Well, the title says it all. First, I got the input from the textarea to a variable. Next, I want to split that string into an array, dividing it by each newline. Depending on the client's OS, newline can be \n, \r, or \r\n.

Here is what I tried:

$array = split('[\n,\r,\r\n]', $textarea_input);

I just started teaching myself php yesterday and I was wondering if this would work to print the array to the screen:

<?
for($x=0; $x<sizeof($array); $x++){
echo $array[$x];
?>
<br>
<? } ?>

$array = preg_split('/(\r?\n)+/', $textarea_input);

This is saying, 'split on one or more consecutive instances of "\r" or "\r\n",'

If what you told me is correct, my for loop is incorrect. I tried the code. I didn't get any errors, which is good, but nothing was printed to the screen.

This worked OK for me:
