Hi Dmitry,

AFAIK mysql($typo3_db, $query) is an old function of php2 
(http://museum.php.net/php2/). This is from the php-2.0 doc:

<snip>

$result = mysql($database,$query)

mysql sends a mysql query. Arguments are the database name and the query 
string. ie. <?mysql("MyDatabase" , "select * from table")>. The return value 
from this function is a result identifier to be used to access the results 
from the other mysql_ functions. A result identifier is a positive integer. 
The function returns 0 when no result identifier is created. This is the 
case with any queries that do not return anything, such as create, update, 
drop, insert and delete. The function will return -1 if an error occurs. A 
string describing the error will be placed in $phperrmsg, and unless the 
function was called as @mysql() then this error string will also be printed 
out. This function is only available if mysql support has been enabled in PHP.

Cheers,
