mysql_connect(): Connection refused - php

I was just wondering if it was possible for certain databases to block SQL accesses through mysql_connect. I recently downloaded XAmpp and created a SQL database using my own computer as a local host and wrote a PHP file that accessed that database.
However, when I tried to change the username and host settings so that Xampp would run the PHP files that would then connect to the external SQL database of a free hosting site that I'm trying to use (biz.co.nf), I got the following error message:
Warning: mysql_connect(): Connection refused in /Applications/XAMPP/xamppfiles/htdocs/...
Right now I'm thinking either:
My login credentials to that database are incorrect, or
Somehow the host blocks SQL accesses from external users, but if I were to load my php code into the server using FileZilla, it should work okay?
Please let me know if this is the case.
I'm also fairly certain I have the right login credentials.
Here's what I have:
$host = "fdb13.biz.nf";
$username = "1764941_login";
$password = ________;
$db_name = "1764941_Login";!
$tbl_name = "Members";
//Connect to server
mysql_connect($host, $username, $password)or die("Cannot Connect!");
mysql_select_db($db_name)or die("Cannot select Database");
with my server settings according to my website...
Of course, I omitted my password.

Connections are refused from remote locations to MySQL for security reasons. You can add your IP Address to enable MySQL to listen from your database by following the instructions in this link - Cyberciti biz tips on enabling remote access to mysql database server In your case, add the IP address of the location where your PHP script.
I would also say that
mysql_connect
is deprecated in PHP. Use mysqli instead. Check the comments in the link - PHP original MySQL API

MySQL connect failed. Can't connect to MySQL server on 'http' (4)

I try to connect my android application using JSON Parser to the web hosting. But whenever I try to connect (even just open using url in the browser) I will get the error message.
<?php
$dbHost = 'http://sql4.000webhost.com/localhost';
$dbUser = 'a6410240_cbetTD';
$dbPass = 'xxxxxx';
$dbName = 'a6410240_cbetTD';
$conn = mysql_connect ($dbHost, $dbUser, $dbPass) or die ('MySQL connect failed. ' . mysql_error());
mysql_select_db($dbName,$conn);
?>
This is my database.php file. The full error message is
Warning: mysql_connect() [function.mysql-connect]: Can't connect to MySQL server on 'http' (4) in /home/a6410240/public_html/database.php on line 8.
I have tried change the $conn but still it didn't worked for me.
Thanks
If your database and application is on same server then use "locahost" in $dbhost.
And if your database and application is on different servers then you need to use IP address or hostname in $dbhost and the database user should be added on database server provided with required privileges.
The problem you are having was already mentioned in one of the comments, this one to be precise.
For your solution to work, all you need to do is omit the part http:// at the beginning and probably /localhost at the end.
The host is only the domain you are referring to. In this case sql4.000webhost.com. With /localhost you tried to already connect to a database, although your configured database is supposed to be a6410240_cbetTD.
MySQL use TCP port 3306 by default
($dbport) and hostname or IP address ($dbhost). For LAMP (Linux-Apache-MySQL-php) you can find a lot of tutorials.
Usually MySQL server listens internal port (which can't be reached via Internet) for security purposes.
If you familiar with docker, you can simply download examples of LAMP solutions from hub.docker.com.

Connecting MySQL database to website with PHP

As the title indicates I'm trying to link my MySQL database to my website using php.
I'm using GoDaddy hosting for the MySQL database and I got this code directly from them and it's still not working for some reason, giving the error below.
Here's my code :
<?php
$hostname = "trdlibrary.db.6253425.hostedresource.com";
$username = "*******";
$password = "*******";
$dbname = "trdlibrary";
$connect = mysqli_connect($hostname, $username, $password, $dbname, 3306) OR DIE ("Unable to connect to database! Please try again later or contact an administrator for help.");
?>
Here's the error :
Warning: mysqli_connect(): (HY000/2002): A connection attempt failed
because the connected party did not properly respond after a period of
time, or established connection failed because connected host has
failed to respond. in C:\xampp\htdocs\searchengine\dbconnect.php on
line 6 Unable to connect to database! Please try again later or
contact an administrator for help.
Can anyone see the issue?.. or is this something I need to contact GoDaddy's support line about.
-- EDIT --
I forgot to mention that I am running the web server off my local machine using XAMPP (so I can run the PHP scripts) but the MySQL server is off-site with GoDaddy, so 'localhost' won't work currently.
-- EDIT #2 --
So I learned that sadly, remote access of MySQL databases to GoDaddy requires a more expensive and 'higher tier' hosting package from them. So I just answered my own question, thanks to those who replied.
You have to setup remote access to databases on Godaddy. You can refer to this page to see how to enable it.

