How can I implement voice chat in PHP based website?

Any suggestions for simple voice chat solution for a PHP based website. We already have a text cha开发者_开发知识库t in place, client now wants voice chat too.

Voice chat simply isn't going to happen with PHP. Such a thing requires a dedicated chat server/service; your client may be interested in something like Skype for Business or Google Talk. Both of these things (as I recall) will require an out-of-browser product to be installed.

You could problably use Adobe flash.

PHP can solve a lot of problems but not anything like voice chat.
