[PHP] positive sign after calculations

[ckevin]

I have some variables in php and want to display the results with signs ( + or - )

E.g.

$c = $a + $b ;

echo $c ;

$c would be any numbers with a + or - sign. E.g. -6 or +7, however, how can I add the + sign when the result is positive?

Thanks!

 

[hohoho]

the easiest way is
if($c>0) $c = "+".$c;

negative numbers get a - automaticcaly, i think
