Spacing issue in a html string
On my website I have a section with announcements and now I'm working at a tool which will allow moderators to edit or post new announcements.
When a moderator posts an announcement he has a form with an input for the title and a textbox for the content of the article. I use nl2br() function (to insert HTML line breaks before all newlines) in the variable which contains the content of the article.
So when I insert an article in the database it will look like this:

    First row ...<br />Second row.<br /><br />Regards,<br />Moderators team

When a moderator wants to edit an article I have a textbox which containes the article:

    <textarea name="body" maxlength="1000" cols="105" rows="10"><?php echo str_replace('<br />', "\n", $content); ?></textarea>

If the moderator click save button (whithout making any modification) the article becomes something like this (the number of <br /> tags doubles):

    First row ...<br /><br />Second row.<br /><br /><br /><br />Regards,<br /><br />Moderators team

Can anybody help me to fix this.
