Step 1: Download the source code
First, you need to download the PHP source code from the PHP official website. You can choose the latest stable version or an older version. On the download page, you can see options for different versions. Select the version for your operating system and download the source code archive. After unzipping the file, go to the unzipped directory.
Step 2: Install compilation tools and dependencies
Before you start compiling and installing PHP extensions, you must first install certain key compilation tools and dependencies. In Ubuntu, these dependencies can be installed using the following command:
sudo apt-get install build-essential sudo apt-get install libxml2-dev libssl-dev libbz2-dev libcurl4-openssl-dev libjpeg-dev libpng-dev libfreetype6-dev libmcrypt-dev libreadline-dev
In other Linux distributions, install these packages using the corresponding package manager.
Step 3: Compile PHP
Enter the source code directory and use the following command to compile PHP:
./configure --prefix=/usr/local/php --with-pdo-mysql
The above command specifies the installation directory of PHP and compile option --with-pdo-mysql to support MySQL database connections. After executing the above command, the Makefile will be generated. Run the following command to compile PHP:
make
This process may take a few minutes or longer, depending on the performance of your system. If there are no errors, you can execute the following command to install PHP:
sudo make install
Step 4: Open the php.ini file
Enabling the PDO-MYSQL extension requires editing php.ini file, this needs to be done after installing PHP. In Ubuntu, this file can be found at:
/etc/php/7.2/apache2/php.ini
In other Linux distributions, the location may vary, but it can usually be found in the "/etc/php" directory. Add the following code to the php.ini file, which can be achieved by searching for the keyword "extension=":
extension=pdo_mysql.so
This code will enable the PDO-MYSQL database extension. Save the file and exit the editor.
Step 5: Restart the web server
Finally, you need to restart the web server for the changes to take effect. In Ubuntu, use the following command to restart the Apache server:
sudo service apache2 restart
In other Linux distributions, use the corresponding system prompts to restart the web server.
