explode textarea php (at new lines)
提问by Chris Muench
can I do:
我可不可以做：
explode("\n", $_POST['thetextarea']);
and have it work on all platforms? (The question I am asking is will it ever be \r\n and not just \n")
并在所有平台上工作？（我要问的问题是它会不会是 \r\n 而不仅仅是 \n”）
EDIT:
编辑：
I forgot to mention that I am saving $_POST['thetextarea'] to a mysql database VARCHAR 255. It seems \r\n is converted to \n.
我忘了提到我正在将 $_POST['thetextarea'] 保存到 mysql 数据库 VARCHAR 255。似乎 \r\n 已转换为 \n。
