That's because you're trying to multiple the string '1' by the string '$var' -
(the string dollar sign, vee, etc.), not the contents of $var as a string.
$var itself needs to be a string. If it's a numeric value, you should still get
automatic conversion to a string. But if not, you can also use:
echo bcmul('1', (string)$var, 99);
