How can PHP developers ensure that the format of the number retrieved from the database remains consistent when splitting it into separate strings?

When retrieving a number from the database in PHP, developers can ensure that the format remains consistent when splitting it into separate strings by using the number_format() function to format the number with a specific number of decimal places before splitting it. This ensures that the number will always have the same format regardless of the original value retrieved from the database. 

// Retrieve number from the database
$number = 123456.789;

// Format the number with 2 decimal places
$formattedNumber = number_format($number, 2, '.', '');

// Split the formatted number into separate strings
$parts = explode('.', $formattedNumber);

// Output the separate strings
echo $parts[0]; // Output: 123456
echo $parts[1]; // Output: 78
