including a page with that contains functions trows undefined function error in php

Question

I have three pages: group_data.php, getters.php, and homepage.php the are all contained in two different directories;

home is in the root folder, while both group_data.php and getters.php are in the inc/modules/ sub-folder;

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

this is the code in my group_data.php page:

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; 

}

calling the getfollowedGroupPosts() function works on the getters.php page, but including the getters.php page in homepage.php trows a the error below;

Fatal error: Call to undefined function getComments() in C:\xampp\server\htdocs\bridgoo\inc\modules\getters.php on line 5

what could be the problem

How are your scripts included in your homepage ? include, require ? — Jean-Luc Aubert, Aug 21 '17 at 13:00
The problem is not in `group_data.php`, its in `getters.php` on line 5. — castis, Aug 21 '17 at 13:00
now, i just got a down vote, I couldn't have asked the question in a less obscured manner, i just couldn't figure out where the problem came from — Maxwell, Aug 21 '17 at 13:07
Every time you use [the `mysql_`](http://stackoverflow.com/questions/12859942/why-shouldnt-i-use-mysql-functions-in-php) database extension in new code **[this happens](https://media.giphy.com/media/kg9t6wEQKV7u8/giphy.gif)** it is deprecated and has been for years and is gone for ever in PHP7. If you are just learning PHP, spend your energies learning the `PDO` or `mysqli` database extensions and prepared statements.

If you use relative Paths, you always have to use the Path relative to the File in which the other Files are included.

For Example, you have these Files:

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

If you include x.php into y.php by

include('x.php');

and later you include

include('y.php');

into your main.php, main.php will look for x.php in the same Directory as main.php - it will throw an Error. If you just call y.php it will work. Because relative to y.php, x.php is in the same Directory.

I recommend you to use absolute Paths therefore, if possible.

ya, i think thats the problem, it just worked magically, i have been at this for day now, thanks — Maxwell, Aug 21 '17 at 13:11
