How to round up a number to nearest 10?

floor() will go down.

ceil() will go up.

round() will go to nearest by default.

Divide by 10, do the ceil, then multiply by 10 to reduce the significant digits.

$number = ceil($input / 10) * 10;

Edit: I’ve been doing it this way for so long.. but TallGreenTree’s answer is cleaner.
