This is a problem with the dbopen() function in Microsofts ntdblib library, and not a problem within the PHP extension.

I'll add some length checks to the host parameter for mssql_connect() and mssql_pconnect() to prevent this from happening.

The problem does not exists in php_dblib.dll (the same extension compiled with FreeTDS version of the dblib library).

We are sorry, but we can not support PHP 4 related problems anymore.
Momentum is gathering for PHP 6, and we think supporting PHP 4 will
lead to a waste of resources which we want to put into getting PHP 6
ready.
