How can PHP developers effectively handle data retrieval from a database and display multiple records using a template system?

PHP developers can effectively handle data retrieval from a database and display multiple records using a template system by first querying the database to fetch the desired records. Then, they can iterate over the results and populate a template with the data to display each record. Finally, the populated template can be rendered to show all the retrieved records.

<?php
// Connect to the database
$connection = new mysqli('localhost', 'username', 'password', 'database');

// Query the database to retrieve multiple records
$query = "SELECT * FROM records";
$result = $connection->query($query);

// Check if there are records to display
if ($result->num_rows > 0) {
    // Loop through each record and populate the template
    while ($row = $result->fetch_assoc()) {
        // Populate the template with the record data
        $template = "<div>{$row['column1']} - {$row['column2']}</div>";
        // Display the populated template
        echo $template;
    }
} else {
    echo "No records found.";
}

// Close the database connection
$connection->close();
?>
