README

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;

Methods Overview

Method	Description
`init()`	Initializes CLI stream resources (`STDIN`, `STDOUT`, etc.)
`getSystemId()`	Returns a unique, hash-based identifier for the current system
`getSystemInfo()`	Returns structured system diagnostics
`getTerminalName()`	Returns terminal name (`tty`, PowerShell, etc.)
`getMacAddress()`	Retrieves system MAC address
`getPid()`	Gets the parent process ID
`whoami()`	Gets the current user executing the script
`isColorSupported()`	Checks if terminal supports color output
`isAnsiSupported()`	Checks if terminal supports ANSI escape codes
`getWidth()` / `getHeight()`	Gets terminal width and height
`isPlatform($os)`	Checks for OS platform or cloud environment

Platform Compatibility

OS	Status
Linux	✅ Tested
macOS	✅ Tested
Windows	✅ Tested
BSD/Unix	⚠️ Partial support
Docker	✅ Supported (if `tput` or `stty` available)
