Rounding Up a Number to the Nearest 10 in PHP

Rounding off a number to the nearest 10 is a common task in programming. PHP provides several built-in functions for rounding numbers, including floor(), ceil(), and round().

To round a number to the nearest 10, we can use the ceil() function. ceil() rounds a number up to the nearest integer. By dividing the number by 10, applying ceil(), and then multiplying the result back by 10, we can effectively round the number up to the nearest ten.

Here's how we can round 23 to the nearest 10 in PHP:

<code class="php">$number = 23;
$roundedNumber = ceil($number / 10) * 10;
echo $roundedNumber; // Output: 30</code>
Copy after login

In this example, we divide 23 by 10 to get 2.3. We then apply ceil() to round 2.3 up to the nearest integer, which is 3. Finally, we multiply 3 by 10 to get the rounded number, which is 30.
