Detailed steps to quickly set up wamp development environment

Introduction: Summary of building a PHP development environment (Apache PHP MySQL) in a Windows environment

Installing Apache

1. Download Apache, address: http://www.apache.org/, as shown below:

2. Unzip the compressed package , it is best to put it in the root directory of the disk, otherwise it is easy to report a path error during configuration. I changed the folder name here to facilitate future configuration, as shown below:

Install PHP

1. Download the PHP compressed package at: https://windows. php.net/download , I downloaded the PHP7.0 Thread Safe version, as shown below:

2. Unzip the compressed package. After I unzipped it, it is as follows:

##Installing MySQL

1. The MySQL55 version I installed. I will not introduce the installation method of MySQL here. You can search online by yourself

2. MySQL official download address:
https://dev.mysql.com/downloads/installer/ 3. MySQL default installation directory is as follows:

Configuring MySQL

1. Check in environment variable page

The specific operations are as follows: I Computer-right-click-Properties-Advanced System Settings-Environment Variables
2. Create a new MYSQL_HOME variable, the value is the installation path of MySQL, as shown below:

3. Edit the path system variable and add %MYSQL_HOME%\bin to the end of the path variable
4. Start MySQL and enter: start mysqld on the command line, as follows Picture:

Configuring PHP

1. Open the PHP installation directory Copy php.ini-development first, then change php.ini-development to php.ini and save it

2. Open php.ini to modify the configuration and find; extension_dir = “ext” and change it to extension_dir = "ext directory", for example extension_dir = "D:\Software\php7\ext", as shown below:

3. Open several commonly used extensions, for example: Find extension=php_mysqli.dll and remove the preceding semicolon. Open the libraries in the picture below:

Configuring Apache

1. Open the Apache installation directory and find the conf file folder and open the httpd.conf file
2. Find the "Define SRVROOT" item and change the value in the quotation marks to the installation directory of Apache, as shown below:

3. Add support for PHP and PHP installation path at the end of the file, as shown below:

##The code is as follows:

# php7 support
LoadModule php7_module "D:/软件/php7/php7apache2_4.dll"
AddType application/x-httpd-php .php .html .htm

# configure the path to php.ini
PHPIniDir "D:/软件/php7"

Start Apache service

1. Set environment variables

右键我的电脑,属性->高级,找到最下面的环境变量按钮，选中当前用户的PATH变量,编辑新建以下条目: 

D:\Apache24\bin 

D:\软件\php7 

D:\软件\php7\ext 

2、安装apache服务 

以管理员身份打开命令行,执行httpd.exe -k install 

3、启动服务 

找到apache的安装目录下的bin文件夹，双击ApacheMonitor.exe，双击之后apache就开启了。 

可以在任务栏选择下图图标，右键打开Apache Service Monitor窗口，进行Apache服务的管理 

4、此时在浏览器地址栏输入localhost，回车后就会出现apache的界面，如下图：

5、接下来在 Apache安装目录/htdocs的目录下新建一个phpinfo.php文件，内容为：

<?php
phpinfo();
?>

保存后，在浏览器输入127.0.0.1/phpinfo.php，回车，出现关于PHP的版本信息，如下图：

至此php环境搭建完成，可以将php文件放入htdocs文件夹中运行了

踩到的坑

1、浏览器输入对应PHP地址后，无法解析php 
解决：在命令行输入httpd -t，可以查看是不是Apache的启动问题，如下图： 

可以看到，报错信息是说找不到PHP安装目录下的php7apache2_4.dll文件，通过网上查后我下载的PHP版本不对，应该下载Thread safe 版本。
