I am creating a web site using PHP, and need to pass certain strings via a cookie. I use setcookie() to store the cookie and $_COOKIE to retrieve it. All goes well until the stored string contains a backslash (\) or a single or double quote. In that case, when I retrieve the cookie it comes with 3 extra backslashes. Example:
I store Sam's and I get back Sam\\\'s
I store Sam\'s and I get back Sam\\\\\\\'s
This does not happen when I test locally on my own machine; it only started happening when I moved the site over to TCH for beta testing. I can't strip the backslashes out of the retrieved string, because sometimes I put a backslash in myself, as in the second example. I can't use setrawcookie() because it plain forbids such characters in the first place.
Tech support at TCH has declined to help or advise me. What's going on here, and what can I do about it?
