dbx_connect - Open a connection/database

SYNOPSIS

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

DESCRIPTION

	Opens a connection to a database.

PARAMETERS

	      o $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.

		     o DBX_MYSQL or "mysql"

		     o DBX_ODBC or "odbc"

		     o DBX_PGSQL or "pgsql"

		     o DBX_MSSQL or "mssql"

		     o DBX_FBSQL or "fbsql"

		     o DBX_SYBASECT or "sybase_ct"

		     o DBX_OCI8 or "oci8"

		     o DBX_SQLITE or "sqlite"

	      o $host
		- The SQL server host

	      o $database
		- The database name

	      o $username
		- The username

	      o $password
		- The password

	      o $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:

	      o database
		- It is the name of the currently selected database.

	      o 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
	      ?>

	      o module
		- It is used internally by dbx only, and is actually the module number mentioned above.

oci_password_change - Changes password of Oracle's user

SYNOPSIS

       bool oci_password_change (resource  $connection, string	$username, string  $old_password, string  $new_password)

DESCRIPTION

       resource oci_password_change (string  $dbname, string  $username, string  $old_password, string	$new_password)

	Changes password for user with $username.

	The  oci_password_change(3)  function  is most useful for PHP command-line scripts, or when non-persistent connections are used throughout
       the PHP application.

PARAMETERS

	      o $connection
		- An Oracle connection identifier, returned by oci_connect(3) or oci_pconnect(3).

	      o $username
		- The Oracle user name.

	      o $old_password
		- The old password.

	      o $new_password
		- The new password to be set.

	      o $dbname
		- The database name.

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

EXAMPLES

       Example #1

	      oci_password_change(3) example changing the password of an already connected user

	      <?php

	      $dbase	  = 'localhost/orcl';
	      $user	  = 'cj';
	      $current_pw = 'welcome';
	      $new_pw	  = 'geelong';

	      $c = oci_pconnect($user, $current_pw, $dbase);
	      oci_password_change($c, $user, $current_pw, $new_pw);
	      echo "New password is : " . $new_pw . "
";

	      ?>

       Example #2

	      oci_password_change(3) example of connecting and changing the password in one step

	      <?php

	      $dbase	  = 'localhost/orcl';
	      $user	  = 'cj';
	      $current_pw = 'welcome';
	      $new_pw	  = 'geelong';

	      $c = oci_pconnect($user, $current_pw, $dbase);
	      if (!$c) {
		  $m = oci_error();
		  if ($m['code'] == 28001) { // "ORA-28001: the password has expired"
		      // Login and reset password at the same time
		      $c = oci_password_change($dbase, $user, $current_pw, $new_pw);
		      if ($c) {
			  echo "New password is : " . $new_pw . "
";
		      }
		  }
	      }

	      if (!$c) {  // The original error wasn't 28001, or the password change failed
		  $m = oci_error();
		  trigger_error('Could not connect to database: '. $m['message'], E_USER_ERROR);
	      }

	      // Use the connection $c

	      ?>

NOTES

       Note

	       Changing the password either with this function or directly in Oracle should be done carefully. This is	because  PHP  applications
	      may  continue  to successfully reuse persistent connections by authenticating with the old password. The best practice is to restart
	      all web servers whenever the user password is changed.

       Note

	       If upgrading the Oracle client libraries or the database from a release prior to 11.2.0.3 to version 11.2.0.3 or higher,  oci_pass-
	      word_change(3)  may  give the error "ORA-1017: invalid username/password" unless both client and server versions are upgraded at the
	      same time.

       Note

	       The second oci_password_change(3) syntax is available since OCI8 version 1.1.

       Note

	       In PHP versions before 5.0.0 you must use ocipasswordchange(3) instead. This name still can be  used,  it  was  left  as  alias	of
	      oci_password_change(3) for downwards compatability. This, however, is deprecated and not recommended.
