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

odbc_data_sourceReturns 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)
)
