The official image from streamline does not currently work for the arm64 platform. As a temporary measure, the source code and docker build scripts have been lifted from the official images and are used to build locally. Some additional modifications are made to reduce overall image size, these are documented in docker/README.md
phpunit/php-timer
Utility class for timing things, factored out of PHPUnit into a stand-alone component.
Installation
You can add this library as a local, per-project dependency to your project using Composer:
composer require phpunit/php-timer
If you only need this library during development, for instance to run your project's test suite, then you should add it as a development-time dependency:
composer require --dev phpunit/php-timer
Usage
Basic Timing
require __DIR__ . '/vendor/autoload.php';
use SebastianBergmann\Timer\Timer;
$timer = new Timer;
$timer->start();
foreach (\range(0, 100000) as $i) {
// ...
}
$duration = $timer->stop();
var_dump(get_class($duration));
var_dump($duration->asString());
var_dump($duration->asSeconds());
var_dump($duration->asMilliseconds());
var_dump($duration->asMicroseconds());
var_dump($duration->asNanoseconds());
The code above yields the output below:
string(32) "SebastianBergmann\Timer\Duration"
string(9) "00:00.002"
float(0.002851062)
float(2.851062)
float(2851.062)
int(2851062)
Resource Consumption
Explicit duration
require __DIR__ . '/vendor/autoload.php';
use SebastianBergmann\Timer\ResourceUsageFormatter;
use SebastianBergmann\Timer\Timer;
$timer = new Timer;
$timer->start();
foreach (\range(0, 100000) as $i) {
// ...
}
print (new ResourceUsageFormatter)->resourceUsage($timer->stop());
The code above yields the output below:
Time: 00:00.002, Memory: 6.00 MB
Duration since PHP Startup (using unreliable $_SERVER['REQUEST_TIME_FLOAT'])
require __DIR__ . '/vendor/autoload.php';
use SebastianBergmann\Timer\ResourceUsageFormatter;
foreach (\range(0, 100000) as $i) {
// ...
}
print (new ResourceUsageFormatter)->resourceUsageSinceStartOfRequest();
The code above yields the output below:
Time: 00:00.002, Memory: 6.00 MB
