Quick help!

Can anyone help me with the following code. It is to strip out tages from within a DIV. I am getting a preg_replace() Unknown modifier '\' error

function strip_selected_tags_by_id_or_class($array_of_id_or_class, $text)
{
   $array_quoted = array_map('preg_quote', $array_of_id_or_class);
   $name = implode('|', $array_quoted);
   $regex = '/<(\w+)\s[^>]*(?:class|id)\s*=\s*([\'"])(?:' . $name .
            ')\2[^>]*>.*</\\1>/isU';
   return(preg_replace($regex, '', $text));
}

// arr is the ID of the DIV
$arr[] = "Occasion";
$text = "";

print_r(strip_selected_tags_by_id_or_class($arr, $text));

Any help would be ace! 🙂

the regex patten must be on one line

Not sure what dagon was getting at - the regex pattern itself contains no line breaks, and whitespace between code has no bearing on its execution.

As for the error, you have an unescaped delimiter ('/' in the code above) towards the end: </\1>/isU . Either escape it with a backslash or pick a different delimiter (the '@' symbol is another common choice it seems).

bad me, my skinny window was breaking it.
