
echo "<tr>";

for($i=0; $i<$size; $i++)
{
echo "<td class=\"linkCell\"><a class=\"navigation\" href=\"" . $navInfo[$i]->getFilename() . "\">" . $navInfo[$i]->getLinkname() . "</a></td>";
}

echo "</tr>";

echo "<tr>";
echo "<td colspan=\"7\" class=\"gapCell\"></td>";
echo "</tr>";

echo “”;
echo “”;

有任何想法吗？

$this 用于在类的方法内表示类的对象，应该用于访问属性和调用同一类的其他方法内的方法。

public function getFilename()
{
    return $this->_filename;  
}

从类的构造函数中删除父构造的调用，因为它不是从任何其他类继承的

//parent::__construct();
