# dba_popen

(3.0.8 - 3.0.18 only, PHP 4 >= 4.0.0)

dba_popen -- Open database persistently

## Description

``int dba_popen` (string path, string mode, string handler [, ...])`

dba_popen() establishes a persistent database instance for `path` with `mode` using `handler`.

`path` is commonly a regular path in your filesystem.

`mode` is "r" for read access, "w" for read/write access to an already existing database, "c" for read/write access and database creation if it doesn't currently exist, and "n" for create, truncate and read/write access.

`handler` is the name of the handler which shall be used for accessing `path`. It is passed all optional parameters given to dba_popen() and can act on behalf of them.

dba_popen() returns a positive handle or `FALSE`, in the case the open is successful or fails, respectively.
