How can I ensure that my PHP code displays numbers with the correct decimal format?

When displaying numbers in PHP, it is important to ensure that they are formatted correctly, especially when dealing with decimal numbers. To display numbers with the correct decimal format, you can use the number_format() function in PHP. This function allows you to specify the number of decimal places to display and also set the thousands separator if needed. 

$number = 1234.56789;
$formatted_number = number_format($number, 2); // Displays the number with 2 decimal places
echo $formatted_number; // Output: 1,234.57
