check if $i is multiple of 10

[Vivid Lust]

Hi all,

 

How can i check if $i, and integer, is a multiple of 10. E.g:

 

INPUT 10

OUTPUT true

 

INPUT 2000

OUTPUT true

 

INPUT 170

OUTPUT true

 

INPUT 295

OUTPUT false

 

Thanks all!

Use the modulus operator (%)

 

if (($i % 10) == 0) {
     echo "$i is a multiple of 10<br />";
}

 

Basically checks if $i / 10 has a remainder, if it does it is not a multiple of the number you are checking it against.

Use the modulus operator: http://php.net/language.operators.arithmetic

 

if ($i % 10 == 0) {
  echo "true";
}
