decrease count

hi,

i need help how to decrease by 1 in Number for example 100 - 1 = 99

my code in php:

PHP Code:

---

$credits=count($credits)-1; 


---

is this correct? assuming $credits got 100 then -1 so 99 and so on...

regards,

thanks...

solve it my problem :D

Count returns the number of elements in an array. Normal arithmetic will help you here:

Code:

---

$credits = $credits -1;

//shorter way
$credits -= 1;

one question, if the credits is 0 its totally zero? since my code is still counting till -1,-2,-3,-4 i want to set the credits if 0 then 0

regards,

You need to use an if statement.
