EDIT: SOLVED
I'm trying to pass some variables for a mysql connection from a separate file. However, they seem to only be coming through in a string and not as variables.
connect.php:
<?php
function connect(){
require ($_SERVER['DOCUMENT_ROOT'].'/db-connect.php');
$conn1 = new mysqli($servername, $username, $password, $dbname);
if ($conn1->connect_error) {
die("Connection failed: " . $conn1->connect_error);
}
echo $conn1->host_info . "\n";
}
connect();
?>
db-connect.php:
<?php
$servername = "localhost";
$username = "-";
$password = "--";
$dbname = "---";
?>
Message coming through:
$servername = "localhost"; $username = "-"; $password = "--"; $dbname = "---";Connection failed: Access denied for user '-'#'localhost' (using password: NO)
notes:
The $password at the end is different that what is in the db-connect.php file. It is an older password that I used to have when I first tried it. Also, the user '-'#'localhost' is an old user and not the user from $username.
Any ideas please and thanks?

Perhaps this way around may work better for you.
<?php
require ($_SERVER['DOCUMENT_ROOT'].'/db-connect.php');
function connect(){
global $servername, $username, $password, $dbname;
$conn1 = new mysqli($servername, $username, $password, $dbname);
if ($conn1->connect_error) {
die("Connection failed: " . $conn1->connect_error);
}
echo $conn1->host_info . "\n";
}
connect();
?>

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 trying to connect to a remote rackspace DB
PHP:
<?php
$servername = "XX.XX.XX.XX";
$username = "username";
$password = "password";
$dbname = "table";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
?>
And I get
Warning: mysqli::mysqli(): (HY000/2002): Connection timed out
Try this
<?php
$servername = "XX.XX.XX.XX";
$username = "username";
$password = "password";
$dbname = "table";
// Create connection
$conn = mysqli_connect($servername, $username, $password, $dbname);
// Check connection
if (mysqli_connect_errno()) {
echo "Failed to connect to MySQL: " . mysqli_connect_error();die();
}
?>
I am using my website database with php mysql_connect but my hosting provider is saying I need to use mysqli_connect.
When I edit connection file and update change method its not working with mysqli.
Currently using this code:
MSQL Method:
$con=mysql_connect("localhost","username","password");
mysql_select_db("databasename");
and for mysqli I am using this code but fail
MYSQLI Method:
$con = mysqli_connect("localhost","my_user","my_password","my_db");
Please help. Why is mysqli not working? Is my method wrong?
Try this:
Example (MySQLi Object-Oriented)
<?php
$servername = "localhost";
$username = "username";
$password = "password";
` $dbname = "myDB";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
echo "Connected successfully";
?>
Example (MySQLi Procedural)
<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";
// Create connection
$conn = mysqli_connect($servername, $username, $password, $dbname);
// Check connection
if (!$conn) {
die("Connection failed: " . mysqli_connect_error());
}
echo "Connected successfully";
?>
SERVER RESPONSE
Error: INSERT INTO epiz_19848473_Liste1 (Rowcount, Level1) VALUES (0, 'any Value')
No database selected
PHP CODE
UPDATE
<?php
$servername = "sql308.epizy.com";
$username = "epiz_19848473";
$password = "huihuibuh";
$dbname = "Liste1";<--UPDATED
// Create connection
$conn = mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "INSERT INTO Liste1 <--UPDATED (Rowcount, Level1)
VALUES (0, 'any Value')";
if ($conn->query($sql) === TRUE) {
echo "New record created successfully";
} else {
echo "Error: " . $sql . "<br>" . $conn->error;
}
$conn->close();
?>
This should work, right?
NEW STATUS
Connection failed: Access denied for user 'epiz_19848473'#'192.168.0.%' to database 'Liste1'
The code is perfectly all right , the problem is with mysql configuration .
Please login to mysql as **root user ** and do the following,
GRANT ALL PRIVILEGES ON . TO 'epiz_19848473'#'192.168.0.%' (use ip of php server)
FLUSH PRIVILIGES;
The above allows the user to connect to mysql table from the ip specified.
you did not defined the database name in the connection
<?php
$servername = "sql308.epizy.com";
$username = "epiz_19848473";
$password = "huihuibuh";
$dbname = "DATABASE_NAME_HERE";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
else you can define define the database name in the connection
$conn = new mysqli($servername, $username, $password, "DATABASE_NAME_HERE");
Just define the dbname,like this:
<?php
$servername = "sql308.epizy.com";
$username = "epiz_19848473";
$password = "huihuibuh";
$dbname = "test"; //You should create this db in mysql
....
You Can Use This:
CREATE TABLE [database_name].[table_name] (
[your_table_things]
);
I am trying to connect to a MySQL database through a php script. It gives me this error from mysql_error(): Access denied for user '#localhost' to database 'userinfo'
userinfo is the database.
my script is this
<?php
$servername = "localhost";
$username = "root";
$password = "'mm'";
$database = "userinfo";
$conn = mysqli_connect($servername, $username, $password);
if (!$conn) {
die("Connection failed: " . mysqli_connect_error());
}
echo "Connected successfully<br>";
mysql_select_db($database) or die(mysql_error());
echo "connected successfully to db:" . $database . "<br>";
?>
you are connecting using
mysqli_
function
and selecting data with
mysql_
avoid using both at the same time. since they're incompatible.
use the mysqli_ alternative instead
mysqli_select_db($conn, $database);
and
mysqli_error($conn)
Please keep in mind this isn't the safest way. But since you have said your learning this it is a start.
<?php
$servername = "localhost";
$username = "root";
$password = "mm";
// Create connection
$conn = new mysqli($servername, $username, $password);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
?>

It appeared you where combining the old mysql in php with the new mysqli
