Utopia Console

Small collection of helpers for working with PHP command line applications. The Console class focuses on everyday needs such as logging, prompting users for input, executing external commands, and building long-running daemons.

Installation

Install using Composer:

composer require utopia-php/console

Usage

<?php
require_once __DIR__.'/vendor/autoload.php';

use Utopia\Console;

Console::success('Ready to work!');

$answer = Console::confirm('Continue? [y/N]');

if ($answer !== 'y') {
    Console::warning('Aborting...');
    Console::exit(1);
}

$output = '';
$exitCode = Console::execute('php -r "echo \"Hello\";"', '', $output, 3);

Console::log("Command returned {$exitCode} with: {$output}");

Log Messages

Console::log('Plain log');        // stdout
Console::success('Green log');    // stdout
Console::info('Blue log');        // stdout
Console::warning('Yellow log');   // stderr
Console::error('Red log');        // stderr

Execute Commands

Console::execute() returns the exit code and writes the combined stdout/stderr output into the third argument. Pass a timeout (in seconds) to stop long-running processes and an optional progress callback to stream intermediate output.

$output = '';
$input = '';
$exitCode = Console::execute('>&1 echo "success"', $input, $output, 3);

echo $exitCode;  // 0
echo $output;    // "success\n"

Create a Daemon

Use Console::loop() to build daemons without tight loops. The helper sleeps between iterations and periodically triggers garbage collection.

<?php

use Utopia\Console;

Console::loop(function () {
    echo "Hello World\n";
}, 1); // 1 second

System Requirements

Utopia Console requires PHP 7.4 or later. We recommend using the latest PHP version whenever possible.
