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;
use Utopia\Command;

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

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

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

$output = '';
$stderr = '';
$command = new Command(PHP_BINARY)
    ->option('-r', 'echo "Hello";');

$exitCode = Console::execute($command, '', $output, $stderr, 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 stdout and stderr into the referenced output variables. Pass a timeout (in seconds) to stop long-running processes and an optional progress callback to stream intermediate output. Prefer Utopia\Command or argv arrays when you want structured command building.

$command = new Command(PHP_BINARY)
    ->option('-r', 'fwrite(STDOUT, "success\\n");');

$output = '';
$input = '';
$stderr = '';
$exitCode = Console::execute($command, $input, $output, $stderr, 3);

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

Build Commands

Use flag() for switches without a value, option() for keys that take a value, and argument() for positional arguments.

$command = new Command('tar')
    ->flag('-cz')
    ->option('-f', 'archive.tar.gz')
    ->option('-C', '/tmp/project')
    ->argument('.');

Compose Commands

Use the static helpers when you need shell operators such as pipes, &&, ||, grouping, or redirects.

$pipeline = Command::pipe(
    new Command('ps')->flag('-ef'),
    new Command('grep')->argument('php-fpm'),
    new Command('wc')->flag('-l'),
);

$deploy = Command::and(
    Command::group(
        Command::or(
            new Command('build'),
            new Command('build:fallback'),
        )
    ),
    new Command('publish'),
);

$logs = Command::appendStdout(
    Command::pipe(
        new Command('cat')->argument('app.log'),
        new Command('grep')->argument('ERROR'),
    ),
    'errors.log',
);

Plain commands execute in argv mode. Composed, grouped, and redirected commands execute through shell syntax.

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 8.0 or later. We recommend using the latest PHP version whenever possible.
