How to put string in array, split by new line?

Is it possible when using the $_REQUEST[''] to only request one row from a text area?

Something like:

<?php 

  $text = $_REQUEST['originalText']; 

?>

<textarea name="firstRow" rows="5" cols="50" wrap="OFF" ><?php 
    echo $text
?></textarea>

<form action="index.php" method="POST" name="editText">
  <input name="submit" value="Edit Text" type="submit"><br>
  <textarea name="originalText" rows="5" cols="50" wrap="OFF"></textarea>
</form>

Instead of echo $text is it possible to echo just the first row of $text?

Answer 1

I don’t understand exactly what you mean by first row, but if you want to get the first line (before an “enter”) do the following:

list($first_line) = explode("\n", $text, 2);

Or alternatively (and preferably):

$first_line = strstr($text, "\n", true);

See strtr^Docs and Demo – you might want to add a "\n" to the $text to ensure at least one line exists.
