########### ##################################
I wrote a text management document last year and I still feel a little uncomfortable. In addition, I applied for a host, so I wrote PHP+MYSQL to manage the article during the test period
With the support of the majority of netizens, the code is now released
Function description:
Basic operations of the article: add, modify, lock, Unlock, recommend, delete and wait
and has powerful functions such as search, comment, recommend to friends, etc., with emphasis on security, beautiful interface and humanized design.
Main file list:
setup.php Installation program, you can use this system after running it!
index.php Display
manager.php Add and manage articles.
change.php Operation on existing articles.
edit_article.php Article modification
commend.php Recommend the article to friends.
read_article.php article reading.
ping.php Post comments on articles.
search.php Article search
type_manager.php Type management
login.php Administrator login.
config.php Main configuration file
func.php Function file
footer.inc, header.inc, nav.inc include files.
list.txt Type list
and some other peripheral programs
Management system demonstration address:
