What is the best way to retrieve the highest value from a specific column in a database using PHP?

To retrieve the highest value from a specific column in a database using PHP, you can use a SQL query with the MAX() function to find the maximum value in that column. You can then fetch the result and use it as needed in your PHP code. 

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

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

// Query to retrieve the highest value from a specific column
$sql = "SELECT MAX(column_name) AS max_value FROM your_table";
$result = $connection->query($sql);

if ($result->num_rows > 0) {
    // Output the highest value
    $row = $result->fetch_assoc();
    echo "The highest value in the column is: " . $row['max_value'];
} else {
    echo "No results found";
}

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