In a character class the only meta-characters are: \ general escape character ^ negate the class, but only if the first character - indicates character range ] terminates the character class So you only have to worry about a minus if you're in a [a-z] range, and even then you can put a minus in without having to resort to backslashes. % Your line of code might be: % % <CODE> % $text = preg_replace('/<!\-\-(.*)\-\->/','',$text); % </CODE> Then, again, it might not ;-) % % This line of code, if you are parsing HTML file row by % row, strips only "one line" comments.
