MYSQL write emoji emoji character processing

This ghost emoji expression is 4 bytes, MySQL uses UTF8 encoding,UTF8 accounts for 3 bytes, to store that emoji expression needs to change the MySQL encoding from UFT8 to UFT8 superset,UTF 8MB4;

It is easy to change the database code to cause large-face garbled disaster. So when encountering emoji character expression, do special treatment. Online also have a lot of processing solutions, finally found a sticker address and code: Https://github.com/BriquzStudio/php-emoji, Thank you
