How can the output of a rounded number be influenced in PHP?
When rounding numbers in PHP, the output can be influenced by specifying the number of decimal places to round to. This can be achieved using the round() function in PHP, which allows you to specify the number of decimal places as the second argument. By controlling the precision of the rounding, you can ensure that the output of the rounded number meets your requirements.
// Round a number to 2 decimal places
$number = 10.56789;
$roundedNumber = round($number, 2);
echo $roundedNumber; // Output: 10.57
