str_replace and <br> *resolved*

[mendhak]

on page1.php, I have a <textarea>. The user can put in anything there, even new line characters. I want to use the str_replace function to replace any occurences of new line characters with "<br>"

How can I do this? (I'm guessing that vbCrlf isn't the correct one)

I always do:

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

But I've seen other people throw in combinationes of "\r\n"

[mendhak]

Aha... \n. This seems so familiar

I understand the \n must be newline. What is \r though?

\r is a carriage return. There's also an nl2br() function:

string nl2br(string string)


Returns string with '<br />' inserted before all newlines.

Thanks man.

Yeah I think you have to take into account that Linux, Mac and Windows all handle newlines differently, so just doing a str_replace won't always get it right (or at least that's my understanding of it).

[phpman]

that is correct.

\r = carrioage return and will work in windows
\n = newline and most of the time won't work in windows
\t = tab (I believe)

that is why most people use both.

Wont work in Windows? I've never had a problem using newlines in Windows...

[phpman]

that is what I said.... most of the time it does, but that is why they add \r to it to make sure.

Is what you said.

[phpman]

actually it is for the headers where it messes up.

Actually, my sack is in the back, I thank you.
