How can PHP developers effectively retrieve and display array data stored in a database?

To retrieve and display array data stored in a database using PHP, developers can use SQL queries to fetch the data from the database and then loop through the results to display them on the webpage. This can be done using functions like mysqli_query() and mysqli_fetch_array().

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

// Query to retrieve array data
$query = "SELECT * FROM table_name";
$result = mysqli_query($connection, $query);

// Loop through the results and display the data
while ($row = mysqli_fetch_array($result)) {
    echo $row['column_name'] . "<br>";
}

// Close the connection
mysqli_close($connection);
?>
