How can I display a zero after the decimal point in PHP?

When displaying a number in PHP, if the number has no decimal part, PHP will not automatically display a zero after the decimal point. To ensure that a zero is displayed after the decimal point, you can use the number_format() function in PHP. This function allows you to specify the number of decimal places to display, as well as the character to use as the decimal point and the thousands separator. 

$number = 10; // Number to display
$decimal_places = 1; // Number of decimal places
echo number_format($number, $decimal_places, '.', ''); // Output: 10.0
