How to install and configure the environment after downloading the php source code

PHP is an open source programming language that is very popular, especially in the field of website development. In the process of learning PHP, it is very necessary to understand how to install the PHP source code, because only by correctly installing the source code can PHP development be carried out smoothly. This article will introduce the installation path of PHP source code.

1. Download the PHP source code

First, you need to download the PHP source code compressed package from the PHP official website. You need to choose the version suitable for your operating system. The download address of the installation package is: http://www.php.net/downloads.php. Note that if your server is on the intranet, you need to use a dedicated terminal tool to download the PHP source code, otherwise the download speed will be very slow.

2. Unzip

After the download is complete, you need to unzip the PHP source code file. During the unzipping process, you need to select a suitable folder, which will store the PHP source code. After unzipping, you will find that there are many files from various versions and stages of development, and that these files differ between versions.

3. Configure the environment

Before installing PHP, you need to configure the environment first. Depending on your server type and operating system, there are different ways to configure it. If you are using a Linux or Unix system, you need to open a terminal window and enter the following command:

sudo apt-get update
sudo apt-get install apache2
sudo apt-get install php

This will install PHP and all its components. If you are using a Windows operating system, you need to download the Apache server, and then download PHP and its extensions.

4. Install PHP

After configuring the environment, you can run the following operations to install the PHP source code:

cd php-7.x.x
./configure --with-apxs2=/usr/local/apache2/bin/apxs --with-mysql=/usr/local/mysql --enable-mbstring --prefix=/usr/local/php

The "/usr /local/apache2/bin/apxs" and "/usr/local/mysql" need to be set according to the server path you use. After executing the above command, you need to run the following command:

make
make install

These commands will compile and install the PHP source code. Depending on your computer configuration and network speed, this process may take some time.

5. Verify installation

When the installation is completed, you need to verify whether PHP is installed correctly. You can enter the following code in a PHP file:

<?php phpinfo(); ?>

Save this code and access this file. If it can run normally, congratulations, PHP is successfully installed! At this point, you can start running PHP programs and develop them.

In summary, installing PHP source code requires the following steps: download, decompress, configure the environment, install, and verify the installation. Once you master these methods, you can easily install PHP source code.
