(PHP 4 >= 4.3.0, PHP 5, PHP 7)

odbc_data_source — Returns information about available DSNs

说明

odbc_data_source ( resource $connection_id , int $fetch_type ) : array

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

参数

connection_id: ODBC 连接标识符，详见 odbc_connect()。
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.

返回值

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

范例

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);
}
?>

以上例程的输出类似于：

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