Good afternoon. Well I don’t know if there’s a specific function for that, but you can do it this way using the ceil, and a simple mathematical logic.

Example:

$num = 142;
$arredondado = (ceil($num/10))*10;

//resultado 150;
    echo $arredondado;

Simply divide the number by 10, and round it up to catch the next number, then just multiply it by 10 and you have the desired number.

Like I said, I don’t know if it has a specific function, but it works.

I hope it helps.

  • Thanks! Taken care of!

  • Please put as an answer if you have solved your problem. Thank you

  • Could remove unnecessary quotes, since it is a function $arredondado = ceil($num/10)*10;

Basically this:

round( $a + 4, -1 );

Applied to your code:

$a = 142;
echo round( $a + 4, -1 );

See working on IDEONE.

Round serves for rounding of numbers in n decimal places, but if you use negative numbers, you refer to the tens, hundreds etc.

The -1 is 10 in 10, -2 of 100 in 100, and so on.

The +4 serves to always round up (PHP has a constant to choose this behavior in decimals, but it doesn’t work right for dozens) - note that this only makes sense for integers. If it’s for use with decimals, the best solution from @Fleuquer
