[PHP] replacing \n with br
Hi, all -- I have a php script which writes comments out to a file in the format field@@comment field@@comment ... and everything has worked delightfully -- until someone put in a newline in one of the items and now we have field@@com ment field@@comment ... and things break. I read the file, line by line, and parse on @@ as my separator, so anything after a newline is lost. I thought I'd just replace that newline with a br since that's what the user really wants, but I can't get rid of the \n while I'm at it; through various attempts at directly replacing or using variables or such like preg_replace(/\n/,br,$mydatastring) ; preg_replace(/$newline/,$linebreak,$mydatastring) ; I get mixed results of field@@combr ment or field@@com brment but in no case have I managed to get field@@combrment which is what I want. Is there a way to turn off the recognition of \n as an end of line and instead operate on the entire $mydatastring?

Re: [PHP] replacing \n with br
Actually on second thought... and I don't know why I went with the
crowd in the first place... I do the following:
$foo = I don't like\nnewlines;
$foo = str_replace( \n, 'br /', $foo );
That one work for you? It's more efficient too.
Cheers,
Rob.

Re: [PHP] replacing \n with br
Why not just use the nl2br() function? It's a lot easier that using any replace function you build yourself.

Re: [PHP] replacing \n with br
Sorry. Since you were looking to use br, I thought you were creating HTML content. But then, line feeds are ignored in HTML so then you wouldn't have a problem with them. I should have thought of that. How are you reading the file? The key being that you said you read it line by line. Once you read a line, could you just grab the first length-1 characters and then do your parsing on that?

Well, yes and no.
% wouldn't have a problem with them. I should have thought of that.
Well, yes and no :-) It's my app, and it's understandable that you don't
already know everything about it from having not seen it yet!
%
% How are you reading the file? The key being that you said you read it
% line by line. Once you read a line, could you just grab the first
% length-1 characters and then do your parsing on that?
The data file format is
field@@data
field@@data
...
and a real example is
comment@@this is a comment
latdir@@N
londir@@W
latdec@@36
londec@@89
...
and my code [now, after mods,] looks like
...
if ( file_exists($filelocation) ) # do we have an info file?
{
$newfile = fopen($filelocation,r);# grab it and start reading!
while ( !feof ($newfile) ) # (go only until the end, of
course)
{
$commentline = trim(fgets($newfile)); # get one line with whitespace
trimmed
if ( $commentline ) # a line with data?
{
list ($field,$data) = preg_split(/@@/,$commentline); # split it
$content[$field] = preg_replace(/br/,\n,$data) ; # replace our swapped
'br's with original '\n's and store it in the hash
}
}
fclose($newfile); # always lock up
}
...
so I'm just using fgets to read it. The reason it looks that way is
because, after the user has had the opportunity to edit the fields and
hits the button, I process the data as
...
$newfile = fopen($filelocation,w);
foreach ($keylist as $k)# loop thru keys
{
fwrite($newfile,$k@@.ereg_replace((\n|\r)+,br,stripslashes(${base64_encode($k)})).\n)
; } # write the clear text out
fclose($newfile);
...
Although I've solved the problem for now, the next version will probably
end the data with a @@ and so I can just read another line if I don't
have a closer.
Thanks again HAND

Ignore me if this has already crossed your mind... but why not
use XML? You format would be extensible and there are utilities
that can process the input for you.
