How to convert php emoji to text?

PHP converts emoji emoticons to HTML character entities:

Mobile input allows you to input facial expressions, which are actually encoded by UTF-16, which will be lost in the database storage. Currently, if the database code code is changed to utf8mb4, it can also be saved.

If you do not want to modify others, you can convert these emoticons into HTML character entities and save them.

The code is as follows:

Function utf16_to_entities () {$content = mb_convert_encoding ($content, 'utf-16'); $bin = bin2hex ($content); $arr = str_split ($bin, 4); $l = count ($arr); $str =''; for ($n = 0; $n

= 0xd800 & & '0x'. $arr [$n] = 0xdc00 & & '0x'. $arr [$n + 1]
