How to insert a php function?

Question

MySQL

Hello! I have something like this

<?php
                
                            $result = mysql_query(" SELECT * FROM eb_notes ORDER BY `id` DESC");
                            while ($row = mysql_fetch_array ($result)) { ?>

                                    <div class="item_notes">
                                    <span class="description_notes"><?php echo $row ['description']; ?></span>
                                    <div class="desc_data_time">
                                    <span class="notes_dt"><?php echo $row ['date']; ?></span>
                                    <span class="notes_dt" ><?php echo $row ['time']; ?></span>
                                    </div>
                                    </div>
                                
                        <?php }?>

It's all in the index file, so you don't need to do this, and I understand that. How can this be written into a function?
Tried like this

<?php
                
                            function hello()
                            while ($row = mysql_fetch_array ($result)) { ?>

                                    <div class="item_notes">
                                    <span class="description_notes"><?php echo $row ['description']; ?></span>
                                    <div class="desc_data_time">
                                    <span class="notes_dt"><?php echo $row ['date']; ?></span>
                                    <span class="notes_dt" ><?php echo $row ['time']; ?></span>
                                    </div>
                                    </div>
                                
                        <?php }?>

function hello(){
    $result = mysql_query(" SELECT * FROM eb_notes ORDER BY `id` DESC");

}

But unfortunately writes an error in . It seems to me that the variable is not being transferred... How to do it?

Answer 1

Have you tried learning the language you want to write in first?
I'll even give you a link: php.net/manual/ru/language.functions.php
After 5 minutes of reading enlightenment will come, try starting with this next time
