What are the best practices for centralizing database information and dynamically populating PHP pages with the necessary data?

To centralize database information and dynamically populate PHP pages with the necessary data, it is recommended to use a database connection file to establish a connection to the database and retrieve the required data. This file can be included in all PHP pages that require database information. Additionally, using SQL queries to fetch data from the database and storing it in variables before dynamically populating the PHP pages can help streamline the process. 

<?php
// Include database connection file
include 'db_connection.php';

// Fetch data from database
$sql = "SELECT * FROM table_name";
$result = mysqli_query($conn, $sql);

// Dynamically populate PHP page with data
if (mysqli_num_rows($result) > 0) {
    while ($row = mysqli_fetch_assoc($result)) {
        echo "<p>{$row['column_name']}</p>";
    }
} else {
    echo "No data found";
}

// Close database connection
mysqli_close($conn);
?>
