It’s very simple and interesting to check the MySQL database connectivity from your account without login as a root. Here is a script to do the same. For checking the database connectivity, you must know the database hostname, normally it is “localhost” then database-name, username and password.
<?php mysql_connect('db_host', 'db_username', 'password') or die('Could not connect the database : Username or password incorrect'); mysql_select_db('db_name') or die ('No database found'); echo 'Database Connected successfully'; ?>
It’s very simple concept, first the “mysql_connect” argument will check the database hostname, username and password. If the first argument is true, then PHP take the second line to execute else the script will die with an output given in the Die section. Similarly, mysql_select_db check the database on the server. If both of the arguments are true then you will get an output given after the echo command.
1, If all of the input data(db_name, username, password, hostname) are right, then the output is like;
Database Connected successfully
2, If any of the entry in ‘mysql_connect’ secion is wrong, then the output is;
Could not connect the database : Username or password incorrect
3, If the database entry is wrong;
No database found
That’s it 🙂
