I have created a website that has a MySQL database. I'm using phpmyadmin and xampp. Now I have a website to upload the files to (using Filezilla). How do I upload the MySQL database to the server and connect it to the website? I'm guessing there is already a tutorial somewhere but I couldn't find it.
If you have your database file ready to upload then in phpmyadmin there is an import option as shown in the image below:
In order to connect it to your website will depend on your server side language choice...
Example with PHP to connect your website to your database (using pdo):
<?php
$dsn = 'mysql:dbname=name_here;host=127.0.0.1';
$user = 'root'; //change to your username
$password = '******'; //change to your password
try {
$pdo = new PDO($dsn, $user, $password);
} catch (PDOException $e) {
echo 'Connection failed: ' . $e->getMessage();
exit;
}
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
?>
Once you have that at top of your PHP file you can connect. This one way to do it via PHP.

I'm trying to connect to my MySQL DB located on 192.168.23.140 from my Web Frontend on .23.139
Here is my code :
$servername = "192.168.23.140";
$username = "web";
$password = "rootnetwork";
$dbname = "test";
try {
$conn = new PDO('mysql:host=$servername; dbname=$dbname', $username, $password);
// set the PDO error mode to exception
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
echo "Connected successfully";
}
catch(PDOException $e)
{
echo "Connection failed: " . $e->getMessage();
}
Here is what i get :
Connection failed: SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo failed: Name or service not known
I've been looking for some answers on the internet but none of them work.
Thank you for your help
$variables are not expanded in a single quotes string literal, they are only expanded in a double quoted string literals.
So
$conn = new PDO("mysql:host=$servername; dbname=$dbname", $username, $password);
You will also have to make sure that this MYSQL user account web is setup to allow connections from ip addresses that are not the ip of the machine running MySQL
I want to connect to a MySQL database from PHP but I can't because "authentication method unknown", I found many solution but all of them about creating a new user with the old password type, but according to the PHP documentation, it should support the new password type. So is it possible to use the new MySQL password type with PHP 7.2.7?
Versions
PHP: 7.2.7MySQL Server: 8.0.12
PHP Code
// Create connection
$conn = new mysqli($servername, $username, $password);
$conn->set_charset("utf8");
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
echo "Connected successfully";
Result
Connection failed: The server requested authentication method unknown to the client
i trying to learn php but found an issue.. im using mamp on a windows PC. and when im trying to connect my php with mysql a get this error:SQLSTATE[HY000] [1045] Access denied for user 'root'#'localhost' (using password: YES).....
in mysql i got the info username and password are 'root', host:localhost port:8889
and this is my code..
function connectToDb()
{
try{
return new PDO('mysql:host=localhost; dbname=tutorials','root','root');
}
catch (PDOException $e){
die ($e->getMessage());
}
}
any help will be appreciate.... thanks...
Use this it will work...
$dbhost = 'localhost:3306';
$dbuser = 'guest';
$dbpass = 'guest123';
$conn = mysql_connect($dbhost, $dbuser, $dbpass);
// make the current db as your DB_Name
$db_selected = mysql_select_db('DB_Name', $conn);
add port number also to your code...
mysql:host=localhost:8889
And it will look like this
function connectToDb()
{
try{
return new PDO('mysql:host=localhost:8889; dbname=tutorials','root','root');
}
catch (PDOException $e){
die ($e->getMessage());
}
}
or your credentials will be incorrect ie, try the connection with password=' '.
Hi i have a problem connecting with my Mysql database i have the following code:
<?php
$servername = "dt5.ehb.be";
$username = "TVOSAPP";
$password = "*****";
$dbname = "TVOSAPP";
// Create connection
$conn = mysqli_connect($servername, $username, $password, $dbname);
// Check connection
if (!$conn) {
die("Connection failed: " . mysqli_connect_error());
}
$sql = "SELECT storyId, title, score FROM Stories";
$result = mysqli_query($conn, $sql);
if (mysqli_num_rows($result) > 0) {
// output data of each row
while($row = mysqli_fetch_assoc($result)) {
echo "id: " . $row["storyId"]. "Naam" . $row["title"]. "score" . $row["score"]. "<br>";
}
} else {
echo "0 results";
}
mysqli_close($conn);
?>
which gives the following error:
Connection failed: Access denied for user 'TVOSAPP'#'10.3.101.30' (using password: YES)
I hope you can help me out to solve this problem it would be very much appreciated
the user that you are trying to connect with might not have the permission to connect remotely to the DB. please verify the same. To give remote access you might need to run
grant <privilage name> on TVOSAPP.* to 'TVOSAPP'#'<youripaddress>' identified by <yourpassword>
Ref: http://dev.mysql.com/doc/refman/5.7/en/grant.html
EDIT:
If your IP address is not static then you can use a percentage sign (%) in place of your IP address. However this approach is less secure as it allows any host to connect to the database remotely.
I fixed it about a week ago is had a space too much thats why I couldn't connect thank you all for your responses
I'm having a problem to connect my DB cloud sql with php.
I've tried every possible way to connect (pdo, mysqli & mysql)
none of them worked.
I've put an IPv4 for the could sql instance and authorized the compute engine IP in the allowed networks section.
When I'm trying to connect from the compute engine with
mysql --host=cloud_sql_IP --user=my_user --password
it's working and I'm able to see the tables.
On the php side I've put this code:
$db = mysql_connect(<CLOUD_SQL_IPV4>, 'root', '');
if (!$db){
die('Connect Error (' . mysql_error());
}
and I get "Connect Error (Permission denied)"
when I'm trying this way:
$conn = mysql_connect(":/cloudsql/<COMPUTE_INSTANCE>:<DB>", "root", "");
if (!$conn) {
die('Connect Error (' . mysql_error());
}
I'm getting:
"Connect Error (No such file or directory"
What else should I do?
Thanks!
Well after diggin into it for 2 days I managed to connect cloud DB
first run this for the permission fix (centos)
setsebool httpd_can_network_connect=1
And for the php it should be written this way:
new mysqli(
<IP_V4>, // host
'root', // username
'', // password
<DB_NAME>, // database name
null,
'/cloudsql/<GCE_INSTANCE>:<DB>'
);
