processing multi line form object

Anon

hi,

Im using multiline forms to get visitor essays, but when record data to mysql

I write to form:

hi,
there

to have this output Ihave to write
hi, 
there

are there any functions that make at the end of the each line?(of the form)

Anon

it you store the text in the Var $mBody

$mBody = ereg_replace("\n", " ", $mBody);

done and done

Anon

No!! Don't do that!

Use nl2br() (http://www.php.net/nl2br)

I always have problems using nl2br()

the newline break is replaced for ' ' and if you look at the source code when printing the returned string it still has a line break in it which is a disaster when you save the variable to a textfile!

I always use this:
$text = ereg_replace("\n"," ",$text);
$text = ereg_replace("\r","",$text);

Why do I read so often not to do this and use nl2br()?

nl2br() changes "\n" to " \n"

That is the desired behavior (" " being a valid HTML 5.0 aka XHTML 1.0 element).

In 99% of cases, this is the function to use for converting newline characters to HTML line breaks - because 99% of the time, leaving the newline character in there improves code readability and doesn't really matter.

In your case, where you are saving to a text file, you don't want the newlines left in. So you should use str_replace("\n", nl2br($myString)).

Don't use ereg_replace() or eregi_replace() for something as trivial as stripping new lines. Use str_replace(), which doesn't have the overhead of a regex engine.
