Question

我在profile.php中有这段代码：

$table_to_paginate  = 'updates';
$posts_per_page = 5;
require_once ("pagination/start_pagination.php");

$query  = "SELECT * FROM updates ";
$query .= " ORDER BY id DESC ";
$query .= " LIMIT {$start}, {$posts_per_page}";

在包含的文件中，即＆＃39; pagination / start_pagination.php＆＃39;我有这些代码：

//max displayed per page
            $per_page = $posts_per_page;
            //get start variable
            if(isset($_GET['start'])) {
            $start = $_GET['start'];
            }
            //count records
            if(!isset($additional_info)){$additional_info = NULL;}
            $counting = "SELECT * FROM {$table_to_paginate}";
            $counting .= "{$additional_info}";
            $record_count = mysql_num_rows(mysql_query($counting));
            //count max pages
            $max_pages = $record_count / $per_page; //may come out as decimal
            if (!isset($start)) {
                if(isset($upsidedown)){
                    if($record_count - $per_page < 0 ){ $start = 0;} else {$start = $record_count - $per_page;}
                } else {
                 $start = 0;
            }
            }

问题是，include可以找到该文件，但它不提供包含文件中的变量，以便我可以在profile.php中使用它。有趣的是，它适用于localhost，但是当我将它上传到服务器时，它不起作用。

其他信息：我需要包含文件的$ start。

如果要跨文件边界使用变量，则需要通过$GLOBALS数组访问变量：

// in profile.php
$query .= " LIMIT {$GLOBALS['start']}, {$posts_per_page}";

// in start_pagination.php
$per_page = $GLOBALS['posts_per_page'];
// ... snip
$counting = "SELECT * FROM {$GLOBALS['table_to_paginate']}";

包含文件中的代码在上传到服务器时不会执行
