php使用COPY函数更新配置文件的方法

本文实例讲述了php使用COPY函数更新配置文件的方法。分享给大家供大家参考。具体如下：

_saveconfig.php文件如下：

<?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 * * Created: 2010-6-20 * By: liulang (xujiaphp@gmail.com) *  */  $srcFile = "../".$dRootDir."#data/config.php";  $dstFile = $dRootDir."config.php";   $content = file_get_contents($srcFile);  $arr = array  (     array("SITENAME", $gSite["siteName"]),     array("SITENAMEEN", $gSite["siteNameEn"]),     array("SITEKEYWORDS", $gSite["siteKeywords"]),     array("SITEDESCRIPTION", $gSite["siteDescription"]),     array("URLPREFIX", $gUrlPrefix),     array("DBHOST", $gDb["host"]),     array("DBUSER", $gDb["user"]),     array("DBPWD", $gDb["pwd"]),     array("DBNAME", $gDb["db"]),     array("DBPREFIX", $gDb["prefix"]),     array("DIR", $gUpload["dir"]),     array("IMAGEWIDTH", $gUpload["imageWidth"]),     array("IMAGEHEIGHT", $gUpload["imageHeight"]),     array("CONTACTUS", $contactus),     array("MENUHIDDENDIV", $menuhiddendiv),     array("THEME", $gTheme),     array("DATE", date("Y-m-d")),     array("USER", $dAdminName)   );   for ($i = 0; $i < count($arr); $i++)   {    $content = str_replace("~`~".$arr[$i][0]."~`~", $arr[$i][1], $content);   }    copy($dRootDir."config.php", $dRootDir."bak.config.php");   //copy($dRootDir."bak.config.php", "../".$dRootDir."config.php");   $done = file_put_contents($dstFile, $content);   copy($dstFile, "../".$dRootDir."config.php");?>

config.php配置文件如下：

<?php/* * File: config.php *  * Modified: 2010-09-20 * By:admin *  * Created: 2010-6-20 * By: liulang (xujiaphp@gmail.com) *  */  $gVersion = "1.0";  $gDb = array  (    "host" => "localhost",   //主机名    "user" => "root",   //用户名    "pwd" => "",    //密码    "db" => "yinxi",    //数据库名    "prefix" => "sin_"  //数据库前缀  );  $gSite = array  (    "siteName" => "公司名",       "siteNameEn" => "we are the company",      "siteKeywords" => "药物,医药,制药",      "siteDescription" => "公司名是一家从事00方面的公司"   );  $gUpload = array  (    "dir" => "uploads",    "imageWidth" => "120",    "imageHeight" => "*"    );  $contactus = "";  $menuhiddendiv = "";  $FROMURL=$_SERVER["HTTP_REFERER"]?$_SERVER["HTTP_REFERER"]:$HTTP_SERVER_VARS["HTTP_REFERER"];  $dRootDir = "../";  $conn = mysql_connect($gDb["host"],$gDb["user"],$gDb["pwd"]);  mysql_select_db($gDb["db"]) or die("database connect error!");   mysql_query("SET NAMES "gbk""); ?>

希望本文所述对大家的php程序设计有所帮助。
