Subject: Re: [PHP] Still trying to figure this out...
Have you ever thought of doing something like this:
for($i = 0; $i <= $maxport; $i++)
{
$query="SELECT switchport FROM network WHERE switchport = ".$i;
$result=mysql_query($query);
if(empty($result))
{
echo "<p>$i</p>";
}
}
It should only return the ones that aren't in the table and they will
automatically be sorted in ascending order.

Ok, I am still trying to get this figured out from what I tried doing last
night. If anybody wants to try it, please be my guest. This is the deal. Create
an INTEGER table. Put the numbers 1 - 24 in it. Leave out like number 8, 9, 22,
23 ect.. Now create a php statement that will take and pull that out of the
database, find out the missing numbers and display them as an html drop down
selection.
And tedd in response to why, is because the values that are already located
in the database represent in use already. They represent a server port that a
server is sitting on, so that's not the problem. I could have done that along
time ago.
Any help is appreciated but here is the current code that I have.
$query="SELECT switchport FROM network";
$result=mysql_query($query);
$sql_range=mysql_fetch_array($result);
$true_range=range(1,24);
$next_range=array_diff($true_range,$sql_range);
foreach ($next_range as $final_range) {
echo "<option value='$final_range'>$final_range\n";
}
