What are some beginner-friendly methods for implementing features like deleting and editing table rows in a PHP application without using a database?

When working on a PHP application without using a database, implementing features like deleting and editing table rows can be challenging. One beginner-friendly method is to use sessions to store the data temporarily. You can create an array to hold the table rows, and then manipulate this array based on user actions like deleting or editing rows.

<?php
session_start();

// Initialize table rows array if it doesn't exist in session
if (!isset($_SESSION['table_rows'])) {
    $_SESSION['table_rows'] = [];
}

// Add a new row to the table
if (isset($_POST['add_row'])) {
    $new_row = $_POST['new_row'];
    array_push($_SESSION['table_rows'], $new_row);
}

// Delete a row from the table
if (isset($_GET['delete_row'])) {
    $row_index = $_GET['delete_row'];
    unset($_SESSION['table_rows'][$row_index]);
}

// Display the table rows
echo '<table>';
foreach ($_SESSION['table_rows'] as $index => $row) {
    echo '<tr>';
    echo '<td>' . $row . '</td>';
    echo '<td><a href="?delete_row=' . $index . '">Delete</a></td>';
    echo '</tr>';
}
echo '</table>';
?>

<form method="post">
    <input type="text" name="new_row" placeholder="Enter new row">
    <input type="submit" name="add_row" value="Add Row">
</form>
