_saveconfig.php file is as follows:

<?php
  $srcFile = &#39;../&#39;.$dRootDir.&#39;#data/config.php&#39;;
  $dstFile = $dRootDir.&#39;config.php&#39;; 
  $content = file_get_contents($srcFile);
  $arr = array
  (
     array(&#39;SITENAME&#39;, $gSite[&#39;siteName&#39;]),
     array(&#39;SITENAMEEN&#39;, $gSite[&#39;siteNameEn&#39;]),
     array(&#39;SITEKEYWORDS&#39;, $gSite[&#39;siteKeywords&#39;]),
     array(&#39;SITEDESCRIPTION&#39;, $gSite[&#39;siteDescription&#39;]),
     array(&#39;URLPREFIX&#39;, $gUrlPrefix),
     array(&#39;DBHOST&#39;, $gDb[&#39;host&#39;]),
     array(&#39;DBUSER&#39;, $gDb[&#39;user&#39;]),
     array(&#39;DBPWD&#39;, $gDb[&#39;pwd&#39;]),
     array(&#39;DBNAME&#39;, $gDb[&#39;db&#39;]),
     array(&#39;DBPREFIX&#39;, $gDb[&#39;prefix&#39;]),
     array(&#39;DIR&#39;, $gUpload[&#39;dir&#39;]),
     array(&#39;IMAGEWIDTH&#39;, $gUpload[&#39;imageWidth&#39;]),
     array(&#39;IMAGEHEIGHT&#39;, $gUpload[&#39;imageHeight&#39;]),
     array(&#39;CONTACTUS&#39;, $contactus),
     array(&#39;MENUHIDDENp&#39;, $menuhiddenp),
     array(&#39;THEME&#39;, $gTheme),
     array(&#39;DATE&#39;, date(&#39;Y-m-d&#39;)),
     array(&#39;USER&#39;, $dAdminName)
   );
   for ($i = 0; $i < count($arr); $i++)
   {
    $content = str_replace(&#39;~`~&#39;.$arr[$i][0].&#39;~`~&#39;, $arr[$i][1], $content);
   } 
   copy($dRootDir.&#39;config.php&#39;, $dRootDir.&#39;bak.config.php&#39;);
   //copy($dRootDir.&#39;bak.config.php&#39;, &#39;../&#39;.$dRootDir.&#39;config.php&#39;);
   $done = file_put_contents($dstFile, $content);
   copy($dstFile, &#39;../&#39;.$dRootDir.&#39;config.php&#39;);
?>

config.php configuration file is as follows:

<?php
/*

 */
  $gVersion = &#39;1.0&#39;;
  $gDb = array
  (
    &#39;host&#39; => &#39;localhost&#39;,   //主机名
    &#39;user&#39; => &#39;root&#39;,   //用户名
    &#39;pwd&#39; => &#39;&#39;,    //密码
    &#39;db&#39; => &#39;sino&#39;,    //数据库名
    &#39;prefix&#39; => &#39;sin_&#39;  //数据库前缀
  );
  $gSite = array
  (
    &#39;siteName&#39; => &#39;公司名&#39;,   
    &#39;siteNameEn&#39; => &#39;we are the company&#39;,  
    &#39;siteKeywords&#39; => &#39;药物,医药,制药&#39;,  
    &#39;siteDescription&#39; => &#39;公司名是一家从事00方面的公司&#39; 
  );
  $gUpload = array
  (
    &#39;dir&#39; => &#39;uploads&#39;,
    &#39;imageWidth&#39; => &#39;120&#39;,
    &#39;imageHeight&#39; => &#39;*&#39;  
  );
  $contactus = &#39;&#39;;
  $menuhiddenp = "";
  $FROMURL=$_SERVER["HTTP_REFERER"]?$_SERVER["HTTP_REFERER"]:$HTTP_SERVER_VARS["HTTP_REFERER"];
  $dRootDir = &#39;../&#39;;
  $conn = mysql_connect($gDb[&#39;host&#39;],$gDb[&#39;user&#39;],$gDb[&#39;pwd&#39;]);
  mysql_select_db($gDb[&#39;db&#39;]) or die(&#39;database connect error!&#39;);