MySQL remote connection with PHP

I'm new to MySQL and PHP and using 5.0 version of php. My requirement is to connect to a MySQL database which is located on another server (www.some-domain.com). My PHP files are located in my local system.
I have remote server database credentials. How do I configure these details into the PHP file ?
Here is my code so far:
mysql_connect("remote server ip", "root", "root123") or die (mysql_error ());
// Select database
mysql_select_db("resource") or die(mysql_error());
// SQL query
$strSQL = "SELECT * FROM resource WHERE resource_type=11";
// Execute the query (the recordset $rs contains the result)
$rs = mysql_query($strSQL);
when i use above code getting below error:
Access denied for user 'root'#'%' to database 'resource'
To connect to your mysql database in another server, you need to get the host, username and password of the database on that particular server. Like,
mysql_connect('server_host', 'server_db_username', 'server_db_password');
mysql_select_db('server_db_name');
Your code is correct. You only need to connect with the server credentials.
There is a possibility, that remote connections are not allowed within MySQL Server access rules, as a common security measure. I suggest you to contact server support team for further details.
Also, I suggest to read this.

PHP Localhost Application connect to server database

I want to ask about how to connect my localhost application (C:xampp/htdocs/myproject) to database at my server host (www.someweb.somedomain)?
Am I possible to do that? If it is, how to connect it at my php config? Right now my config (server.php) is:
<?php
$host = "my web IP public:3306";
$user = "root";
$pass = "";
$db = "dispatcherDB";
$conn = mysql_connect($host, $user, $pass) or die ("Cant connect to mySQL");
mysql_select_db($db);
?>
what I got:
Warning: mysql_connect(): No connection could be made because the target machine actively refused it. in C:\xampp\htdocs\XMS\server.php on line 7
So, what must I filled for $host? I'm trying using website IP, it still can't connect. Maybe there's someone here have experience at this problem?
Sorry for my bad English
If you have cPanel access to the remote server then you need to mention that from which ip addresses it should allow access to MySQL..
In cPanel you will get Remote MySQL under heading Databases:
Clicking Remote MySQL will give you the option to add hosts from where you want to allow connections to your MySQL server:
Also, you can check localhost without specifying port number as value of $host..
Probably Mysql server is not allowed root access from remote servers.

Having trouble with connecting to MySQL database in php

I've made mysql.php file which contain codes to connect to my database.
However, i'm getting this error message over and over again.
Warning: mysql_connect() [function.mysql-connect]: Can't connect to MySQL server on 'localhost' (10061) in C:\CustomerData\webspaces\webspace_00290195\wwwroot\mysql.php on line 7
Warning: mysql_select_db() [function.mysql-select-db]: Can't connect to MySQL server on 'localhost' (10061) in C:\CustomerData\webspaces\webspace_00290195\wwwroot\mysql.php on line 8

Unable to select database
I've checked if my username, host, database, and password were misspelled, but they were all correct.
I've looked around the internet, but couldn't seem to find the right one for my problem.
My mysql.php file contains:
<?php
// Mysql settings
$user = "example_example";
$password = "example";
$database = "example_example";
$host = "localhost";
mysql_connect($host,$user,$password);
mysql_select_db($database) or die( "Unable to select database");
?>
I've changed my user, password and host name to "example".
I just couldn't find the solution for myself, and I need your kind help.
Thank you in advance.
Please try to find out the error by using mysql_error() function as follows :
mysql_connect($host,$user,$password) or die(mysql_error());
mysql_select_db($database) or die(mysql_error());
and then try to find the exact reason for the failure.
Warning: mysql_connect() [function.mysql-connect]: Can't connect to MySQL server on 'localhost' (10061)
here a list of questions you have to do when this error appears:
1.- is mysql running on the server?
1.1.- is mysql running on default port or in a custom port?
1.2 - is mysql accepting connexions (from localhost, from an ip...?
1.3 - your firewall is blocking mysql?
2.- the database exists on the server?
3.- the user:password have access to that database?
3.1- the user:password can log in from localhost, from an ip... from any place that mysql
is accepting?
I think I don't forget anything
Please check first that your mysql server is running properly.
Mysql settings
$user = "example_example";
$password = "example";
$database = "example_example";
$host = "localhost";
$cn=mysql_connect($host,$user,$password);
mysql_select_db($database,$cn);
Please try this it may work
I am not expert of php but this code is working perfectly in my website
if you are getting any error after applying this code then please inform me i will rty to solve the problem.
Thanks
You should provide the connection that need to use from database whle selecting database. Also use single quote instead of double quotes.
<?php
// Mysql settings
$user = 'example_example';
$password = 'example';
$database = 'example_example';
$host = 'localhost';
$link = mysql_connect($host,$user,$password);
mysql_select_db($database,$link) or die( "Unable to select database");
?>
Reference
You have to get the database information first. You posted this problem when you try to connect to your database in your website hosting, right?
So, go to your hosting control panel to get the MySQL database (and take note of where the database is stored on! Sometimes some hosting providers don't use "localhost". Instead, some of them may use 'serverXX.yourhostingprovider.tld' where XX means the server ID), and then change the corresponding variables with the value you've obtained from the hosting control panel.
