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

Question

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");

Could you post some code that directly relates to this error? — Jose Vega

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.
