Here is my code :

<html> 
<head> 
 
  <style type="text/css"> 
    table { 
      border-collapse: collapse; 
      border: 1px solid black; 
    } 
    table td,th { 
      border: 1px solid black; 
    } 
    td { 
      text-align: center; 
    } 
  </style> 
</head> 
 
<body> 
 
  <h2>Play Lists</h2> 
 
  <table> 
    <th>Voice SKU</th> 
    <th>Voice Name</th> 
    <th>Action</th> 
 
 
    <?php 
    session_start(); 
   foreach ($_SESSION['playlist'] as $key => $value) { 
    echo "<tr>"; 
    echo "<td>" . $key . "</td>\n<td>" . $value . "</td>"; 
 
    echo "<td>". "<button id='btn'>Delete</button>"."</td>"; 
 
    echo "</tr>";   
    } 
    ?> 
  </table> 
</body> 
</html>

output:

You can pass the $key to delete to the script, like script.php?key=xxx

And to delete you do :


$key_to_delete=$_GET['key'];

if(isset($_SESSION['playlist'][$key_to_delete]))
{
 unset($_SESSION['playlist'][$key_to_delete]);
}

Make a pardon to ask more details, i am in the learning stage,

here is my code :

<html>
<head>

 <style type="text/css">
 table {
  border-collapse: collapse;
  border: 1px solid black;
 }
 table td,th {
  border: 1px solid black;
 }
 td {
  text-align: center;
 }
 </style>
</head>

<body>

 <h2>Play Lists</h2>

 <table>
 <th>Voice SKU</th>
 <th>Voice Name</th>
 

 <?php
 session_start();
 foreach ($_SESSION['playlist'] as $key => $value) {
 echo "<tr>";
 echo "<td>" . $key . "</td>\n<td>" . $value . "</td>";
 
 // $key_to_delete=$_GET['$key'];

 // if(isset($_SESSION['playlist'][$key_to_delete]))
 // {
 // unset($_SESSION['playlist'][$key_to_delete]);
 // }


 echo "<td>" ."<button class='delbtn' data-id='"+ k +"'>Delete</button>" . "<td>";


 echo "</tr>"; 
 }

 ?>
 </table>
</body>
</html>

How can i use your code? I know i am asking pure coding help, but i really don't know how to do?

 session_start(); 

 if(isset($_GET['key']))
 {
  $key=$_GET['key'];
  if(isset($_SESSION['playlist'][$key]))
  {
   unset($_SESSION['playlist'][$key]);
  }
 }

 foreach ($_SESSION['playlist'] as $key => $value)
 { 

  $url=$_SERVER['PHP_SELF'].'?key='.$key;
  echo "<tr>"; 
  echo "<td>" . $key . "</td>\n<td>" . $value . "</td>"; 
  echo "<td><a href=\"",$url,"\">Delete</a></td>"; 
  echo "</tr>"; 
 }

I just improvised the code here, so it might not work straight away.

If you want to use a button, you can use the onclick event.

Also in your code, you have the id="btn" which is incorrect, because each id has to be unique.

I never used PHP 's session system ,so I guess there is a feature to use, to save the modifications.
