odbc_pconnect — Open a persistent database connection
$dsn,$user,$password,$cursor_option = SQL_CUR_USE_DRIVEROpens a persistent database connection.
This function is much like
odbc_connect(), except that the connection is
not really closed when the script has finished. Future requests
for a connection with the same dsn,
user, password
combination (via odbc_connect() and
odbc_pconnect()) can reuse the persistent
connection.
See odbc_connect() for details.
Returns an ODBC connection, 或者在失败时返回 false.
error.
注意: Persistent connections have no effect if PHP is used as a CGI program.
