Hey guy, I really need your help with this. I have Input from a text area, in this format: a b c d e f g 12 34 435 124 What I need do to is to output only a certain line from every block of text, every block is divided by one or more empty lines. I have done this: $input = $_POST["input"]; $lines = explode("\r",$input); $num = count($lines); $line_to_extract = $_POST['line_to_extract']; for($i=0;$i<$num;$i++) { if($i == $line_to_extract) { echo 'Line '.$i.': '.$lines[$i].'<br />'; } } What I need to do is to detect the empty line so I can keep track of the line to extract. PLEASE HELP!!!
