Question

I am trying to take a text area value and run it through regular expression to split it to lines.

so if someone wrote a line then enter and another line and enter the i will have an array with each line per array value

The expression I’ve came up with so far is :

 (.+?)\n|\G(.*)

and this is how i use it(from a website i use to test expressions http://myregextester.com/)

 $sourcestring="
 this is a sentense yeaa
 interesting sentense
 yet another sentese
 ";
 preg_match_all('/(.+?)\n|\G(.*)/',$sourcestring,$matches);
 echo "<pre>".print_r($matches,true);

however there is 1 object in the array that always empty and i am trying to find a way to get rid of it.

Thanks in advanced.

You don’t need a regex for this, just use explode(), like so:

$lines = explode( "\n",  trim( $input));

Now each line of the user’s $input will be a single array entry in $lines.
