I’m converting a number of html documents into csv files to upload into MySQL – I’m replacing html div’s etc with tabs as necessary in a text editor to get the data into the columns, then pasting into a spreadsheet and saving as CSV. This is working fine
A couple of ‘fields’ have data on more than one line, which in html is achieved by using br’s, leaving these in the CSV displays the data in the required format.
I’ve also produced a script to add/amend data and for the multi line fields I’m using textareas and then outputting using nl2br() which again displays the data as required. But the uploaded data with br’s is displayed in the add/amend script as a continuous line with the br’s.
Question – Is there anything I can do when manipulating the html data to replace the br’s so that they appear as multi lines in the textareas ?
Replace with "\n"
<?
$string="Some stuff <br/> some other";
$string=str_replace("<br/>","\n",$string);
?>
<textarea><?=$string?></textarea>
You can replace with \n instead of br tag

I have this textarea called personalInfos where i fill the infos in following format :
<p><span class="white">1966 - '69</span><br/> text .... </p>
When i submit it to database, it gets saved ok, same format. When i retrieve the code from database to admin textarea it gets filled ok.
My only problem is on front end where i get displayed the code as text not rendered as html code. So basiclly i see it on the page like this :
<p><span class="white">1966 - '69</span><br/>
Most likely you display fetched code parsed processed by htmlentities() or similar function. This is in most cases the way to go to avoid planting i.e. html in comments. So simply stop doing this after fetching (or insert - depends where you do so) and your content will be outputed as literaly HTML and properly processed by web browser.
You should have a look at htmlspecialchars_decode()
Example
$str = '<p><span class="white">1966 - \'69</span><br/> text .... </p>';
echo htmlspecialchars_decode($str);
Also make sure to escape the single quotes as well.
Data that is stored in my mysql database, has the breaks of text input properly, but when retrieved the data no longer has the breaks, and everything is displayed as one string without any <br>. Any idea why this would occur?
The data column is the format text,
for example: in a table there is:
hey
how
do
you
do
After retrieving the data ill echo $mesarray[0][message]; and the result is:
hey how do you do
I want the line breaks to appear, but they dont.
The reason is because HTML does not understand line breaks. They need <br /> tags to break lines.
There is a function called nl2br() which can be used to convert new lines to <br>
echo nl2br($mesarray[0][message]);
I'm getting data from my textarea with the following code
$about_me=mysql_real_escape_string(nl2br($_POST['about_me']));
which
1. Receives data, using $_POST.
2. nl2br makes brakes so If I echo this code to user he will see if there were new lines.
3. mysql_real_escape_string to secure code from mysql injections before entering it to database.
So if I echo this code everything works fine.
But If I edit it again through textarea, php goes to mysql gets data, puts it to textarea and I see <br> signs...
How can I get rid of them while editing my text again in textarea ?

Stop using nl2br(), of course. It's entirely wrong here.
You use nl2br() when you want to output data that contains linebreaks to HTML, not when you want to store it in the database. Store data unchanged, format it for viewing.
If you output it into a <textarea> you don't need to use it either, since textareas display linebreaks (whereas HTML in general does not). For the textarea you need htmlspecialchars(), but apparently this is already happening - otherwise you would not see literal <br> showing up.
<?php
function br2nl($string){
$return=eregi_replace('<br[[:space:]]*/?'.
'[[:space:]]*>',chr(13).chr(10),$string);
return $return;
}
?>
Use this while getting data from database and before printing into textarea .

I have some multi line text saved in MySql database (VARCHAR 255). When i load it, and process it using standard php function "nl2br", it echoes fine (multi line). But, when i load multi line text from database, make it "nl2br" and then send it to javascript (so it gets displayed in textarea), it won't be displayed! What's wrong?
echo "<SCRIPT>FillElements('".$subject."','".$text."');</SCRIPT>";
P.S.
FillElements function:
function FillElements(Sub,Txt)
{
document.getElementById('txtSubject').value=Sub;
document.getElementById('txtMessage').value=Txt;
}
textareas don't actually store the contents in an attribute like value in the same manner as input elements. They actually store the contents in in between the <textarea> and </textarea> tags. Meaning that the contents is actually treated as CDATA in the document.
<textarea>
This is my Content
</textarea>
Produces a text area with "This is my Content" as the contents.
The implication of this is that you cannot use the code you have to alter the contents of a textarea. You have to alter the innerHTML property of the textarea. I have set up a simple example here:
http://jsfiddle.net/wFZWQ/
As an aside, since you are populating the fields using PHP on the creation of the page, why not merely fill the data in the HTML markup, this seems like a long way round to do it.
Also, since you don't appear to be using it, have you seen [jQuery][1] it abstracts alot of things out, so instead of typing document.getElementById("the_id") to get an element you can use CSS selectors and merely write $("#the_id") to get the same element. You also get a load of useful functions that make writing javascript mucxh easier.

Newline tags (<br />) don't cause actual new lines in <textarea>.
You can pass the "real" newlines (\n) to your <textarea>, though.
I created a fiddle for that.
EDIT: For the updated FillElements code:
$subject = "String\nWith\nMultiple\nLines";
printf('<script type="text/javascript">FillElements(%s)</script>',
json_encode($subject)
);
My guess is that your HTML source code looks like this:
<script>FillElements("foo","foo
bar
baz");<script>
Correct?
In JavaScript, strings cannot span multiple lines...
I'm trying to generate an excel file using html in php and responding with an excel Content-type. Everything works fine except new lines within a cell . They are not preserved.
I've tried 
 ;
 ; \r\n ,chr(13).chr(10) and it didn't work.
I'm trying to get the same result from alt + enter from microsoft Excel .
I am generating in a cell content like:
http:\\www.example.com\blah
(Link)
http:\\www.example.com\blah2
(Event) ...
these have to be in a single cell and also converting the link text to hyperlinks would be great :).
I've found a solution here: http://www.bennadel.com/blog/1095-maintaining-line-breaks-in-an-html-excel-file.htm
The solution I found is to add into a
stylesheet:
br {mso-data-placement:same-cell;}
