Php solution:

Use the php function and str_replace to replace the function, such as str_replace ('N ','
'), The problem is that the replacement was not successful and never been replaced. after a long time, I began to doubt whether the linefeed in textarea was n. now I think it is too shaken, in fact, after I replaced n/n respectively, I intuitively told myself that I had entered a dead end. this is not a solution to the problem. there must be a fundamental error. Suddenly I thought about whether it would be a single quotation mark or double quotation mark, so the str_replace ('N ','
') Changed to str_replace ("n ","
"), The light flashed, and the replacement was successful.

Sequence description:

N: line feed (lf or ascii characters 0 × 0a (10 ))

R: Press enter (cr or ascii character 0 × 0d (13 ))

T: horizontal tab (ht or ascii character 0 × 09 (9 ))

/: Backslash

$: Dollar sign

": Double quotation marks
