Incrementing a value in an array

[Veltu]

Hi all,

 

I'm having trouble attempting to increment values in an array...

 

$current = 5;

$next = array(

                     pic1 => array('slide' => $current),

                     pic2 => array('slide' => $current),

                     pic3 => array('slide' => $current));

 

I basically want it to use the $current value and then within the array increment the value to get the next three values; 6,7,8.

 

Every attempt I keep getting 5,5,5 returned and I'm quite stuck. 

 

Would be great help if someone could point me in the right direction.

This is as dynamic as it could be but since you haven't really provided much info to understand what this is going to be used for and how.  This should work based on your example.

$next = array(
                     pic1 => array('slide' => ($current + 1)),
                     pic2 => array('slide' => ($current + 2)),
                     pic3 => array('slide' => ($current + 3)));

Then increment $current.

 

And those array keys should be in quotes

    $current = 5;
    $next = array(
                         'pic1' => array('slide' => ++$current),
                         'pic2' => array('slide' => ++$current),
                         'pic3' => array('slide' => ++$current));

Thanks guys. 

 

If you could just answer this. If I now attempt to decrement $current.

 

$prev = array(
                         'neg_pic1' => array('slide' => --$current),
                         'neg_pic2' => array('slide' => --$current),
                         'neg_pic3' => array('slide' => --$current));

 

 

It returns:

 

7,6,5 - This has thrown me off a bit.

 

How would I get it to negate off the $current value of 5 to return 4,3,2?

 

Thanks!

Reset $current to 5 before setting your array
