How can I ensure consistency in displaying decimal numbers in PHP?

When displaying decimal numbers in PHP, it is important to ensure consistency in formatting to avoid confusion or errors. One way to achieve this is by using the number_format() function in PHP, which allows you to specify the number of decimal places to display. By using this function consistently throughout your code, you can ensure that all decimal numbers are displayed in a uniform and readable manner.

// Example code snippet to ensure consistency in displaying decimal numbers
$number = 123.456789;
$formatted_number = number_format($number, 2); // Displaying 2 decimal places
echo $formatted_number;
