Delete row if match is found with previous row

Content

Hi,

I have a report that brings back incidents and various bits of information. The Incident Reference number will be repeated but I've sorted it in a way where latest is first.

So if I have the first column something like

#101 | Resolved
#101 | Updated
#101 | New

The code below is what I thought would help. However when I run it, I still get the 3rd row showing. Any ideas?

Code Snippet

             global $curr_ref;

if ($rows[0][0]->val == $curr_ref)
{
unset($rows[0]);
}

$curr_ref = $rows[0][0]->val;
