# 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.
