Too many php cookies

Will having too many php cookies on a webpage开发者_StackOverflow社区 slow it down a significant amount? On a site I've created I'm considering adding a feature, which would be nice, but require quite a few php cookies to be stored. Will this make the site slower?

It won't, but there is limit for cookie length. Save only necessary informations (security token) and take it from your server instead

If you have a few number of cookies, you won't see any difference.
