PHP MySQL problem - php

Whenever I try to run a php script on my website hosted by hostgator, I get this error:
Warning: mysql_connect() [function.mysql-connect]: Unknown MySQL server host 'pieboy13_(user name)' (1) in /home/pieboy13/public_html/quigley/WebContent/Scripts/register.php on line 6
Error: Could not connect to server. Error Unknown MySQL server host 'pieboy13_(user name)' (1)
Where (Username) is my username.
What could cause this?

You are triying to connect to your username! Check your configuration for server url and make sure it points to your mysql server.

Things that can cause this:
You are using the wrong hostname for the mysql server.

Looks like you might have put your database or username into the server argument.

Error in mysql_connect() using ZZEE between two PC

I developed a project in PHP and converted it to project.exe using ZZEE PhpExe, It work fine on one PC where the WAMP is installed.
I connected another PC to the main Server using LAN and share the project.exe that was complied. I was able to open the project on the other PC, but it can't connect to MySql. by show this error
Warning: mysql_connect() [function.mysql-connect]: Can't connect to MySQL server on 'localhost' (10061) in/www/inc/connect.php on line 13
I tried to use Firefox to check and it work without Error or Warning by using browsers. I went to change my connect.php server name to the LAN IP. E.g
$hostname = "localhost"; to $hostname = "192.168.1.3";
After the changes I Re-Compile the project, then another warning:
Warning: mysql_connect(): Host 'DESKTOP-VLU1NVA' is not allowed to connect to this MySQL server in C:\xampp\htdocs\clinicx\inc\connect.php on line 13
Please can someone tell me what to do.
You need to grant the remote PC access to the MySQL-server. Check out the GRANT command for MySQL: http://dev.mysql.com/doc/refman/5.7/en/grant.html
A very insecure way to do this is:
GRANT ALL ON *.* to '<a username>'#'192.168.1.%';
Don't use this for production, make sure to grant access to only what is needed and add a password.

Remote mySQL connection error

I posted this question earlier but only provided a link to the output instead of posting the output here. With the additional details, I trust there will be enough info.
This script works locally on my server but when loaded on a remote server the error shown after the code below is given... Can someone tell me why it works locally and not remotely. A % wildcard has been set for allowed hosts.
<?php
$version_link = mysql_connect('gjinternetsolutions.com', 'gj_Guest', 'Password1');
mysql_select_db("gj_Software", $version_link);
if (mysql_errno())
{
$error = "<p>MySQL error ".mysql_errno().": ".mysql_error()."\n</p>";
die($error);
}
$version_query = "SELECT * FROM `VersionCheck` where `Software`='RedemptionFee'";
$version_result = mysql_query($version_query);
$version_row = mysql_fetch_array($version_result);
if (mysql_errno())
{
$error = "<p>MySQL error ".mysql_errno().": ".mysql_error()."\n<br>When executing:<br>\n$version_query\n</p>";
die($error);
}
$new_version=$version_row['Version'];
$new_URL=$version_row['URL'];
echo "The latest version of the Redemption Fee Module is: ".$new_version;
?>
This is the error that is given from the above script...
Warning: mysql_connect(): Can't connect to MySQL server on 'gjinternetsolutions.com' (4) in /home/nicedayh/public_html/CheckRemoteMySQL.php on line 3
Warning: mysql_select_db() expects parameter 2 to be resource, boolean given in /home/nicedayh/public_html/CheckRemoteMySQL.php on line 4
MySQL error 2003: Can't connect to MySQL server on 'gjinternetsolutions.com' (4)
At first I thought something was wrong with my script but after seeing it work perfectly on the local machine, I am not certain. Several people have tried loading it remotely and had no success so it is not just one remote machine that has an issue.
I think you have to put :3306 after your database location or whatever port your MySQL is on
Are you able to ping gjinternetsolutions.com?
My server in New Zealand recognises this host name, however my server in the US does not. Your A records may have not propagated to your computer yet, or your name servers NS1.GJINTERNETSOLUTIONS.COM and NS2.GJINTERNETSOLUTIONS.COM might be having issues.
A. Is your mysql database listening on the same server/IP that gjinternetsolutions.com is hosted on since that is what you are using to connect to?
B. If it is, is mysql service running on the db server?
C. If it is, is port 3306 open on the firewall to let traffic through?
D. If it is, is your my.cnf file on the db server set to localhost only using bind-address = 127.0.0.1? If so, comment that out.
E. If it's not, do you have mysql database setup to accept connections from a remote server i.e. not localhost?

or if you use a cpanel

One of these is probably the issue. This at least should get somewhere to look.

