Which of the following is the php code used to connect to the database?

What's wrong with the php connection code! & Lt ;? Php $ find = mysql_connect (da7297f80aa7a35ad8418898e99a6156, 121f559f1e06b2889109f0bc8af7e69d, 387d0ee9a9, where is the php connection code to the database!
$ Find = mysql_connect (da7297f80aa7a35ad8418898e99a6156, 121f559f1e06b2889109f0bc8af7e69d, done );
If (! $ Find ){
Echo "database connection failed ";
} Else {
Echo "database connection successful ";
}
$ Data = mysql_select_db (0e55dc7af851d87009b142fcd44757f3, $ find );
Mysql_query ("set name 'utf8 '");
?>
I want to use MD5 encryption instead of database information! However, the browser has no output! What's wrong? For more information, see database s:
------ Solution --------------------
Just encrypt the user password,

Don't even connect to the database with the md5 username and password.
