**Should You Explicitly Close MySQL Connections?**

Is MySQL Connection Closure Necessary (mysql_close())?

While establishing database connections (mysql_connect), the question of whether subsequent connection closure (mysql_close()) is mandatory arises.

Does mysql_connect Automatically Close Connections?

As per MySQL documentation, "Using mysql_close() isn't usually necessary". Non-persistent connections opened using mysql_connect are terminated automatically when the script concludes.

Recommendation:

Despite the built-in closure mechanism, it's a common best practice to explicitly close connections using mysql_close(). This ensures that resources are gracefully released, preventing potential memory leaks and performance issues.

Additional Considerations:

  • Persistent connections require explicit closure (mysql_close()) to prevent connection pooling.
  • In case of multiple concurrent mysql_connect calls without matching mysql_close(), the server may terminate the script with an "out of memory" error due to resource exhaustion.
