error to connect database, target machine actively refused it - php

Question

I'm developing an application, in which two tables of a database are connected but not the third. (This is on server. They are working fine on my local machine.)
1. Warning: mysql_connect() [function.mysql-connect]: [2002] No
connection could be made because the target machine actively (trying
to connect via tcp://localhost:3306) in D:\Hosting.. on line 5
2. Warning: mysql_connect() [function.mysql-connect]: No connection could be made because the target machine actively refused it. in D:\Hosting.. on line 5
At an earlier stage, I connected to the two tables from the same database successfully, so I've checked the physical location of each table of the database. No wonder all are physically resting at the same place in the database.
Please help me to understand the problem.
EDIT :
//Page1 has something like:
$conid=mysql_connect("dxxs.db.7xx7.hostedresource.com","dxxs","Kxx3") or die();
mysql_select_db("dxxs",$conid) or die();
mysql_query(“some basic 4-5 queries depending on user’s interaction with table1”);
mysql_close($conid);
//redirection to page2 from there to page3
$conid=mysql_connect("dxxs.db.7xx7.hostedresource.com","dxxs","Kxx3") or die();
mysql_select_db("dxxs",$conid) or die();
mysql_query(“some basic 4-5 queries depending on user’s interaction with table2”);
mysql_close($conid);
//some redirection to page4
$conid=mysql_connect("dxxs.db.7xx7.hostedresource.com","dxxs","Kxx3") or die();
mysql_select_db("dxxs",$conid) or die();
mysql_query(“some basic 4-5 queries depending on user’s interaction with table3”);
mysql_close($conid);
Now my problem is when connecting to table 3, the server is throwing an error as
stated above
Where in line 5, MySQL_connect is written. Please help me to understand why table 3 is not getting connected whereas table 1 & table 2 are able to connect. All are resting at the same database on the server.

Answer 1

It sounds like you are calling mysql_connect() once for each table you are working with. You do not need to do this - you only need to connect once for each server you are working with.
The server is probably limiting you to 2 concurrent connections, which is why it is refusing the third.
Try calling mysql_connect() once at the top of your script.

Answer 2

I have found the issue and solved it. Try to use my code using port after hostname:PORT:
$dbh=#mysql_connect('dbxxxxxx.db.1and1.com:3306','db-username','db-password');
if (!$dbh) {
$err_msg='Cannot connect to the database because: '.mysql_error();
}
