Question

Using thinkphp3.2.3, the textarea has been manually entered and newlined, but after submission, the database does not have any newline tags. How to solve it?

Answer 1

Add <pre>

when the page is displayed

<pre>{$content}</pre>

As shown in the picture

Answer 2

nl2br($str);

Convert the newline character to <br> and then store it in the database

Answer 3

The space (r) and newline character (n) in the textarea do not display labels in the database. You can use them when displaying the page

<pre>{$content}</pre>

But if a line of content is too long, it will not automatically wrap. You can also convert the textarea's line wrapping to

when displaying.

str_replace("\n", "<br>", $content4);

In this way, the output content will have line breaks.
