How can PHP developers ensure that the decimal formatting of numbers is consistent and accurate?

To ensure consistent and accurate decimal formatting of numbers in PHP, developers can use the number_format() function. This function allows developers to specify the number of decimal places, decimal point, and thousands separator for a given number, ensuring uniform formatting across different numbers. 

$number = 1234.56789;
$formatted_number = number_format($number, 2, '.', ',');
echo $formatted_number; // Output: 1,234.57
