Can you provide an example of how to round a number in PHP to a specific decimal place?

To round a number in PHP to a specific decimal place, you can use the round() function. This function takes two parameters: the number you want to round and the number of decimal places to round to. For example, to round the number 3.14159 to 2 decimal places, you would use round(3.14159, 2), which would return 3.14.

$number = 3.14159;
$roundedNumber = round($number, 2);
echo $roundedNumber; // Output: 3.14
