[Resolved] How to acheive this?

[bike5]

I get a variable $total and $value[1-total] as input. The values will be sets of 3 numbers like $value[1] = 002; $value[2] = 012;...ect.

I need to loop through all the values ($total is total number of values) and delete any duplicate values. Then a new $total_new will be set to the number of values without any duplicates and resort $value from [1-total_new] with the non-duplicate values.

After this I will have a string that holds a number sequence like '001002073012294'.
I need to loop the $total_new with the new values and erase those values in the $string by multiples of 3(ex: extract 000 from 210000 would extract the first 3, but it must extract the last three which is the 2nt set of 3 numbers). I tried to do this with strtok but could not get it to work. Maybe convert the string into an array holding a set of 3 numbers each from the string and then if that value == $value[1-total], make it ''(emtpy) and put the array back into a string.

If anyone knows how to do this please let me know how, I have spents hours on hours trying all kinds of methods and cannot get it to work right. I know it might be asking a lot but I am stuck.

Thank you for your time.

I figured out how to do the top part which seems way to easy compared to the code I was producing.

for($x=1;$x<=$overlap;$x++)
	{
		$delete[$x] = $_POST['number'.$x];
	}
	$delete = array_unique($delete);//gets unquie values
	$delete = array_reverse($delete);//reset the index to start at 0, then1,2,3ect.
	$count = count($delete);//counts have many to delete

I am still working on the last part. I will post resolved if I can get it.

Congrats to myself I fiannly after about 10 full hours trying this got it.

if(isset($_POST['accept']))
{
$col_c = GCI('char_sponsor');
	if($_POST['overlap']>0)
	{
		for($x=1;$x<=$_POST['overlap'];$x++)
		{
			$delete[$x] = $_POST['number'.$x];
		}
		$delete = array_unique($delete);//gets unquie values
		$delete = array_reverse($delete);//reset the index to start at 0, then1,2,3ect.
		$count = count($delete);//counts have many to delete

	for($x=0;$x<(strlen($col_c['char_sponsor'])/3);$x++)
	{
		$spon[$x] = substr($col_c['char_sponsor'],$x*3,3);
	}

	for($i=0;$i<$count;$i++)
	{
		for($x=0;$x<count($spon);$x++)
		{
			if($delete[$i]==$spon[$x])
			{
				$spon[$x] = '';
			}
		}
	}
	$update_sponsor = implode('',$spon) . $_POST['sponsor'].$_POST['support'];
} else
{
	$update_sponsor = $col_c['char_sponsor'] . $_POST['sponsor'].$_POST['support'];
}	
echo $update_sponsor;
mysql_query("UPDATE NAME SET char_sponsor = '$update_sponsor'
			WHERE char_name ='$user' LIMIT 1") or die(mysql_error());

}

All thanks to the fact that I read a post that used array_unique() and from there everything else fell in place. 🙂
