So if you have not yet resolved, proceed with the “heavy weapons”  using phpMyAdmin Will change via an SQL the administrator password. Once in phpMyAdmin, press the button SQL  in the top left, under the logo of the program. Now you can write this command in the appropriate box

UPDATE ‘wp_users’ SET ‘user_pass’ = MD5(‘PASSWORD’) WHERE ‘user_login’ =’admin’ LIMIT 1;

Obviously your new password is .. PASSWORD, and of course we recommend you change immeditely at  first access the administrative area of the blog.

mysqldump -h localhost -u username -p database_name > database_backup.sql

Obviously the parameters changed accordingly, localhost should be fine considering the use of the shell, while database_name username must be adjusted accordingly. After the sign > is the name chosen at your discretion. Once given the command will be prompted for a password to access the database to its content.

Can also directly produce a compressed slightly by changing the syntax as follows:

mysqldump -h localhost -u username -p database_name | gzip -9 > database_backup.sql.gz

where performs gzip compression (-9 parameter indicates the best compression possible), this is useful if you download the file through the Internet.

First we need to declare some critical data like username and password, so i strongly recommended to store this value into a different file where php will ask tables and data, this for security reason.

In the php convension, usually we make a file called config.inc.php, because the .inc between the file name and real extension, dont show nothing if directly called to your browser.

Let’s make this file usually called config.inc.php

      <?php
      //database parameters
      $db_host = "localhost"; //usually localhost, but can be an IP
      $db_user = "myusername";
      $db_password = "mypassword";
      $db_name = "mydatabasename";
      ?>

Now we must pass to php this values, if you are planning a project, usually is a good idea to make next step to a file called database.php and perform the connection.

      <?php
      include("config.inc.php");
      //now check our usr/pass credentials
      $db = mysql_connect($db_host, $db_user, $db_password);
      if ($db == FALSE)
      die ("put here an error message");
 
      //now we see if database name can be read/write
      mysql_select_db($db_name, $db)
      or die ("ERROR: your parameteres are wrong");
      ?>

With mysql_connect your have ask a connection to database server with your username and password, usually on shared service, your credentials give access to one database, so the server must reply if you have a valid account on it. Be careful, the variables $db_host, $db_user, $db_password must be passed in the order of example above.

With mysq_select_db you ask the permission to read/write on database name, with previous credentials.
Both functions are native PHP functions, and they can perform only a TRUE or FALSE, no database data is exchanged yet.
