One of the biggest changes from PHP5,PHP7 is the removal of the MySQL extension. It is recommended to use mysqli or pdo_mysql. In fact, starting with PHP5.5, PHP begins to prepare to abandon the mysql extension. If you use the mysql extension, you may have seen the prompt "Deprecated: mysql_connect (): The mysql extension is deprecated and will be removed in the future: use mysqli or PDO instead in". Therefore, in future programs, in order to maintain compatibility, we should minimize the use of mysql extensions for database connections.

/ opt/php/bin/phpize

# compile the mysql extension and use mysql native driver as the mysql link library

. / configure-with-php-config=/opt/php/bin/php-config-with-mysql=mysqlnd
