PHP uses the COPY function to update the configuration file

This article mainly introduces how PHP uses the COPY function to update the configuration file, and involves related techniques for the copy function to update configuration information. I hope to be helpful. The example in this article describes how PHP uses the COPY function to update the configuration file. Share it with everyone for your reference.

The details are as follows:

_saveconfig.php file is as follows:

<?php
/*
 * File: _saveconfig.php
 * 
 * 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;]),

   $done = file_put_contents($dstFile, $content);
   copy($dstFile, &#39;../&#39;.$dRootDir.&#39;config.php&#39;);
?>

config.php configuration The file is as follows:

<?php
