odbc_data_source — Returns information about available DSNs

Descrierea

odbc_data_source ( resource $odbc , int $fetch_type ) : array|false

This function will return the list of available DSN (after calling it several times).

Parametri

odbc: Identificatorul conexiunii ODBC, accesați odbc_connect() pentru detalii.
fetch_type: 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.

Valorile întoarse

Returns false on error, an array upon success, and null after fetching the last available DSN.

Exemple

Example #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);
}
?>

Exemplul de mai sus va afișa ceva similar cu:

Array
(
    [server] => dsn
    [description] => ODBC Driver 17 for SQL Server
)
Array
(
    [server] => other_dsn
    [description] => Microsoft Access Driver (*.mdb, *.accdb)
)

// 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
