Front-end editor is not required, only Insert formatted text to MYSQL.

In the future, formatted text will be displayed on the front-end.

------ Solution --------------------
First, I want to explain that the concept of segmentation does not exist in textarea;
Unless you use the UBB text editor;

Second, in textarea, only line breaks, other bold, font, size, color, labels, and so on will not have any effect;
Therefore, in textarea, only the line feed mode can be retained;

Php processes line breaks;
Stored in the database:
$ Content = str_replace ("
", Chr (10), $ content); // chr (10) line break ascii code

Input is edited in textarea;
$ Content = str_replace ("\ n ","
", $ Content );
