Obtain gravatar Images

Provides a variety of official and user-released code examples. For code reference, you are welcome to exchange and learn that the wordpress Avatar system has always been using the Global Avatar gravatar. I want to use this avatar system in my project. After reviewing wordpress, you can simply modify it to get the gravatar function get_avatar_src you want. This function returns the required Avatar address. Some functions have not yet been implemented. You can change them as needed ....
/**
* Return the avatar address of the user.
*
* @ Param unknown $ id_or_email
* User ID or email address
* @ Param string $ size
* Size
* @ Param string $ default
* Default Avatar
* @ Param string $ alt
* @ Return string
