CLI Session Helper for PHP
A lightweight utility class to manage and inspect CLI session environments in PHP.  
Designed for cross-platform compatibility (Linux, macOS, Windows) with focus on stream handling, session identification, terminal capability detection, and environmental diagnostics.
> No external dependencies. Built for PHP 7+
Features
- 
Detects and resolves `STDIN`, `STDOUT`, `STDERR` in CLI environments
- 
Handles platform-specific stream opening safely
- 
Retrieves:
- Terminal size (height and width)
- Current user (`whoami`)
- MAC address
- OS and system model
- Shell and terminal name
- 
Detects:
- ANSI and color support
- Platform type (Windows, macOS, Linux, cloud)
- 
Generates a unique system identifier for CLI sessions
- 
Silently handles errors using proper fallbacks
Installation
Install via Composer PHP package manager.
composer require peterujah/php-cli-session
Usage
Initialize CLI streams
use Peterujah\Cli\System\Session;
Session::init(); // Optional if constructor is called
Start PHP session with CLI-safe ID
$sessionId = Session::getSystemId();
session_id($sessionId);
session_start();
See working example CLI Demos
Examples
Get CLI terminal info
$info = Session::getSystemInfo();
foreach ($info as $item) {
    echo $item['Name'] . ': ' . $item['Value'] . PHP_EOL;
}
Detect color and ANSI support
if (Session::isColorSupported()) {
    echo "? Color output is supported." . PHP_EOL;
}
if (Session::isAnsiSupported()) {
    echo "? ANSI escape sequences are supported." . PHP_EOL;
}
Detect terminal dimensions
$width = Session::getWidth();
$height = Session::getHeight();
echo "Terminal Size: {$width} x {$height}" . PHP_EOL;