PHP & MySQL Error: mysqli_connect() [function.mysqli-connect]: (HY000/2005): Unknown MySQL server host

I keep getting the error below once in a while and then it goes away everything works fine. I was wondering how can I correct this problem? And can someone tell me what in hell is causing this problem?
Error.
mysqli_connect() [function.mysqli-connect]: (HY000/2005): Unknown MySQL server host
The error above points to the code below.
$mysqli = mysqli_connect("i.db.8473545.hostedresource.com", "i", "password", "i");
You're probably on a shared hosting environment with an external MySQL server. The error message hints on DNS problems resolving "i.db.8473545.hostedresource.com".
As a temporary fix, find out the IP "i.db.8473545.hostedresource.com" points to and use the IP adress as host name for mysql_connect(). See if you still get the error afterwards.

mysql_connect doesn't work on a certain host

I get this everytime I use mysql_connect() no matter what database I choose:
Warning: mysql_connect() [function.mysql-connect]: Can't connect to MySQL server on 'IP' (111) in filename.php on line 17
A MySQL error has occurred: Can't connect to MySQL server on 'IP' (111)
The exact same file works on my personal website fine. I have tried multiple databases hosted on different servers and it always gives that output.
The database itself is hosted on the same server, but using its full IP in mysql_connect(). Using localhost:port doesn't work either as it says:
Warning: mysql_connect() [function.mysql-connect]: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) in filename.php on line 17
A MySQL error has occurred: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
But using the IP should work as it has worked calling it via the same file hosted on other servers.
This is the code:
$connect = mysql_connect($db_url,$db_user,$db_pass); // connects
if ($connect == false) exit("A MySQL error has occurred: " . mysql_error());
Now since the file works on other servers i am guessing it is something to do with the server it is on and might need something changed. I don't personally have root access to the server (just my part of the shared host). Is there anything I can do i php, editing the php.ini file or something I should pass on to someone with root access?
Edit: Ok it turns out that the server doesn't have access to outside databases, so thats why the IP didn't work. Thanks for all your answers but we have decided simply to change hosting provider. We need to be able to access an outside database.
This is on a hosting service? Check their documentation, there will be something that tells you where to find mysql. It isn't necessarily localhost.
For example, on startlogic.com, you use: yourdomain.startlogicmysql.com
Can you connect using mysqladmin using the same host, username and password?
mysqladmin -h $db_url -u $db_user -p $db_pass
Replace $db_xxxx with real values.
If that works from the same host as your php script, then sudo to the apache User and try the same test. One of those must be failing.
EDIT: nevermind on sudo part, I noticed that you don't have root access.
Something else to try: Use '127.0.0.1' instead of 'localhost'. I have had issues before where mysql stupidly assumed it could silently change 'localhost:' to '/var/run/mysqld/mysqld.sock'.
Your wording is not very clear, I hope you are not thinking you can connect to the same mysql server from any old web server just because you know the IP address and port number. If the web host is at all competent, they have probably firewalled mysql so it is only accessible through their own web servers.

mysql_connect() is not getting to the correct server

I have a system with a globally open mysql connection to the local server. In one of my files I am opening an additional connection to a remote machine.
Wieldly instead of trying to connect to that machine, I get an access denied message from my ISP (it seems to be trying to connect to the database on that machine).
I am trying to connect using:
$cust_conn = mysql_connect($host,'root','##password##');
I have tried subdomain.domain.com:3306, subdomain.domain.com and ip:3306 as the value for $host.
The wierd this is the response i get:
Warning: mysql_connect(): Access denied for user 'root'#'my.isp.com' (using password: YES) in /var/www/html/report/module/sql_view.php on line 19 Error: Could not connect to database:
Any ideas why this would happen? It seems like for some reason my script is attempting to connect to my ISPs server, instead of the one passed in $host.
The host given in the error message is the host it's trying to connect from, not to.
that hostname in the error (my.isp.com) is your client's host...remote root access is often disabled, or perhaps the pass/host combo is wrong
