iOS php MySQL supports Unicode emoji insertion question mark question

After the internet has said that the Unicode expression needs mysql5.5.3, my version is MySQL 5.5.38 so is supported, only need to follow the following configuration

Then you can restart the

[Client]default-character-set = utf8mb4[mysqld]character-set-server=utf8mb4collation-server=utf8mb4_unicode_ci[ Mysql]default-character-set = Utf8mb4

In addition, the link of PHP also need to change

Define (' DNS ', ' mysql:host=localhost;dbname=test;charset=utf8mb4 ');d efine (' USR ', ' root ');d efine (' PWD ', ' 123456 '); Define (' Maxlifetime ', 1440); try {      $pdo = new PDO (DNS, USR, PWD);} catch (Pdoexception $e) {      throw new exceptio N (' Connection failed: '. $e->getmessage ());}

This is the way to set it. Yes, I used the post submission to receive it.
