データベースはMysqlを使っていますがPHPの実行結果をhtmlファイルとして書き出したいのですが echo "<li class='active'><a href='special.php?page={$i}'>{$i}</a></li>";のspecial.php?page={$i}'>{$i}ができません！！
例えば：{$i}が12の場合：special.php?page={$i}'>{$i}をspecial.html/12.htmlのようにしたいです！！誰かご教授くださいませ！！

下記はテスト環境から本番環境にphpファイルを自動的にHTMLファイルに書き出すプログラムです：
syc.php

$url = "http://test.local/index.php";
$buff = file_get_contents($url);
$fname ="http://product/test.html";

$fhandle = fopen($fname, "w");
fwrite($fhandle, $buff);
fclose($fhandle);
?>

下記はテスト環境でのindex.phpファイルです：

<?php require_once("includes/header.php"); ?>
<?php require_once("includes/db.php"); ?>
<?php  require_once("includes/navigation.php"); ?>
<div id="main" role="main">
    <section class="slider">
        <ul class="slides">
            <li data-thumb="/slider/images"><a href="/"><img src="images" /></a></li></ul>
    </section>
</div>
       <ul>
<?php
    $query = "SELECT * FROM test  ORDER BY test_id DESC";
    $query = mysqli_query($db, $query);
        while($row = mysqli_fetch_assoc($query)){
            $test_id = $row['test_id'];
            $test_title = $row['test_title'];
            $test_image = $row['test_image'];
?>    
    <li><a href="#"><img src="./images/<?php echo $test_image; ?>" alt="</a><a href="#"><?php echo $test_title;?></li> 
    <?php } ?>
    </ul>

下記はincludes/navigation.phpファイルです：

<?php
   ob_start();
?>

    <div class="container">
        <div class="navbar-header">
            <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1">

                <?php echo "<li><a　href='http://test.local/camera/index.php'>カメラ</a></li>"; ?>
                <?php echo "<li><a href='http://test.local/iphone/'>携帯</a></li>"; ?>
            </ul>
      </div>
    </div>
</div>

下記はcameraカテゴリ-の一覧を表示するindex.phpファイルです：

    }
    if($page == "" || $page == 1){
        $page_1 = 0;
    }else{
        $page_1 = ($page * $per_page) - $per_page;
    }
    $count = "SELECT * FROM camera";
    $find_count = mysqli_query($db, $count);
    $count = mysqli_num_rows($find_count);
    $count = ceil($count / $per_page);
    $query = "SELECT * FROM camera ORDER BY camera_id DESC LIMIT $page_1, $per_page";
    $camera_query = mysqli_query($db, $query);
    while($row = mysqli_fetch_assoc($camera_query)){
