How to set up an environment for php development website (a brief analysis of the steps)

PHP, as an open source scripting language, has been widely used in the field of Web application development. If you want to set up an environment for PHP technology development website on your own computer, then this article will introduce you how to do it.

1. Install the Web server

In the environment of building a PHP technology development website, we first need to install a Web server. Here we have chosen to use Apache as the web server because it is one of the most popular web servers and has good support in both Windows and Unix systems.

1. Download Apache

We can download the latest version of Apache from its official website. Once the download is complete, double-click the installer to start the installation.

2. Installing Apache

The installer will ask you to select the installation directory for Apache and whether to install Apache as a Windows service. Normally, we select the default options to complete the installation.

3. Start Apache

After the installation is complete, we need to start Apache. You can find the Apache startup program in the start menu or installation directory and double-click it to start it. After startup, we can enter "http://localhost" in the browser to test whether it is running normally. If the browser can display the Apache welcome page, it means that Apache has run successfully.

2. Install PHP

In the environment where we build a PHP technology development website, we need to install PHP next. We can download the latest version of PHP through PHP's official website and follow the steps below to install it.

1. Download PHP

We can download the latest version of PHP from the official website of PHP. After the download is complete, extract it to the "htdocs" folder in the Apache installation directory.

2. Modify the configuration file

In the PHP installation directory, we can find a configuration file named "php.ini". We need to modify this file to configure the PHP environment.

First, find the configuration item "extension_dir" and change its value to the "ext" folder in the PHP installation directory. For example: "extension_dir = C:\PHP\ext"

Secondly, find the configuration item of ";extension=php_mysql.dll" and remove the ";" in front of it. This way PHP can support the MySQL database.

Finally, find the "doc_root" configuration item and change its value to the "htdocs" folder in the Apache installation directory. For example: "doc_root = C:\Program Files\Apache Group\Apache2\htdocs"

3. Testing PHP

After the installation is complete, we need to test whether PHP is working properly. You can find a file named "phpinfo.php" in the installation directory and copy it to the "htdocs" folder.

Enter "http://localhost/phpinfo.php" in the browser, and the browser will display the PHP configuration information.

3. Install MySQL

In the environment where we build a PHP technology development website, we also need a database to store our data. At this time we can choose to use the MySQL database, which is an open source database and has good support in Windows and Unix systems. Following are the steps to install MySQL.

1. Download MySQL

We can download the latest version of MySQL from the official website of MySQL. After the download is complete, run the installer to start the installation.

2. Installing MySQL

The installation program will ask you to select the MySQL installation directory, configure the MySQL administrator account and other information. Normally, we select the default options to complete the installation.

3. Test MySQL

After the installation is complete, we need to test whether MySQL is working properly. You can find the MySQL command line tool under the start menu, enter the MySQL administrator account and password to enter the MySQL command line interface. Enter the "show databases;" command. If the existing databases in MySQL can be displayed normally, it means that the MySQL installation is successful.
