I had paid VPS for 1 month and everything i created i've tested it on the VPS. But now i want to make that on my WAMP, so i have installed WAMP.
My tables on the site depends from my mysql base, but they are not shown because there is some error with connecting to MySQL.
MySQL connection php file:
<?php
$username = "root";
$password = "";
$hostname = "localhost";
//connection to the database
$dbhandle = mysql_connect($hostname, $username, $password)
or die("Unable to connect to MySQL");
echo "Connected to MySQL<br>";
?>
Is there something that i need to change in the wamp settings to enable connection ?
Try this order
<?php
$hostname = "localhost";
$username = "root";
$password = "";
//connection to the database
$dbhandle = mysql_connect($hostname, $username, $password)
or die("Unable to connect to MySQL");
echo "Connected to MySQL<br>";
?>
Sometimes, you should follow the order of dbhandle values.

I`m working on a java swing app. so that i have created a database called c_app in MySQL server workbench. what i need is to fetch data into a HTML page using PHP.
$username = "root";
$password = "";
$hostname = "localhost:3307";
$db = "c_app";
//connection to the database
$dbhandle = mysqli_connect($hostname, $username, $password, $db)
or die("Unable to connect to MySQL");
This code segment gives me Warning: mysqli_connect(): (HY000/1049): Unknown database 'c_app' in C:\xampp\htdocs\C_AppWeb\linkpage.php on line 7
Unable to connect to MySQL
What is the problem here? do i need phpmyadmin database rather than MySQl database? can anyone help me?
First one, both phpmyadmin and workbench are not database. They are tools to work with database.
I see you use port 3307 in your code, so let you try:
$username = "root";
$password = "";
$hostname = "localhost";
$port = 3307;
$db = "c_app";
//connection to the database
$dbhandle = mysqli_connect($hostname, $username, $password, $db, $port)
or die("Unable to connect to MySQL");
I have a MySQL database and I am trying to figure out how to access it with a php file. I keep getting an error, so I was wondering if that was because my hostname is incorrect. If so, could anyone help me identify exactly what it is? The database is hosted on this website: https://christopherliao2002.000webhostapp.com/.
Below is my HTML code.
<?php
//Step1
$db = mysqli_connect('localhost','***********','password','******')
or die('Error connecting to MySQL server.');
?>
<html>
<head>
</head>
<body>
<h1>PHP connect to MySQL</h1>
<?php
//Variables
$servername = "localhost";
$username = "*****";
$password = "****";
$dbname = "******";
//Connection to database
$conn = new mysqli($servername, $username, $password, $dbname);
//Test connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
echo "Connected successfully";
</body>
</html>
Try this format
$servername = "localhost"; // This is fixed for 000webhost.
$username = "id***_name";
$password = "****";
$dbname = "id***_name";
Try this without the try / catch:
//Variables
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database_name";
//Connection to database
$conn = new mysqli($servername, $username, $password, $dbname);
//Test connection
if (!$conn) {
die("Connection failed: " . mysqli_connect_error());}
Reference: https://www.w3schools.com/php/php_mysql_connect.asp
Here the problem is with your hostname. Normally the hostname will be 'localhost' and in 000webhost the hostname is something like mysql#.000webhost.com and '#' needs to be replaced with the number for that you need to check your hosting providers members area.
And please don't post your username and password publicly
$db = mysqli_connect('mysql#.000webhost.com','xxxxx','password','xxxxxx')
or die('Error connecting to MySQL server.');

I am new to php/sql and i have a login system which runs on my local host using xammp and it all works fine. I now want to upload it to my website but the code no longer works... I have created a sql db on my hosting service and tried to change the code.
the code that is used on the local host is
<?php
$dbServername = "localhost";
$dbUsername = "root";
$dbPassword = "";
$dbName = "loginsystem";
$conn = mysqli_connect($dbServername, $dbUsername, $dbPassword, $dbName);
and this is the code that i have got from my hosting.
<?php
$host_name = 'db682827654.db.1and1.com';
$database = 'db682827654';
$user_name = 'dbo682827654';
$password = '<Enter your password here.>';
$conn = mysql_connect($host_name, $user_name, $password, $database);
if (mysql_errno()) {
die('<p>Failed to connect to MySQL: '.mysql_error().'</p>');
} else {
echo '<p>Connection to MySQL server successfully established.</p >';
}
?>
however this brings up an errror message. I have changed the password to the password for my database but its still not connecting.
