返回循环

Question

创建我是新来的PHP OOP所有的对象，我尝试使用OOP来选择，我有一个

class page { 
    var $title; 

    function settitle($title){ $this->title = $title;} 
} 

现在

class model { 

    connection $done ; 


    function getAllPages(){ 
     $query3 = "select * from pages"; 
     $result3 = mysqli_query($this->con,$query3); 
     while ($rows=mysqli_fetch_array($result3)){ 
      $page = new Page; 
      $page->setP_title($rows['p_title']); 
     } 
     return $page; 
    } 
} 

现在

class controller{ 
    function indexAllPage(){ 
     $pages = $this->conn->getAllPages(); 
     include('allpages.php'); 
    } 
} 

现在

查看 全部pages.php

Answer 1

，如果你想返回多个页面，您需要一个数组：

$pages = array(); 
while ($rows=mysqli_fetch_array($result3)){ 
    $page = new Page; 
    $page->settitle($rows['p_title']); 
    $pages[] = $page; 
} 
return $pages; 

UPDATE：

$pages = $this->conn->getAllPages(); 

// $pages is now an array, so you have to loop through it or get a specific index 

// get first page from array 
$page = $pages[0]; 

// loop through it 
foreach ($pages as $page) { 
    $title = $page->getTitle(); 
}
