A Comprehensive Guide to Installing PHP and Composer on Your Machine
PHP is one of the most popular server-side scripting languages, widely used for web development. Composer, on the other hand, is a dependency manager for PHP that simplifies managing libraries and packages in your projects. In this guide, we’ll walk through the steps to install PHP and Composer natively on your machine, highlighting the advantages of this approach over using bundled solutions like XAMPP or MAMP.
Prerequisites
Before we begin, make sure your system meets the following requirements:
- A working internet connection.
- Administrative privileges on your machine.
Step 1: Installing PHP
Installing PHP natively provides better performance and is a more professional approach, especially for production environments. Here’s how to do it across different operating systems:
On Windows
-
Download PHP:
- Visit the PHP Downloads page and download the latest version of PHP. Choose the appropriate version (Thread Safe) for your system.
-
Extract PHP:
- Extract the downloaded ZIP file to a directory of your choice, such as C:php.
-
Configure Environment Variables:
- Open the System Properties (Right-click on This PC > Properties > Advanced system settings).
- Click on “Environment Variables.”
- Under “System variables,” find the “Path” variable and click “Edit.”
- Add the path to your PHP directory (e.g., C:php).
-
Verify Installation:
- Open Command Prompt and type php -v. You should see the PHP version displayed.
On macOS
-
Install Homebrew (if not installed):
- Open Terminal and run the following command:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
-
Install PHP:
- Run the following command in Terminal:
brew install php
-
Verify Installation:
- After installation, check the PHP version with:
php -v
On Linux
-
Update Package Index:
- Open Terminal and run:
sudo apt update
-
Install PHP:
- For Ubuntu, run:
sudo apt install php
-
For CentOS, run:
sudo yum install php
-
Verify Installation:
- Check the PHP version:
php -v
Why Native Installation?
While tools like XAMPP and MAMP provide convenient ways to set up a development environment, they may introduce unnecessary overhead and complexity. Native installations are generally more efficient, allowing for better resource management, performance tuning, and a more granular understanding of the PHP environment.
Step 2: Installing Composer
Composer can be installed globally, allowing you to manage dependencies for all your PHP projects.
On Windows
-
Download Composer Installer:
- Visit the Composer Download page and download the Composer-Setup.exe file.
-
Run the Installer:
- Execute the downloaded file and follow the instructions. It will automatically detect your PHP installation.
-
Verify Installation:
- Open Command Prompt and type:
composer -V
On macOS and Linux
-
Download Composer:
- Open Terminal and run the following command:
curl -sS https://getcomposer.org/installer | php
-
Move Composer to a Global Directory:
- After the download, move Composer to a directory in your PATH:
sudo mv composer.phar /usr/local/bin/composer
-
Verify Installation:
- Check the Composer version:
composer -V
Conclusion
You have successfully installed PHP and Composer on your machine! By opting for native installations, you ensure better performance and a more professional setup. Composer will allow you to easily manage libraries and dependencies, keeping your projects organized and up-to-date.

Absolute session timeout starts at the time of session creation, while an idle session timeout starts at the time of user's no operation. Absolute session timeout is suitable for scenarios where strict control of the session life cycle is required, such as financial applications; idle session timeout is suitable for applications that want users to keep their session active for a long time, such as social media.

The server session failure can be solved through the following steps: 1. Check the server configuration to ensure that the session is set correctly. 2. Verify client cookies, confirm that the browser supports it and send it correctly. 3. Check session storage services, such as Redis, to ensure that they are running normally. 4. Review the application code to ensure the correct session logic. Through these steps, conversation problems can be effectively diagnosed and repaired and user experience can be improved.

Setting the httponly flag is crucial for session cookies because it can effectively prevent XSS attacks and protect user session information. Specifically, 1) the httponly flag prevents JavaScript from accessing cookies, 2) the flag can be set through setcookies and make_response in PHP and Flask, 3) Although it cannot be prevented from all attacks, it should be part of the overall security policy.

Session regeneration refers to generating a new session ID and invalidating the old ID when the user performs sensitive operations in case of session fixed attacks. The implementation steps include: 1. Detect sensitive operations, 2. Generate new session ID, 3. Destroy old session ID, 4. Update user-side session information.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
