                                  dbx_connect

   (PHP 4 >= 4.0.6)
   dbx_connect -- Open a connection/database

Description

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

   dbx_connect() 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 persistent parameter
   can be set to DBX_PERSISTENT, if so, a persistent connection will be
   created.

   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" (available from PHP 4.1.0)
     * DBX_SYBASECT or "sybase_ct" (available from PHP 4.2.0)
     * DBX_OCI8 or "oci8" (available from PHP 4.3.0)
     * DBX_SQLITE or "sqlite" (CVS only)

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

   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.

   Example 1. dbx_connect() example
   <?php
   $link = dbx_connect(DBX_ODBC, "", "db", "username", "password",
   DBX_PERSISTENT)
       or die("Could not connect");
   echo "Connected successfully";
   dbx_close($link);
   ?>

     Note: Always refer to the module-specific documentation as well.

   See also dbx_close().
