ingres_pconnect — Open a persistent connection to an Ingres database

### Description

resource ingres_pconnect ([ string `$database` [, string `$username` [, string `$password` [, array `$options` ]]]] )

Open a persistent connection to an Ingres database.

There are only two differences between this function and ingres_connect(): First, when connecting, the function will initially try to find a (persistent) link that is already opened with the same parameters. If one is found, an identifier for it will be returned instead of opening a new connection. Second, the connection to the Ingres server will not be closed when the execution of the script ends. Instead, the link will remain open for future use (ingres_close() will not close links established by ingres_pconnect()). This type of link is therefore called "persistent".

### Parameters

`database`

  The database name. Must follow the syntax:

  [vnode::]dbname[/svr_class]

`username`

  The Ingres user name

`password`

  The password associated with `username`

`options`

  See ingres_connect() for the list of options that can be passed

### Return Values

Returns an Ingres link resource on success or `FALSE` on failure
