PHP using the copy function to update the configuration file method, _php tutorial

PHP uses the copy function to update the configuration file method,

This example describes how PHP updates a configuration file using the copy function. Share to everyone for your reference. Specific as follows:

The _saveconfig.php file is as follows:

<?php/* * File: _saveconfig.php * * modified:2010-7-11 * By:liulang * Description: involves two files: _saveconfig.php and config.php when the background of some of the global distribution When the variable is updated, * Change the background of the config.php and then change the foreground config.php file through this file (the former background files are the same), * This is a method I have used, feel good, take it out to share with you * * 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 (' SITENAME ', $gSite [' SITENAME ']), array (' Sitenameen ', $gSite [' Sitenameen ']), array (' Sitek Eywords ', $gSite [' sitekeywords ']), array (' sitedescription ', $gSite [' sitedescription ']), array (' URLPrefix ', $gUrlPr Efix), Array (' Dbhost ', $gDb [' Host ']), array (' DBUSER ', $gDb [' User ']), array (' Dbpwd ', $gDb [' pwd ']), array (' D Bname ', $gDb [' DB ']), array (' Dbprefix ', $gDb [' prefix ']), Array (' dir ', $gUpload [' dir ']), array (' ImageWidth ', $gU pload[' 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 ');? >

The

config.php configuration file is as follows:

<?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 ',//hostname ' user ' = ' root ',//username ' pwd ' = ', '//password ' db ' =& Gt  ' Sino ',//database name ' prefix ' = ' sin_ '//database prefix); $gSite = Array (' siteName ' = ' Company name ', ' sitenameen ' = ' We Are ', ' the ', ' sitekeywords ' and ' = ' drugs,  Pharmaceuticals, pharmaceuticals ', ' sitedescription ' = ' = ' Company name is a company engaged in 00 aspects ');  $gUpload = Array (' dir ' = ' uploads ', ' imagewidth ' = ' + ', ' 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 '");;
