Preserved Topic: preg_replace for "\n"?

I enter data via a form into a MySQL database (via PHP). One of the form fields is a textarea. I need to convert line breaks/carriage returns to "=0D=0A". An example would be

"Hello, this

is

my text"

would be converted to

"Hello, this=0D=0Ais=0D=0Amy text"

but I'm having a hard time. I've tried

$comments = preg_replace("\n", "=0D=0A", $comments);

but that get's me an "Empty regular expression" error. What's the best method, and should I replace the text BEFORE writing it to the database, or just when reading/displaying it? Eventually, I'm going to need to replace the "=0D=0A" with the line breaks when I present the data back to the user for editing. But that's later.....

PS - And it wasn't my call to use "=0D=0A" - it's part of the vCard standard ( http://www.ietf.org/rfc/rfc2426.txt )

preg_replace("/\n/m", "=0D=0A", $comments);

you are not adding the modifiers to your expression.

Pugzly, I suggest that you use str_replace() function insetad of preg_replace() for such simple search/replace operation (preg_replace() is really an overkill in this case)...

$comments = str_replace("\n", "=0D=0A", $comments);

Also, you should perform the replace before adding data to the database.

Ah....str_replace()

That worked great.

Thanks!
