如何分离搜索栏中的结果并将其组合在一起？

Question

I've created search bar which is to search author with journal title. The data is imported from CSV and it is stored in comma value for the author column. This is my database: MySQL database

When i search 'knowledge management' the result i get is this:

Search Bar result

How can i seperate the authors(='%$keyword%' or most likely as '%$keyword%') and grouped the titles?

This is what i have tried:

     <?php
          if(ISSET($_POST['search'])){
        $keyword = $_POST['keyword'];

     ?>

    <div>

     <h2> Result for <?php echo $keyword?></h2>

   <?php

    require 'conn.php';
    $query = mysqli_query($conn, "SELECT  author_name, GROUP_CONCAT(title)grouped_title , 
    count(*) cnt FROM `blog` 
    WHERE `author_name` LIKE '%$keyword%'  GROUP BY author_name ") 
    or die(mysqli_error());
    $result_count = mysqli_num_rows($query);
    echo '<br /><div class="right"><b><u>'.$result_count.'</u></b> results found</div>';
    while($fetch = mysqli_fetch_array($query))
    {

        
    ?>




   <hr style="border-top:4px dotted #ccc;"/>

   <div style="word-wrap:break-word;">

    <h4><?php echo $fetch['author_name']?></h4>     

    <a href="get_blog.php?author_name=<?php echo $fetch['author_name']?>"> 
   <p><?php echo $fetch['grouped_title']?></p></a>

    <hr style=""/>


    <?php


        }
     ?>
   </div>
    <?php
    }
  ?>`

There are many ways to separate the code, including: explode()

simple example:

$str = "Hello,world"; 
$rechange = (explode(",", $str)); echo
$rechange[0];
