Here's a function that will replace the new line with a <BR> UNLESS a <BR> is
already present..
function replace_nl($string) {
// cut the value up by \n's
$lines = explode ("
", $string);
$index=0;
while($lines[$index]) {
$lines[$index] = trim($lines[$index]);
if(substr($lines[$index], strlen($lines[$index]) - 4, 4) != "<br>")
$lines[$index] .= "<br>";
$return_result .= $lines[$index];
$index++;
}
return $return_result;
}
