How can an admin panel be implemented to simplify the process of adding custom fields in PHP?

Adding custom fields in PHP can be simplified by creating an admin panel where users can easily input the field name, type, and other details. This panel can then dynamically generate the necessary database tables and forms to handle the custom fields. 

<?php
// Code for creating an admin panel to add custom fields in PHP

// Connect to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";
$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Create a form in the admin panel for adding custom fields
echo "<form method='post' action='add_custom_field.php'>";
echo "Field Name: <input type='text' name='field_name'><br>";
echo "Field Type: <input type='text' name='field_type'><br>";
echo "<input type='submit' value='Add Custom Field'>";
echo "</form>";

// PHP code to handle form submission and add custom field to the database
if($_SERVER["REQUEST_METHOD"] == "POST") {
    $field_name = $_POST['field_name'];
    $field_type = $_POST['field_type'];
    
    $sql = "ALTER TABLE table_name ADD $field_name $field_type";
    
    if ($conn->query($sql) === TRUE) {
        echo "Custom field added successfully";
    } else {
        echo "Error adding custom field: " . $conn->error;
    }
}

$conn->close();
?>
