Script ec (2); script

I won't talk about the PHP syntax. Let's talk about connecting to mysql!

The Code is as follows:
$ Conn = @ mysql_connect ("localhost", "root", "mydown") or die ("Database Link error "); Mysql_select_db ("bbs", $ conn ); Mysql_query ("set names 'gbk '");

The first statement describes the database connection statement. If a database connection error is prompted, the preceding three parameters indicate the database address localhost, and the database username is root, connect to the Database Password mydown;

The second sentence describes the database that $ conn represents when connected to the database table bbs.

The third sentence is to convert the encoding format to display Chinese characters.

After the database is connected, let's take a look at how database statements are submitted and run in PHP!

The Code is as follows:
$ SQL = "INSERT INTO message (id, user, title, content, lastdate) values ('', '$ _ POST [user]', '$ _ POST [title]', '$ _ POST [content]', now ())"; Mysql_query ($ SQL );

We should be familiar with the blue font above, that is, inserting information in the database. The second sentence is to run the statement in the database. Think of variables similar to $ _ POST [title]. You should know that this is the information obtained through Web Page Submission.

Install

The Code is as follows:
Message board installation

Check_install.php

The Code is as follows:

// Obtain the submitted Database Value $ Llcc_server =$ _ POST ['llcc _ Server']; $ Llcc_user_name = $ _ POST ['llcc _ user_name ']; $ Llcc_user_pass =$ _ POST ['llcc _ user_pass ']; $ Llcc_data_name = $ _ POST ['llcc _ data_name ']; // Open the Database Configuration File $ Fp = fopen ("../config. php", 'w '); If (! $ Fp ){ Echo "sorry, try again! "; } // Write File Content $ Outconfig =" $ Outconfig. = '$ server = '; $ Outconfig. = "". $ llcc_server. "; // IP address of the database. If it is local, localhostn is used by default "; $ Outconfig. = '$ server_name = '; $ Outconfig. = "". $ llcc_user_name. "; // database connection username, generally rootn "; $ Outconfig. = '$ server_pass = '; $ Outconfig. = "". $ llcc_user_pass. "; // database connection password. N "; $ Outconfig. = '$ server_data = '; $ Outconfig. = "". $ llcc_data_name. "; // database name n "; $ Outconfig. = "?> "; $ Fw = fwrite ($ fp, $ outconfig ); If ($ fw ){ Echo" Installation complete! Manually delete the install folder in the directory Back to homepage "; } ?>
