According to the MySQL documentation, most identifiers (names of databases, tables, columns, indices, etc.) are limited to only 64 characters. You can see the table detailing the various identifiers and their allowed lengths toward the bottom of https://dev.mysql.com/doc/refman/5.7/en/identifiers.html

The MySQL command is "CREATE DATABASE [dbname]" with "[dbname]" replaced with your desired database name.
You can do that using the mysql_connect() function. For example: <?php $host='localhost'; //Your Host Name Here $username='root'; //MySQL Username $pass='';//MySQL Password $dbname='codenair'; //your Database Name //Connecting Database mysql_connect($host,$username,$pass)or die('Failed to Connect'); //Selecting Database mysql_select_db($dbname)or die('Database Not Found'); echo 'Connected'; ?>
Wikipedia uses a MySQL database.
Here is a simple script that you can do to run a MySQL query after you have set a database up. <?php // Database Settings $db['hostname'] = "localhost"; $db['username'] = "<db username>"; $db['password'] = "<db password>"; $db['database'] = "<db name>"; // Connect to MySQL $connect = mysql_connect($db['hostname'], $db['username'], $db['password']); // Select Database mysql_select_db($db['database'], $connect); // Do MySQL Query mysql_query("INSERT INTO table_name SET field_name = '1234567890'"); // Close MySQL mysql_close($connect); ?> Obviously you will need to use your own MySQL settings and database details, but this gives you a general overview of how you can do it.
