WordPress Comment Emoticons Plugin _php tutorial

Some methods have been modified. The expression is read directly from the directory. So now you can easily increase or decrease the image of the expression. Just put the picture in the face directory. However, the Chinese image name is not supported at the moment.

/*
Modify
1. The face directory can be arbitrarily increased or decreased the expression picture (Chinese is not currently supported)
2. Default support JPG, JPEG, PNG, emoji image with GIF format
