odbc_data_source — Returns information about available DSNs
$odbc
, int $fetch_type
): array|falseThis function will return the list of available DSN (after calling it several times).
odbc
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
.
Returns false
on error, an array upon success, and null
after fetching
the last available DSN.
示例 #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) )
