if(isset($_POST['task']) && $_POST['task'] != '') {
$_SESSION&#91;'tasks']&#91;] = $_POST&#91;'task'];
}

if(isset($_GET['delete'])) {
unset($_SESSION&#91;'tasks']&#91;$_GET&#91;'delete']]);
}
?>

<form method="post">
  <input type="text" name="task" placeholder="Enter task" required>
  <input type="submit" value="Add Task">
</form>

<h3>To-Do List</h3>
<ul>
<?php
if(isset($_SESSION['tasks'])) {
foreach($_SESSION&#91;'tasks'] as $key =&gt; $task) {
    echo "&lt;li&gt;$task &lt;a href='?delete=$key'&gt;Delete&lt;/a&gt;&lt;/li&gt;";
}
}
?>

Explanation:

• Tasks are stored inside a session array.
• You can add new tasks and delete them.
• No database needed for this version.
