How can you determine the largest number in a database column using PHP?

To determine the largest number in a database column using PHP, you can execute a SQL query to retrieve the maximum value in that column. This can be achieved by using the MAX() function in the SQL query along with the SELECT statement. Once the query is executed, you can fetch the result and display the largest number. 

// 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);
}

// SQL query to get the largest number in a column
$sql = "SELECT MAX(column_name) AS max_number FROM table_name";
$result = $conn->query($sql);

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

$conn->close();
