Text wrapping in php comment script

Hi, I am new in this forum and also new to PHP. Atm I am trying to edit a simple comment script. Everything is done already but one last thing left. I want to make a word wrapping in comment text section. I have tried many ways but I have failed. If someone could help me I would be pleased

Here are the lines from the script:

echo "<div class=\"commentbody\" id=\"$commentrow[0]\">\n

I want the text in this div to be wrapped.

I have tried to asociate it with this script:

$str = "sample text";
echo wordwrap($str,15,"<br />\n",TRUE);

But unfortunatelly, it didn't work. I must have done something wrong.

Any ideas or suggestions?

This is a link of the following free comment script:
http://www.zimmertech.com/tutorials/php/25/comment-form-script-tutorial.php

Therefore, it has many bugs and this is one of them And the author of the script do not respond anymore.

 

Also I have just tried using css 3 property:
word-wrap: break-word;

But this only works in IE. Anyone has any suggestions?

 

I will copy the whole code to make it clear for all:

echo "
<link rel=\"stylesheet\" type=\"text/css\" href=\"comments.css\"/>
";

$commentquery = mysql_query("SELECT * FROM comments WHERE tutorialid='$tutid' ORDER BY date DESC") or die(mysql_error());
$commentNum = mysql_num_rows($commentquery);

echo "<div id=\"currentcomments\" class=\"submitcomment\"><h3 class=\"formtitle\">Comments</h3>\n";
echo "<p class=\"top\">Total: $commentNum (<a href=\"#post\" class=\"link\">comment</a>)</p>\n";

$number = mysql_num_rows($commentquery)+1;
while($commentrow = mysql_fetch_row($commentquery)){
$number--;

$commentbb = BBCode($commentrow[3]);
$commentDate = formatDate($commentrow[4]);

echo "<div class=\"commentbody\" id=\"$commentrow[0]\">\n
<p>$commentbb</p>\n
<p class=\"postedby\">";
if($commentrow[2]){

echo "<b class=\"name\">$commentrow[2]<b class=\"kb\">,</b></b>";
}
echo "<b class=\"date\">$commentDate</b> | <b class=\"number\">#$number</b></p>\n
\n</div>";

}
echo "</div>";
}

 

The wordwrap should work. Maybe you are working with UTF8 text which one of the comments here mentions: http://dk.php.net/manual/en/function.wordwrap.php#83488
