// Example usage:
// Connect to a ODBC database that exists on your system
$link = odbc_connect("some_dsn_name", "user", "password") or die(odbc_errormsg() );
$result = @odbc_data_source( $link, SQL_FETCH_FIRST );
while($result)
{
echo "DSN: " . $result['server'] . " - " . $result['description'] . "<br>\n";
$result = @odbc_data_source( $link, SQL_FETCH_NEXT );
}
odbc_close($link);
Thank you Angelo for point out the code. Though the function doesn't really do what it is supposed to. It returns the entire list of ODBC DSNs.
If you really are looking to get the server type based on just the ODBC, username and password in an environment where the application needs to be aware of different types of databases, use the following code:
$link2 = odbc_connect($dsn , $DBUser, $DBPwd ) or die(odbc_errormsg() );
$result = @odbc_data_source( $link2, SQL_FETCH_FIRST );
while($result)
{
if (strtolower($dsn) == strtolower($result['server'])) {
echo $result['description'] . "<br>\n";
break;
}
else
$result = @odbc_data_source( $link2, SQL_FETCH_NEXT );
}
odbc_close($link2);
// Hope it saves your precious time
