Question

unable to get my else if statement to work, does anyone have any ideas? it works without the else if….

$waveFeet = round("$ar2");
        if ($waveFeet >= 2) {
            echo $waveFeet - 1;
        }
        else if ($waveFeet > 5) {
            echo $waveFeet - 2;
        }

        else 
        {
            echo "$wavefeet";   
        }

also as a side question, can anyone tell me how to change my round() to make it always round (down) instead of rounding up or down…?

Answer 1

you can use floor for down round

$waveFeet = floor($ar2);                

if ($waveFeet > 5)
    echo $waveFeet - 2;
else if ($waveFeet >= 2) 
    echo $waveFeet - 1;
else 
    echo $wavefeet;   

you have to first check for 5 bcz 5 is big no than 2 and your first condition >= 2 also satisfied if no >5 so control go to first condition rather than second….
