Hi there, I am highlighting keywords with the help of pregreplace. This works great with one limitation. If the word that has to be replaced contains a slash, preg throws an error. So far I could not find a fix. Can someone help? Here is the code:

    $pattern = "/\b($words)\b/is";
    $replace = '<span style="background:#FF0000;color:#FCCCCC;">\\1</span>';
    return preg_replace($pattern,$replace,$str);

Thank you in advance, Merlin

Well, a slash has a special meaning inside PHP strings, more so for double quoted strings. Are you correctly escaping the slash as a double slash so that it's not interpreted by the string as an escaped character, as you will need to as the preg_replace will be interpreting it as an escape sequence to match? Thanks, Ash http://www.ashleysheridan.co.uk HI, replacing the delimiter slash by ~ solved the problem. Thank you
