PHP Manual
ODBC 函数
Open a persistent database connection

odbc_pconnect

(PHP 4, PHP 5, PHP 7)

odbc_pconnect — Open a persistent database connection

说明

odbc_pconnect ( string $dsn , string $user , string $password [, int $cursor_type ] ) : resource

Opens 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.

参数

See odbc_connect() for details.

返回值

Returns an ODBC connection id or 0 (FALSE) on error.

注释

Note: Persistent connections have no effect if PHP is used as a CGI program.
