# dbx_connect

(PHP 4 >= 4.0.6, PHP 5 <= 5.0.5, PECL dbx >= 1.1.0)

dbx_connect — Open a connection/database

### Opis

object dbx_connect ( mixed `$module` , string `$host` , string `$database` , string `$username` , string `$password` [, int `$persistent` ] )

Opens a connection to a database.

### Parametry

`module`

  The `module` parameter can be either a string or a constant, though the latter form is preferred. The possible values are given below, but keep in mind that they only work if the module is actually loaded.

  - `DBX_MYSQL` or "mysql"
  - `DBX_ODBC` or "odbc"
  - `DBX_PGSQL` or "pgsql"
  - `DBX_MSSQL` or "mssql"
  - `DBX_FBSQL` or "fbsql"
  - `DBX_SYBASECT` or "sybase_ct"
  - `DBX_OCI8` or "oci8"
  - `DBX_SQLITE` or "sqlite"
`host`

  The SQL server host

`database`

  The database name

`username`

  The username

`password`

  The password

`persistent`

  The `persistent` parameter can be set to `DBX_PERSISTENT`, if so, a persistent connection will be created.

The `host`, `database`, `username` and `password` parameters are expected, but not always used depending on the connect functions for the abstracted module.

### Zwracane wartości

Returns an object on success, `FALSE` on error. If a connection has been made but the database could not be selected, the connection is closed and `FALSE` is returned.

The returned object has three properties:

database
  It is the name of the currently selected database.
handle

  It is a valid handle for the connected database, and as such it can be used in module-specific functions (if required).

  `<?php
  $link = dbx_connect(DBX_MYSQL, "localhost", "db", "username", "password");
  mysql_close($link->handle); // dbx_close($link) would be better here
  ?>`
module
  It is used internally by dbx only, and is actually the module number mentioned above.
