PHP Textarea (for each)

Ok, im stuck and cannot figure this out.

I have a text area on my page and i will be putting a list of words in there one per line. When it posts it needs to put it in an arry so i can put each of those words in the database as a seperate result.

I can figure out how to put it in the database but here is my issue. If i type like this:



It then takes that space and stores it in the database. Is there anyway to strip out an Empty line so it doesnt effect my database query?

This is Kinda how i have it…


<?php $text = $_POST["text"]; $lines = explode("r",$text); $num = count($lines); for($i=0;$i<$num;$i++) { $var1 = $lines[$i]; $var = str_replace('r', '', $var1); echo $var; } ?>


Even in that code it keeps the extra line in the result. Any ideas?
