ecshop适应在PHP7的修改方法解决报错的实现


Posted in PHP onNovember 01, 2016

ecshop这个系统,到目前也没见怎么推出新版本,如果是新项目,不太建议使用它。不过,因为我一直以来都在使用中,所以不得不更改让其适应PHP新版本。现在PHP 7已经出发行版了,所以更改来继续使用吧。具体的更改有以下方面:

(1)将mysql扩展的使用替换掉,改为使用mysqli或pdo:

从php5.5开始,mysql扩展将废弃了。

具体更改的文件在于includes/cls_mysql.php。这是个不小的工程,文件代码太长……

if (!defined('DITAN_ECS'))
{
  die('Hacking attempt');
}

class cls_mysql
{
  var $link_id  = NULL;

  var $settings  = array();

  var $queryCount = 0;
  var $queryTime = '';
  var $queryLog  = array();

  var $max_cache_time = 300; // 最大的缓存时间,以秒为单位

  var $cache_data_dir = 'temp/query_caches/';
  var $root_path   = '';

  var $error_message = array();
  var $platform    = '';
  var $version    = '';
  var $dbhash     = '';
  var $starttime   = 0;
  var $timeline    = 0;
  var $timezone    = 0;
  // 事务指令数
  protected $transTimes = 0;

  var $mysql_config_cache_file_time = 0;

  var $mysql_disable_cache_tables = array(); // 不允许被缓存的表,遇到将不会进行缓存

  function __construct($dbhost, $dbuser, $dbpw, $dbname = '', $charset = 'gbk', $pconnect = 0, $quiet = 0)
