After my test form textarea line break, it is rn under windows and n under linux (this is not true

test), in addition, under win, r and n both have line-breaking functions

Table 6-1. Escape characters

Sequence
Meaning

n
newline (lf or ascii character 0×0a (10))

r
carriage return (cr or ascii character 0×0d (13))

t
Horizontal tab character (ht or ascii character 0×09 (9))

Backslash

$
Dollar sign

”
Double quotes

[0-7]{1,3}
This regular expression sequence matches a character represented in octal notation

x[0-9a-fa-f]{1,2}

Summary: Many friends say that the newline code n in textarea is like this str_replace("n","

/>”), but we don’t know that this is not the standard line break of window. We should change it to str_replace

("nr","
")This is KO.
