Note Submitter: dr dot miljenko at gmail dot com ---- I have a textarea that has height 30px and width 150px When i wrote i continuous sentence, i fits fine as it should. Since the sentence is a string that does not know for new line, i cant use php to paste that text directly to image and watermark it... So the question is. How to detect in textarea where a new line starts? And explode that string to n strings, depends on number of lines.
