How to install PHP in Windows and Linux systems

PHP is an open source, cross-platform scripting language that is widely used in the field of web development. Its installation is relatively simple, but it can be a bit confusing for beginners. This article will briefly introduce how to install PHP in Windows and Linux systems.

1. Install PHP in Windows system

1. Download the PHP installation package

Download the latest PHP installation package (php-7.4 from the PHP official website .1-Win32-vc15-x64.zip) and extract it to a directory on the local hard disk.

2. Configure the Path environment variable

In Computer Properties-Advanced System Settings-Environment Variables, find the Path variable and add the PHP installation path to its value.

3. Configuring PHP options

Find the php.ini-development file in the PHP installation directory and make a copy named php.ini. Open the php.ini file and modify some basic options, such as timezone and error_reporting. This will allow PHP to run better.

4. Test whether PHP is installed successfully

Enter the php-v command in the command line window. If the system can output the PHP version number normally, it means that PHP is installed successfully.

2. Install PHP in the Linux system

1. Execute the command to install PHP

In the Linux system, you can use apt-get, yum or other Package management tool to install PHP. The specific commands are as follows:

apt-get install php # Debian/Ubuntu system
yum install php # CentOS/RHEL system

2. Configure PHP options

In Linux systems, PHP configuration files are usually located in the /etc/php.ini or /etc/php.d directory. These files can be edited to modify PHP options.

3. Test whether PHP is installed successfully

Enter the php-v command on the command line. If the system can output the PHP version number normally, it means that PHP is installed successfully. In addition, you can also test whether PHP can run normally by writing a simple PHP script.

phpinfo();
?>

Access the script through the browser. If the PHP information can be output normally, it means that the PHP installation is successful.
