Prerequisites:

Before you begin, ensure you have the following:

• Basic knowledge of the command line
• SSH access to your server
• Sudo or root privileges
• PHP installed on your system

Estimated Time:

• Preparation: 5 minutes
• Installation: 20-30 minutes

Step-by-Step Installation Guide:

Step 1: Update Your System

Before installing any new packages, it’s essential to update your system to ensure all existing packages are up-to-date.

Ubuntu/Debian:

sudo apt update && sudo apt upgrade -y

CentOS/Fedora/Rocky Linux/Almalinux:

sudo dnf update -y

Step 2: Install PHP

Ensure PHP is installed on your system. If not, install it using the following commands:

Ubuntu/Debian:

sudo apt install php -y

CentOS/Fedora/Rocky Linux/Almalinux:

sudo dnf install php -y

Step 3: Install PHP Development Tools

To compile the Tokenizer extension, you need PHP development tools.

Ubuntu/Debian:

sudo apt install php-dev -y

CentOS/Fedora/Rocky Linux/Almalinux:

sudo dnf install php-devel -y

Step 4: Install the Tokenizer Extension

Most PHP installations come with the Tokenizer extension by default. However, if it’s not installed, you can add it manually.

Ubuntu/Debian:

sudo apt install php-tokenizer -y

CentOS/Fedora/Rocky Linux/Almalinux:

sudo dnf install php-tokenizer -y

Step 5: Verify the Installation

Check if the Tokenizer extension is enabled by running:

php -m | grep tokenizer

If ‘tokenizer’ appears in the output, the installation was successful.

Step 6: Edit PHP Configuration (if necessary)

If the Tokenizer extension is not enabled, you might need to edit your php.ini file.

Locate php.ini:

php --ini

Edit the file and ensure the following line is present and uncommented:

extension=tokenizer.so

Step 7: Restart Your Web Server

Restart your web server to apply the changes.

Apache:

sudo systemctl restart apache2

Nginx:

sudo systemctl restart nginx

Step 8: Verify with a PHP Info Page

Create a phpinfo.php file in your web root directory with the following content:

<?php phpinfo(); ?>

Access it via your web browser (e.g., http://your_server_ip/phpinfo.php) and look for the Tokenizer extension in the output.

Step 9: Clean Up

Remove the phpinfo.php file after verification to prevent security risks:

rm /path/to/phpinfo.php

Step 10: Keep Your System Updated

Regularly update your system and PHP packages to ensure security and performance.

sudo apt update && sudo apt upgrade -y sudo dnf update -y
