To close your MySQL database connection you need to use the mysql_close() function. Please see the example below: <?php mysql_close(); ?> If your connection data is stored in a variable you would close the connection like this instead: <?php mysql_close($db_conn); ?> That's useful for if you're using more than one database connection in a PHP script.
The difference between connect() and pconnect, it is simply like a shop when u entering in shop you will open the door and take your iteam come out and close the door that is called connect() in mysql the connection to the mysql database will be automatically closed when the script terminates. when the door of the shop is already opend and never close it is called pconnect(), open a connection with mysql_pconnect(), the connection will not be closed and will "persist" for future use.
The current latest stable version of MySQL is 8.0. You can check your MySQL version with dbForge Studio for MySQL by following this few steps: in the Database Connection Properties window enter connection settings click Test Connection.

To connect to MySQL in Java, you'll need to include the MySQL Connector/J JDBC driver in your project's classpath. You can establish a connection using the DriverManager.getConnection() method, providing the database URL, username, and password. Here's an example: Connection conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/yourDatabase", "username", "password"); Make sure to handle exceptions and close the connection when done.
To connect MySQL using JCreator, you first need to ensure that you have the MySQL JDBC driver (e.g., mysql-connector-java-x.x.x.jar) added to your project's classpath. Next, use the DriverManager class to establish a connection by specifying the database URL, username, and password in your Java code. Here’s a basic example: Connection conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/yourDatabase", "username", "password"); Make sure to handle exceptions and properly close the connection when done.
The error message "Could not connect to MySQL server" typically indicates that the application is unable to establish a connection to the MySQL database. This can be due to various reasons such as the MySQL server not running, incorrect connection credentials (username, password, host, or port), or network issues preventing access. To resolve this, ensure that the MySQL server is running, verify the connection details, and check firewall settings or network configurations.

In a JDBC program connecting to MySQL, you should select the MySQL Connector/J driver. This driver is specifically designed for MySQL database interaction and implements the JDBC API. You can include it in your project by adding the MySQL Connector/J JAR file to your classpath. Once included, you can establish a connection to the MySQL database using the appropriate JDBC URL and credentials.
Standard C does not provide such a function; it does not even require you to have an internet connection.
