How can PHP be used to ensure consistent decimal formatting across different numbers?

When dealing with decimal numbers in PHP, it's important to ensure consistent formatting to maintain accuracy and readability. One way to achieve this is by using the number_format() function, which allows you to specify the number of decimal places and the thousands separator. By applying number_format() to all decimal numbers in your code, you can ensure that they are consistently formatted across different values.

$number1 = 1234.56789;
$number2 = 9876.54321;

$formatted_number1 = number_format($number1, 2); // Outputs: 1,234.57
$formatted_number2 = number_format($number2, 2); // Outputs: 9,876.54

echo $formatted_number1 . "<br>";
echo $formatted_number2;
