使用PHP類生成網頁

我是一位正在嘗試使用OOP和PHP的大學生。我想使用BuildPage類建立一個頁面。使用PHP類生成網頁

<?php 
Class BuildPage { 
    private $title; 
    private $style; 
    private $head; 
    private $header; 
    private $page; 
    private $footer; 
    private $finalPage; 

    public function __construct($title, $style) 
    { 
    $this->title = $title; 
    $this->style = $style; 
    } 

    public function addHead() 
    { 
    $this->head = " 
    <!DOCTYPE html> 
    <html lang='en'> 
    <head> 
    <meta charset='utf-8'> 
    <title>$this->title</title> 
    <link href='$this->style' rel='stylesheet' type='text/css'> 
    <link rel='stylesheet' href='style.css'> 

    </head>"; 

    } 

    public function addToPage($partOfPage) 
    { 
    if(empty($this->page) || !isset($this->page)) 
    { 
    $this->page = $partOfPage; 
    } 
    else { 
    $this->page .= "<br> " . $partOfPage; 
    } 
    } 

    public function addHeader($header) 
    { 
    $this->header = "<body><div class='container'><header> " . $header . " 
    </header>"; 
    } 

    public function addFooter($footer) 
    { 
    $this->footer .= "<BR><footer> " . $footer . " </footer></div></body> 
    </html>"; 
    } 

    public function getPage() 
    { 
    $this->finalPage = $this->head . $this->header . $this->page . 
    $this->footer; 
    return $this->finalPage; 
    } 
} 

?>

然而，當我嘗試使用功能來構建頁面，我不明白如何在參數中使用PHP如下：

$buildPage->addToPage(" 
<!-- Here is our page's main content --> 
    <!-- Use function to display songs --> 

<?php $music->displaySongs('xmlfiles/songs.xml'); ?> 

");

如果我逃避$如\ $嘗試並使其成爲一個字符串，出於某種原因，它成爲HTML中的評論。這種方法有可能工作嗎？

非常感謝

編輯：

這是下面的索引頁，我調用類的帶有回聲底部。

<?php 
require_once('phpclasses/Connect.php'); 
require_once('phpclasses/BuildPage.php'); 
require_once('phpclasses/MusicIE.php'); 

$dbconnect = new Connect(); 
$music = new MusicIE(); 
$buildPage = new BuildPage("Music Website", "style.css"); 


$buildPage->addHead(); 
$buildPage->addHeader(" 
<!-- Here is the main header that is used accross all the pages of my 
website 
--> 
<div class='PageHeading'>Available Music Listed Below:</div> 
<nav> 
    <ul> 
    <li><a href='#'>Home</a></li> 
    <li><a href='#'>Register</a></li> 
    <li><a href='#'>Login</a></li> 
    </ul> 
</nav> 
<form> 
<input type='search' name='q' placeholder='Search query'> 
<input type='submit' value='Go!'> 
</form> 
"); 
$buildPage->addToPage(" 
<!-- Here is our page's main content --> 
    <!-- Use function to display songs --> 

" . $music->displaySongs('xmlfiles/songs.xml')); 

$buildPage->addFooter(" 
<!-- And here is my footer that is used across all the pages of our website 
--> 
    <p>©Copyright 2017 by Kris Wilson. All rights reversed.</p> 
"); 

echo $buildPage->getPage();

既然你傳遞一個字符串函數BuildPage::addToPage($partOfPage)你可以嘗試，而不是通過字面函數調用以字符串形式的$music->displaySongs('xmlfiles/songs.xml')結果。像這樣：

$buildPage->addToPage(" 
<!-- Here is our page's main content --> 
    <!-- Use function to display songs --> 

". $music->displaySongs('xmlfiles/songs.xml'));

我編輯了我原來的問題，如果我按照你的建議去做，它會在頁面頂部顯示HTML以外的結果 – Sifer

alter $ music-> displaySongs（'xmlfiles/songs.xml'））不會回顯字符串，而是返回它 –

看來你的代碼是錯誤的addToPage函數調用。你應該這樣稱呼它：

$buildPage->addToPage(" 
<!-- Here is our page's main content --> 
    <!-- Use function to display songs --> 

".$music->displaySongs('xmlfiles/songs.xml'));

您應該$music->displaySongs('xmlfiles/songs.xml')輸出添加到字符串的結尾。
