[RESOLVED] Array Help

[thekidscareya]

I have 3 variables: $link_row & $id.

$link_row is an array of numbers and $id is a number

$link_row looks like this:
Array ( [0] => 1 [1] => 2 [2] => 3 [3] => 4 ) ...the values for the keys have different numbers at different times

$id will be a value for one of the keys in the array

I want to set the $prev variable to the value of the key before the key that corresponds with $id.

I also want to set the $next variable to the value of the key after the key that corresponds with $id.

Ex:
if $id = 2, then $prev = 1 and $next = 3.

I don't want to add/subtract with $id because the array can look like this:
Array ( [0] => 1 [1] => 2 [2] => 7 [3] => 24 )
I just want to get the value of the key before and after the key corresponding to $id.

How do I do this?

Thanks in advance for you help. I apprecaite it.

I figured this out after a long time...is there a quicker way to do this?

foreach($link_row AS $key=>$image_id)
	{
	if($image_id < $id)
		{
		$prev[] = $image_id;
		}
	if($image_id > $id)
		{
		$next[] = $image_id;
		}
	}

$next = $next[0];

if(is_array($prev))
	{
	$prev = end($prev);
	}
