An example of apachetomcat image storage and browsing Linux+Apache+PHP+MySQL

Note that the table structure used in this program is:
Use test;
create table image(
filename varchar(50),
filesize int, filetype varchar(50),
filesize data longblob

The above introduces an example of apachetomcat image storage and browsing in Linux+Apache+PHP+MySQL, including the content of apachetomcat. I hope it will be helpful to friends who are interested in PHP tutorials.
