// Example usage:
// Connect to a ODBC database that exists on your system
$link = odbc_connect("some_dsn_name", "user", "password") or die(odbc_errormsg() );

odbc_data_source — Returns information about available DSNs
Descrição
This function will return the list of available DSN (after calling it several times).
Parâmetros
-
odbc -
O identificador da conexão ODBC. Consulte odbc_connect() para obter detalhes.
-
fetch_type -
The
fetch_typecan be one of two constant types:SQL_FETCH_FIRST,SQL_FETCH_NEXT. UseSQL_FETCH_FIRSTthe first time this function is called, thereafter use theSQL_FETCH_NEXT.
Valor Retornado
Returns false on error, an array upon success, and null after fetching
the last available DSN.
Exemplos
Exemplo #1 List available DSNs
<?php
$conn = odbc_connect('dsn', 'user', 'pass');
$dsn_info = odbc_data_source($conn, SQL_FETCH_FIRST);
while ($dsn_info) {
print_r($dsn_info);
$dsn_info = odbc_data_source($conn, SQL_FETCH_NEXT);
}
?>O exemplo acima produzirá algo semelhante a:
Array
(
[server] => dsn
[description] => ODBC Driver 17 for SQL Server
)
Array
(
[server] => other_dsn
[description] => Microsoft Access Driver (*.mdb, *.accdb)

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
