Solution: modify "C:/Windows/PHP. ini" to search for php_mysql.dll and remove the annotator ";"

Then copy "PHP installation directory/libmysql. dll" and "PHP installation directory/EXT/php_mysql.dll" to "C:/Windows/system32/" and restart Apache.

In addition, when you open phpMyAdmin again, you may prompt:
