1.1.  停止WAMP伺服器.

2.下載要安裝的PHP版本。下載Window版本的ZIP包啦：http://windows.php.net。解壓到 Wamp的安裝目錄\bin\php\php7.1.0。

3.從已存在的php版本檔案中（如php7.0.4 (eg.   wamp/bin/php/php7.0.4）複製以下檔案: -  php.ini、phpForApache.ini和wampserver.conf到php7.1.0資料夾.

4.開啟php7.1.0資料夾的以下檔案: -   php.ini和phpForApache.ini並且把其中所有的 7.0.4替換為7.1.0。

5.修改Wamp配置檔案：進入 Wamp的安裝目錄

，用IDE或記事本（最好使用行號定位的記事本，如EditPlus等）開啟 wampmanager.ini，定位到 335 行，通常在這一行就是[phpVersion]，如果不是，則在附近找找。複製下面一行：

Type: item; Caption: "5.6.19"; Action: multi; Actions:switchPhp7.0.4
插入到這一行前面，並修改為 Type: item; Caption: "5.6.19"; Action: multi; Actions:switchPhp7.1.0 [switchPhp5.3.0]
Action: service; Service: wampapache; ServiceAction: stop; Flags: ignoreerrors waituntilterminated
Action: run; FileName: "Wamp的安裝目錄/bin/php/php5.6.19/php-win.exe";Parameters: "switchPhpVersion.php 5.3.0";WorkingDir: "Wamp的安裝目錄/scripts"; Flags: waituntilterminated
Action: run; FileName: "Wamp的安裝目錄/bin/php/php5.6.19/php-win.exe";Parameters: "-c . refresh.php";WorkingDir: "Wamp的安裝目錄/scripts"; Flags: waituntilterminated
Action: run; FileName: "net"; Parameters: "start wampapache"; ShowCmd: hidden; Flags: waituntilterminated
Action: resetservices
Action: readconfig; 插入這一段之前，並修改為
[switchPhp7.1.0]
Action: service; Service: wampapache; ServiceAction: stop; Flags: ignoreerrors waituntilterminated
Action: run; FileName: "Wamp的安裝目錄/bin/php/php5.3.0/php-win.exe";Parameters: "switchPhpVersion.php7.1.0";WorkingDir: "Wamp的安裝目錄/scripts"; Flags: waituntilterminated
Action: run; FileName: "Wamp的安裝目錄/bin/php/php5.3.0/php-win.exe";Parameters: "-c . refresh.php";WorkingDir: "Wamp的安裝目錄/scripts"; Flags: waituntilterminated Action: run; FileName: "net"; Parameters: "start wampapache"; ShowCmd: hidden; Flags: waituntilterminated
Action: resetservices
Action: readconfig;
6. 去wamp/bin/apache/apache/apache2.2.11/bin刪除php.ini檔案。
7..重啟wamp.
8.選擇php7.1.0版本，選擇後後會重啟wamp。
9.可以開啟phpinfo察看此時是否有php7.1.0的資訊，然後開啟Phpmyadmin,看是否可以訪問。
10.完成。
