note 24085 added to function.eregi

I'm trying to put a html newline character after each character in a string. The code worked well until we updated the PHP to 4.2.1 and now I get a REG_EMPTY warning and it doesn't work :- $keywords = ereg_replace("","<br>", $keywords); For example ... Fred would become in html F r e d However, I now get nothing as I'm not allowed to set the incoming character field to "". Can anyone help and tell me what I need to do sort this out ?
