this is untested but should get you going down the right road
and this is assuming that you add the value = (6*X + 1*Y)
you didn't say that, so I am just guessing.
<?php
$var = 4;
$x = 1;
$y = 2;
$value = 0;
if ( ($var % 2) == 0 ) {
$value = ($var * $x);
} else {
$value = ( ( ($var-1) * $x ) + $y );
}
echo $value;
?>
Give this a shot, it should give you the results that you are looking for.
But remember, this is untested, and just a guess as to the results you are
looking for.
