Parameters

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.

Return Values

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.
