How to download and install php7 (tutorial sharing)

With the development of Internet technology, computer programming languages ​​have also been continuously developed and updated. As a programming language widely used in the field of web development, PHP has experienced multiple version updates over the years, and the latest version of PHP7 has greatly improved its performance and stability. In order to better apply the PHP programming language, this article will introduce the download and installation tutorial of PHP7 for beginners' reference.

1. Download PHP7

First, we need to go to the official website to download the PHP7 installation package. The official website is: https://www.php.net/downloads.php

Find the "Download" button on the webpage and click it to enter the download page. Find the download link for the PHP7 version on the page, and select the installation package suitable for your system version and bit number to download.

2. Install PHP7

After completing the download, double-click the installation package and follow the prompts to complete the installation. If the installation process prompts you to install related components, you can select the corresponding components to install.

Note: Before installing PHP7, you need to install the corresponding web server software, such as Apache, Nginx, etc. This tutorial will not go into details about the installation and configuration process of the web server.

3. Configure PHP7

After successful installation, PHP7 needs to be configured with the web server to run normally. Below we take the Apache server as an example to introduce how to configure PHP7.

First, find the php.ini file in the PHP installation path and open it with a text editor.

You need to modify the following options:

extension_dir = "ext"

Modify extension_dir to the actual extension path

; extension=php_openssl.dll Uncomment

; extension=php_pdo_mysql.dll Uncomment

`; env[PATH] = /usr/local/bin:/usr/bin:/bin
env[MYSQL_HOME] = /usr/local/mysql
extension_dir = "/usr/lib/php/extensions/no-debug-non-zts-20121212"`

Modify extension_dir to the actual extension path

After completing the above modifications, save the file and exit. Next, we need to associate the PHP module with the Apache server.

Find the httpd.conf file of the Apache server, which is generally located in the conf folder under the Apache installation directory.

Find the following lines of code in the file:

LoadModule php5_module "C:/php/php5apache2_4.dll"

Change the value of "php5_module" to the name of the actual php module, and change the path of the dll file to the actual path, for example:

LoadModule php7_module "C:/php/php7apache2_4.dll"

After saving the changes, just restart the Web server according to the Web server restart process.

4. Test PHP7

After the configuration is successful, let’s test whether PHP7 is working properly. When installing Apache, a simple web service test page is often installed. Enter the address in the browser: http://localhost. If the page displays normally, it means that the Apache server is installed successfully. Next, let’s do a PHP7 test:

Create a new test.php file in any text editor and enter the following content:

<?php   
    phpinfo();  
?>

Save the file and upload it to the Apache of the web server The root directory is sufficient (usually /var/www/html or htdocs). Then enter the viewing directory by visiting http://localhost/test.php to see if the information output by the phpinfo() function can be accessed normally.
