How to update configuration information with copy function in php

This article mainly introduces the method of updating configuration information by copy function in php. Interested friends can refer to it. I hope it will be helpful to everyone.

The example in this article describes how PHP uses the COPY function to update the configuration file. The details are as follows:

_saveconfig.php file is as follows:

<?php
/*
 * File: _saveconfig.php
 * 
 * Modified: 2010-7-11
 * By:liulang
 * 说明：涉及到两个文件：_saveconfig.php和config.php当对后台的一些全局配置变量进行更新时，
 * 就更改后台的config.php然后通过这个文件更改前台的config.php文件（前后台文件都一样）,
 * 这个是我曾经用过的一个方法，觉得还不错，拿出来与大家分享

  $srcFile = &#39;../&#39;.$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
/*
 * File: config.php

  $gDb = array
  (

    &#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

  );
  $gSite = array
  (
    &#39;siteName&#39; => &#39;公司名&#39;,

  );
  $gUpload = array

  $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;); 
  mysql_query("SET NAMES &#39;gbk&#39;"); 
?>
