Is it possible to keep MySQL connection open from the beginning of a php file and close it at the end of that particular script?
If yes please help me because I'm having problem with this:
Prevent clash in MYSQL database
Thank you all.
This is how I open and close connection with my database:
$host = "localhost";
$root = "myusername";
$pass = "mypassword";
$DBname = "mydatabase";
$link = mysqli_connect($host, $root, $pass, $DBname);
function close_connection($link) {
$link ->close();
}
I call the function close_connection() whenever I want to stop the connection with my database. Hope this helps!

I am getting SNAT Port issue. I don't know what to do I am using PHP 7.0 let me show my code
this is my db code
function db_connect() {
$server = 'P:servername'; // this may be an ip address instead
$user = 'username';
$pass = 'pasword';
$database = 'test'; // name of your database
// Create connection
$conn = mysqli_connect($server, $user, $pass, $database);
return $conn;
if (!$conn) {
die("Connection failed: " . mysqli_connect_error());
}
}
I am getting SNAT port issue what should I do?
Using Persistent Connections
If mysqli is used with mysqlnd, when a persistent connection is created it generates a COM_CHANGE_USER (mysql_change_user()) call on the server. This ensures that the re-authentication of the connection takes place.

I've been trying to upload my PHP MySQL(in Dreamweaver) project to a free web-hosting site.
When I logged in, there is an error that appear in dbconn.php file.
The error is shown below:
and here's the code in my dbconn.php file:
<?php
/* php& mysqldb connection file */
$user = 1350048; //mysqlusername to db
$pass = "password"; //mysqlpassword to db
$host = "eskl.freeoda.com"; //server name or ipaddress
$dbname= 1350048; // db name in server freeoda
$dbconn= mysql_connect($host, $user, $pass);
if(isset($dbconn)){
mysql_select_db($dbname, $dbconn) or die("<center>Error: " . mysql_error() . "</center>");
}
else{
echo "<center>Error: Could not connect to the database.</center>";
}
?>
I would really appreciate if anyone can teach me how to solve this.. thanks in advance!
As Kerbholz already stated, don't use mysql_* functions, they are really outdated.
Instead use mysqli:
$servername = "eskl.freeoda.com";
$username = "1350048";
$password = "password";
$database = "1350048";
// Create connection
$conn = new mysqli($servername, $username, $password, $database);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
echo "Connected successfully";
For your error it got mostly something to do your host doesn't allow remote connections. Try to change the serverhost to localhost or 127.0.0.1
I am stuck after writing all the code, the Website just doesn't connect with mysql at all!
I think this code will help
<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";
// Create connection
$conn = new mysqli($servername, $username, $password,$dbname);
?>
write this code in html file and save it as .php
I hope it works
Create a database in phpmyadmin and then write down below code in a file and save it with .php extension
<?php
$db_username = "db_username"; // Your database login username
$db_password = "db_password"; // Your database login password
$db_name = "db_name"; // The name of the database you wish to use
$db_host = "db_host"; // The address of the database. Often this is localhost, but may be for example db.yoursite.com
$conn = new mysqli($db_host, $db_username, $db_password, $db_name);
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
?>
set those 4 variable as per your db details. mysqli_connect_error() will give you error if the connection will not establish
I have created a website for my versity project...But I am asked to add a database in it..That's why I need to know how to add a database via xamp in a website.
Use this code to create a connection to your database from php
<?php
$servername = "localhost";
$username = "root";
$password ="db-password";
$dbname = "db-name";
//create connection
$conn = new mysqli($servername,$username,$password,$dbname);
//check connection
if ($conn->connect_error) {
die("connection failed" .$conn->$connect_error);
}
?>

I'm trying to connect to the MySQL server using MySQLi. It is enabled in the server end where this code runs. I am unable to connect to the server using the following information. Did I miss something? Any help would be appreciated. Thank you.
<?php
// DBInfo
$hostname = "localhost";
$username = "nc5ff";
$password = "Ni\$hant809472";
$dbname = "test";
// DB Connection
$link = mysqli_connect($hostname, $username, $password, $dbname);
/* check connection */
if (!$link) {
header("Connection Failure", true, 777);
}
mysqli_close($link);
?>
You have to escape the password as it contains special php characters (\ and $):
$password = "Ni\\\$hant809472";
Make sure you have all of the information right i don't see anything wrong with the code, but please make sure you have all the information right.
