nl2br small problem

[robert_gsfame]

I got this question in my mind.....when should we use nl2br?

is it used during inserting the data??

 

like $data=nl2br($_POST['text']);

So then i will have all html code stored inside the database like <br><br>

 

but what if let say i type "my name is <br> John" in the textbox

 

will this <br>changed into newline when retrieving the data from database??

Yes it would become a linebreak literally.

 

Unless you escape it (with htmlentities) or strip it etc.

The nl2br() function should only be used when displaying text that might contain the newline character on the screen. The newline character is NOT the html tag "<br \>", but the character(s) represented by "\n", "\r", or "\r\n" depending on the OS your script runs on.

 

The function doesn't replace the newline with "<br \>" but adds the "<br \> before the newline in the string.

No it wouldn't. it would be untouched.

 

Anyway, to the op. Its generally best practice to store your data in the format it was received in (once being validated of course). You can then format the output in a choice of different ways depending on the application.

if i use htmlentities then i will get another problem as all newline <br/> that user has from ENTER button also shown as <br/> not newline

 

So then i cannot prevent this happen?

[robert_gsfame]

okay i got the answer now...when display the record then i have to combine nl2br(htmlentities())

 

so that whatever html tag will be shown

 

thx!

Mind to explain?

 

<?php
echo nl2br("Bob <br /> Bob2 <br />");
?>

// Source 
Bob <br /> Bob2 <br />

A <br /> tag is NOT a line break.
