Solution 2

Quote:
print_r("(".$temp.",".$y.")");
$temp = "";

the last line should be

$temp = " ";

That is, you missed a blank.

Take the space out of $temp,

You have $temp = " ";

Change to $temp = "";

and

if($temp !=="")

I gave you that code and it was working your not even trying man,

I also point out the reason that happened is cause in your if block your setting $temp to $temp = ""; See no space.
