What is the correct syntax for retrieving the maximum value from a table using PHP and MySQL?

When retrieving the maximum value from a table using PHP and MySQL, you can use the SQL MAX() function in your query. This function allows you to find the maximum value of a specific column in a table. You can then fetch this value using PHP and display it as needed. 

<?php
// Connect to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

$conn = new mysqli($servername, $username, $password, $dbname);

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

// Query to retrieve the maximum value from a table
$sql = "SELECT MAX(column_name) AS max_value FROM table_name";
$result = $conn->query($sql);

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

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