Question

我有三个页面：group_data.php，getters.php和homepage.php 这些都包含在两个不同的目录中;

home位于根文件夹中，而group_data.php和getters.php都位于inc/modules/子文件夹中;

inc/modules/group_data.php，inc/modules/getters.php

这是我的group_data.php页面中的代码：

function getComments($post_id){

    $sql_query = mysql_query("SELECT * FROM replies WHERE pid = '$post_id'");

    $row_count = mysql_num_rows($sql_query);
    while($rows = mysql_fetch_assoc($sql_query)) {

        $record_set[] = array('comment_count' => $row_count,
                    'pid' => $rows['pid'],
                    'date' => timeAgo($rows['date']),
                    'comment' => $rows['comment']   
                );
    }
    return $record_set;
}

function getFollowedGroupPosts($user_id){

    $sql_query = mysql_query("SELECT gid FROM members WHERE uid = '$user_id'");

    $row_count = mysql_num_rows($sql_query);
    while( $rows = mysql_fetch_assoc($sql_query)) {
        $tag = $rows['gid'];
        $pushed_array = array_fill(0, $row_count, $tag );

        $ids = join("','",$pushed_array);   
        $sql_bound = mysql_query("SELECT * FROM posts WHERE gid IN ('$ids')");
        $row_count_b = mysql_num_rows($sql_bound);
        while( $rows_b = mysql_fetch_assoc($sql_bound)) {

            //get images url as comma seperated strings
            $url_string = json_encode(getPostImages($rows_b['pid']));

            $record_set[] = array('gid' => $rows_b['gid'],
                    'pid' => $rows_b['pid'],
                    'post' => $rows_b['post'],
                    'images' => getPostImages($rows_b['pid']),
                    'jImages' => $url_string,
                    'videos' => getPostVideos($rows_b['pid']),      
                    'audios' => getPostAudios($rows_b['pid']),
                    'date' => timeAgo($rows_b['date']),
                    'username' => userIdToName($rows_b['uid']),
                    'filemap_id' => $rows_b['filemap_id'],
                    'group_name' => groupIdToName($rows_b['gid']),
                    'comments' => getComments($rows_b['pid']),
                    'likes' => checkLikeCount($rows_b['pid']),
                    'post_count' => $row_count_b);
        }

    }
    return $record_set; 

}

调用getfollowedGroupPosts()函数可以在getters.php页面上运行，但是在homepage.php中包含getters.php页面会产生以下错误;

致命错误：在第5行的C：\ xampp \ server \ htdocs \ bridgoo \ inc \ modules \ getters.php中调用未定义的函数getComments（）

可能是什么问题

Answer 1

如果使用相对路径，则始终必须使用相对于包含其他文件的文件的路径。

例如，您有以下文件：

main.php
include/x.php
include/y.php

如果您通过

将x.php包含到y.php中

include('x.php');

以后再加上

include('y.php');

进入你的main.php，main.php会在与main.php相同的目录中查找x.php - 它会抛出一个错误。如果你只是打电话给y.php就行了。因为相对于y.php，x.php位于同一目录中。

我建议你尽可能使用绝对路径。

包括一个包含函数的页面在PHP中拖出未定义的函数错误
