I'm starter. I want to know what will happen if we don't close the MySQL connection. 1- Is it possible to open more than one database if we don't close them? I mean can we open more than one database in a same time? 2- Does closing database increase the speed? 3- Is it necessary to close the database or it is optional? Look at this code. I don't use "mysql_close()" so I don't close the database after each request. There are a lot of requests for this PHP page. Maybe 50000 per each minute. I want to know closing database is necessary for this code or no? <?php //Include the file that lets us to

问题 I've been using the same DB abstraction library for years. But today it started writing these Notice (8) messages in my log. The application is working correctly but every time a script connects to the DB the same notice is logged. I cannot think what might have changed. This is happening on my local dev machine.

问题 I have a form where the user enters their database information and can click a link that uses AJAX to send the credentials to this page. The problem I have is that as long as they enter the correct host name the script returns TRUE . Is there another way to test this so that it will return FALSE if the username and password are not valid? $h = urldecode($_GET['h']); $u = urldecode($_GET['u']); $p = urldecode($_GET['p']); $con = mysql_connect($h, $u, $p); if(!$con){ echo 'Could not connect'; }

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 3 years ago . I have this doubt, I've searched the web and the answers seem to be diversified. Is it better to use mysql_pconnect over mysql_connect when connecting to a database via PHP? I read that pconnect scales much better, but on the other hand, being a persistent connection... having 10 000 connections at the same time
