README

A Composer package for PHP that adds a seriously simple progress tracker, with a focus on estimating completion time.

<?php

use Othyn\TimeRemaining\TimeRemaining;

$timeRemaining = new TimeRemaining(100);
sleep(30); // Simulate some work being done.

$formattedProgress = $timeRemaining->getFormattedProgress(50);
echo $formattedProgress; // Output: [50% - 50 / 100][~ 0h 0m 30s remaining]

The package is available on Packagist as othyn/php-time-remaining.

Installation

Hop into your project that you wish to install it in and run the following Composer command to grab the latest version:

composer require othyn/php-time-remaining

Usage

For more comprehensive usage examples, you can view the test suite. However I'll show some basic usage examples below.

Initialisation

To start using the TimeRemaining package, initialise it with the total number of items required:

<?php

require 'vendor/autoload.php';

use Othyn\TimeRemaining\TimeRemaining;

$totalItems = 100;
$timeRemaining = new TimeRemaining($totalItems);

You can also later update the total amount of items if you cannot define it at the point of initialisation:

<?php

require 'vendor/autoload.php';

use Othyn\TimeRemaining\TimeRemaining;

$timeRemaining = new TimeRemaining();

// Code that fetches total items as $totalItems

$timeRemaining->setTotalItems($totalItems);

Formatting the Output

To get a formatted string showing the progress and remaining time:

<?php

$formattedProgress = $timeRemaining->getFormattedProgress($currentItem);
echo $formattedProgress; // Output: [50% - 50 / 100][~ 0h 0m 30s remaining]

You can also customise the format:

<?php

$customFormat = '[%d%% - %d / %d items][~ %dh %dm %ds left]';
$formattedProgressCustom = $timeRemaining->getFormattedProgress($currentItem, $customFormat);
echo $formattedProgressCustom; // Output: [50% - 50 / 100 items][~ 0h 0m 30s left]

Getting Elapsed Time

To get the elapsed time since the initialisation:

<?php

$elapsedTime = $timeRemaining->getElapsedTime();
echo "Elapsed time: {$elapsedTime} seconds\n";

Getting Progress

To get the progress based on the current item:

<?php

$currentItem = 50;
$progress = $timeRemaining->getPercentageProgress($currentItem);
echo "Progress: {$progress}%\n";

Getting Estimated Total Time

To get the estimated total time for the process:

<?php

$estimatedTotalTime = $timeRemaining->getEstimatedTotalTime($currentItem);
echo "Estimated total time: {$estimatedTotalTime} seconds\n";

Getting Remaining Time

To get the remaining time for the process:

<?php

$remainingTime = $timeRemaining->getRemainingTime($currentItem);
echo "Remaining time: {$remainingTime} seconds\n";

Development

Most development processes are wrapped up in an easy to use Docker container.

Enforcing Style

The projects .php-cs-fixer.dist.php config contains the rules that this repo conforms to and will run against the ./src and ./tests directory.

For remote style enforcement there is a GitHub Action configured to automatically run phpcsfixer.

For local style enforcement there is a composer script composer style configured to run phpcsfixer.

Testing

For remote testing there is a GitHub Action setup to automatically run the test suite on the main branch or and PR branches.

For local testing there is a Docker container that is pre-built that contains an Alpine CLI release of PHP + PHPUnit + xdebug. This is setup to test the project and can be setup via the following:

composer docker-build

This should trigger Docker Compose to build the image. You can then up the container via the following:

composer docker-up

There are tests for all code written, in which can be run via:

# PHPUnit with code coverage report
composer test

# PHPUnit with code coverage report, using local phpunit and xdebug
composer test-local

In those tests, there are Feature tests for a production ready implementation of the package. There are no Unit tests at present.

You can also easily open a shell in the testing container by using the command:

composer docker-shell

othyn / php-time-remaining
