How can I load database records in a popup window using PHP?

To load database records in a popup window using PHP, you can create a separate PHP file that retrieves the records from the database and formats them for display. Then, use JavaScript to open a popup window and load the PHP file using AJAX to fetch the database records and display them in the popup window.

```php
// PHP code to fetch database records and format them for display

// Connect to the database
$connection = mysqli_connect("localhost", "username", "password", "database_name");

// Check connection
if (!$connection) {
    die("Connection failed: " . mysqli_connect_error());
}

// Query to fetch records from the database
$sql = "SELECT * FROM table_name";
$result = mysqli_query($connection, $sql);

// Format records for display
while($row = mysqli_fetch_assoc($result)) {
    // Display records in desired format
    echo "<p>" . $row['column_name'] . "</p>";
}

// Close database connection
mysqli_close($connection);
```

This PHP code snippet retrieves records from a database table and formats them for display. You can then use JavaScript to open a popup window and load this PHP file using AJAX to fetch the database records and display them in the popup window.
