  A          Z
  B          P
  B          Q
  C          R

I can able to show the results like above way.But now i wanna show results like below

Network Channel 
  A          x
             Y
             Z
  B          P
             Q
  C          R

Is there any way to show like above using loops

I’ll assume you have results in some kind of associative array from a database.

Here is a rough idea; store the network value in a “last_network” variable, and check to see when it changes. When it changes, print it, otherwise print only the channel.

echo "Network  Channel";
for ($i = 0; $i < $result_qty; $i++)
{
    $this_network = $results[$i]['network'];
    $this_channel = $results[$i]['channel'];

    if ($this_network != $last_network)
    {
        echo "$this_network      $this_channel";
        $last_network = $this_network;
    }
    else
    {
        echo "      $this_channel";
    }
}