This is the error message.
Failed to connect to MySQL: Access denied for user 'dbo706265806'#'217.160.62.78' (using password: YES)
Any help would be greatly appreciated
use mysqli_connect (not mysql_connect) like localhost:
<?php
$dbServername = "db682827654.db.1and1.com";
$dbUsername = "dbo682827654";
$dbPassword = "<Enter your password here.=)>";
$dbName = "db682827654";
$conn = mysqli_connect($dbServername, $dbUsername, $dbPassword, $dbName);
?>
On your computer you are using mysqli_connect, but on the server you are trying to use mysql_connect. Just use the same file from your computer and simply change $dbServername, $dbUsername, $dbPassword and $dbName to match those that your hosting provided.
I typically connect using the following:
$db_host = "localhost";
$db_username = "bill";
$db_pass = "mypassword";
$db_name = "theDB";
mysql_connect("$db_host","$db_username","$db_pass", TRUE) or die(mysql_error());
mysql_select_db("$db_name") or die("no database by that name");
I tried changing the host to the RDS endpoint below with no luck:
$db_host = "mysql7.1234567890123.us-west-2.rds.amazonaws.com";
-The security group has inbound rules that allow my IP.
-I've tried adding "10.0.0.0/8" to the security group from Connecting From PHP Server to MySQL Server on Amazon AWS
Other info: http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/create_deploy_PHP_legacy.rds.html
There are couple of things and use PDO or mysqli to connect. If you've made sure that you can connect to RDS by setting the right security group, then you've got the main issues squared away.
Connect to Amazon RDS with this in PHP:
$dbhost = $_SERVER['RDS_HOSTNAME'];
$dbport = $_SERVER['RDS_PORT'];
$dbname = $_SERVER['RDS_DB_NAME'];
$dsn = "mysql:host={$dbhost};port={$dbport};dbname={$dbname}";
$username = $_SERVER['RDS_USERNAME'];
$password = $_SERVER['RDS_PASSWORD'];
$dbh = new PDO($dsn, $username, $password);
$link = mysqli_connect($_SERVER['RDS_HOSTNAME'], $_SERVER['RDS_USERNAME'], $_SERVER['RDS_PASSWORD'], $_SERVER['RDS_DB_NAME'], $_SERVER['RDS_PORT']);
Example 1. Example using PDO to connect to an RDS database
$dsn = 'mysql:host=mydbinstance.abcdefghijkl.us-east-1.rds.amazonaws.com;port=3306;dbname=mydb';
$username = 'sa';
$password = 'mypassword';
$dbh = new PDO($dsn, $username, $password);
Example 2. Example using mysqli_connect() to connect to an RDS database
$link = mysqli_connect('mydbinstance.abcdefghijkl.us-east-1.rds.amazonaws.com', 'sa', 'mypassword', 'mydb', 3306);
if nothing works, launch a mysql client like navicat or mysql workbench (free) and punch in all the necessary fields and try to connect and see if it loads the db.
This ended up working for me. Thanks for you help!
$db_host = 'instance2.123456789.us-west-2.rds.amazonaws.com:3306'; //RDS Endpoint...
$db_username = 'myusername';
$db_pass = 'mypassword';
$db_name = 'myDB';
mysql_connect("$db_host","$db_username","$db_pass", TRUE) or die(mysql_error());
mysql_select_db("$db_name") or die("no database by that name");
my I am trying to make login registration page in php.
apache and mysql is up and running.
I am executing the following code
<?php
$db_host = "localhost:777";
$db_username = "root";
$db_pass = "";
$db_name = "login";
mysql_connect("$db_host","$db_username","$db_pass") or die ("could not connect to mysql");
mysql_select_db("$db_name") or die ("no database");
?>
I am using localhost:777 because port 80 is being used by skype.
phpMyAdmin is up and running.
The output i am getting is nothing but the above code only.
can anyone help me on this issue?
Use MySQLi or PDO not MySQL.
You're passing the variables as a string using " " in the mysql_connect function
The syntax is as follows: mysqli_connect(host,username,password,dbname,port,socket);
<?php
$db_host = "localhost";
$db_port = "777";
$db_username = "root";
$db_pass = "";
$db_name = "login";
$conn = mysqli_connect($db_host,$db_username,$db_pass,$db_name,$db_port);
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
?>
Try that and it should work. Please make sure you understand the code above and the error you made. Do not simply copy and paste please you will not learn from it.
