Rounding Numbers to the Nearest Ten in PHP

Rounding a number to the nearest ten is a common task in programming. In PHP, there are a few different methods to achieve this.

Using the round() Function:

The round() function rounds a number to the nearest integer. By default, it rounds to the nearest whole number, but you can specify a precision parameter to round to the nearest multiple of a specific value. To round a number to the nearest ten, you would use the following code:

<code class="php">$rounded_number = round($original_number, -1);</code>
Copy after login

For example, to round 23 to the nearest ten, you would use:

<code class="php">$rounded_number = round(23, -1); // 30</code>
Copy after login

Using the ceil() Function:

The ceil() function rounds a number up to the nearest integer. To round a number to the nearest ten, you would use the following code:

<code class="php">$rounded_number = ceil($original_number / 10) * 10;</code>
Copy after login

For example, to round 23 to the nearest ten, you would use:

<code class="php">$rounded_number = ceil(23 / 10) * 10; // 30</code>
Copy after login

This method is preferred by some developers because it is more efficient than using round().
