PHP: odbc_data_source

Description

array odbc_data_source ( resource connection_id, int fetch_type )

Returns FALSE on error, and an array upon success.

This function will return the list of available DNS (after calling it several times). The connection_id is required to be a valid ODBC connection. The fetch_type can be one of two constant types: SQL_FETCH_FIRST, SQL_FETCH_NEXT. Use SQL_FETCH_FIRST the first time this function is called, thereafter use the SQL_FETCH_NEXT.

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

// 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);
