How to compile and install PHP in Linux system

PHP is a popular server-side scripting language that many developers choose to use to build web applications. For those who wish to control their PHP installation, a compile installation is the best option as it allows you to choose the different directories in which you want to install PHP. This article will introduce how to compile and install PHP in a Linux system and guide you to install it in the required directory.

Install the compilation environment

Before compiling and installing PHP, first make sure that some necessary compilation environments have been installed in the system. This includes the GNU Compiler Collection (GCC) and the make tool. Install on Ubuntu using the following command:

sudo apt-get update
sudo apt-get install build-essential

For other Linux distributions, you will need to use an appropriate package manager.

Download and decompress the PHP source code

The source code of PHP can be downloaded from its official website (http://php.net/downloads.php). Select the latest version of the source code and download it to your computer. Next, unzip the downloaded file using the following command:

tar -zxvf php-x.x.x.tar.gz

After unzipping, you will get a directory named "php-x.x.x", where "x.x.x" is the PHP version number. Enter this directory to continue.

Configuring PHP options

Before compiling PHP, you need to configure some options for it. This will ensure that PHP is compiled with the required features and extensions. Use the following command to configure PHP:

./configure --prefix=/path/to/install/dir [options]

In this command, "/path/to/install/dir" is the directory where you wish to install PHP. You can change this option as needed. It is also possible to add other options such as "--with-mysql" to support MySQL databases.

Compile PHP

After completing the configuration, you need to compile PHP. Use the following command to compile:

make

The process may take a few minutes to complete.

Install PHP

After compilation is completed, you can use the following command to install PHP:

sudo make install

This command will install the PHP binary files and other related files into the directory you specify. After this, you can check if PHP has been installed correctly by running the following command:

/path/to/install/dir/bin/php -v

This command will display the installed PHP version number. If it's the version you expected, the installation is complete!

Conclusion

Compiling and installing PHP provides more flexibility than using a binary package because it allows you to install PHP in the desired directory. In this article, we introduce how to compile and install PHP in a Linux system and guide you how to install it into a custom directory. If you followed the steps above, you will be able to install multiple PHP versions in different directories and switch them as needed.
