My summer holiday English composition solves the problem of MySQL Chinese output turning into question marks

So I added: mysql_query("SET NAMES GB2312"); the problem was solved. Mainly a coding issue.
Pay attention to the insertion position of this code. It should be inserted before the code that displays the data, otherwise it will be meaningless. For details, please refer to the PHP program for displaying MySQL data that I released last time.

The above has introduced my summer holiday English composition to solve the problem of MySQL Chinese output turning into question marks, including the content of my summer holiday English composition. I hope it will be helpful to friends who are interested in PHP tutorials.
