Using PHP to find Out if a Nummber is Odd or Even

This little bit of scripts was most useful in the coding of Waist Shaping Knitting Calculator . It evens out the number of knitting stitches so that both sides of the waist line get to be adjusted evenly.

The 'if' condition tests if variable '$Sts' is an odd number:

if( $Sts & 1 ){
$Sts = $Sts + 1;} //true when $Sts is odd, so add 1 to $Sts to make it even.

This bit of php will be useful for further development of the Knitting Calculator series.
