What are some alternative methods for retrieving a single value from a MySQL database in PHP other than the mysqli_field_query function mentioned in the thread?

One alternative method for retrieving a single value from a MySQL database in PHP is to use the mysqli_fetch_assoc function in combination with a SELECT query. This function fetches a row from a result set as an associative array, allowing you to access the desired value directly. Another method is to use the mysqli_fetch_array function, which fetches a row from a result set as an array, giving you access to the value by its index.

// Connect to MySQL database
$connection = mysqli_connect("localhost", "username", "password", "database");

// Execute SELECT query
$query = "SELECT column_name FROM table_name WHERE condition";
$result = mysqli_query($connection, $query);

// Fetch the result as an associative array
$row = mysqli_fetch_assoc($result);

// Access the value by its key
$value = $row['column_name'];

// Print the retrieved value
echo $value;

// Close the connection
mysqli_close($connection);
