From 101c9dc4f6c1189fdb38c464d50773f56b5e7bb9 Mon Sep 17 00:00:00 2001 From: Robert Sesek Date: Sun, 19 May 2013 14:41:02 -0400 Subject: [PATCH] Remove the database abstraction layer and write a new PDO backend. PDO is the future and what Hoplite requires. This hacks in a new DB_Abstract-like backend that uses PDO instead of the mysql_* family of functions. --- framework/db_mysql.php | 261 ------------------------ framework/{db.php => db_mysql_pdo.php} | 225 +++++--------------- framework/db_mysqli.php | 167 --------------- framework/db_postgresql.php | 271 ------------------------- includes/init.php | 3 +- 5 files changed, 49 insertions(+), 878 deletions(-) delete mode 100755 framework/db_mysql.php rename framework/{db.php => db_mysql_pdo.php} (64%) delete mode 100755 framework/db_mysqli.php delete mode 100755 framework/db_postgresql.php diff --git a/framework/db_mysql.php b/framework/db_mysql.php deleted file mode 100755 index 04a96d7..0000000 --- a/framework/db_mysql.php +++ /dev/null @@ -1,261 +0,0 @@ -load('db', null); - -/** -* MySQL Database Abstraction Layer -* -* This framework is a function wrapper for MySQL functions so we can have -* better error reporting and query reporting. -* -* @author Blue Static -* @copyright Copyright (c)2002 - [#]year[#], Blue Static -* @version $Revision$ -* @package ISSO -* -*/ -class DB_MySQL extends DB_Abstract -{ - /** - * Command mapping list - * @var array - * @access private - */ - var $commands = array( - 'pconnect' => '$this->command_mysql_pconnect', - 'connect' => '$this->command_mysql_connect', - 'query' => '$this->command_mysql_query', - 'error_num' => 'mysql_errno', - 'error_str' => 'mysql_error', - 'escape_string' => '$this->command_mysql_escape_string', - 'escape_binary' => '$this->escape_binary', - 'fetch_assoc' => 'mysql_fetch_assoc', - 'fetch_row' => 'mysql_fetch_row', - 'fetch_object' => 'mysql_fetch_object', - 'free_result' => 'mysql_free_result', - 'insert_id' => 'mysql_insert_id', - 'num_rows' => 'mysql_num_rows', - 'affected_rows' => 'mysql_affected_rows' - ); - - // ################################################################### - /** - * Constructor - */ - function __construct(&$registry) - { - parent::__construct($registry); - } - - // ################################################################### - /** - * (PHP 4) Constructor - */ - function DB_MySQL(&$registry) - { - $this->__construct($registry); - } - - // ################################################################### - /** - * Wrapper: mysql_pconnect - * - * @access protected - * - * @param string Server name - * @param string User name - * @param string Password - * @param string Database - * - * @return integer DB-Link - */ - function command_mysql_pconnect($server, $user, $password, $database) - { - $link = mysql_pconnect($server, $user, $password); - $this->select_db($database, $link); - - return $link; - } - - // ################################################################### - /** - * Wrapper: mysql_connect - * - * @access protected - * - * @param string Server name - * @param string User name - * @param string Password - * @param string Database - * - * @return integer DB-Link - */ - function command_mysql_connect($server, $user, $password, $database) - { - $link = mysql_connect($server, $user, $password, true); - $this->select_db($database, $link); - - return $link; - } - - // ################################################################### - /** - * Wrapper: mysql_select_db - * - * @access protected - * - * @param string Database name - * @param integer DB-Link - */ - function select_db($database, $link) - { - if (!mysql_select_db($database, $link)) - { - $this->error('Cannot use the database \'' . $database .
