## Installation
|
|
8
|
|
|

|
You can add this library as a local, per-project dependency to your project using [Composer](https://getcomposer.org/):
|
|
10
|
|
|
11
|
composer require phpunit/php-timer
|
|
12
|
|
|
13
|
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:
|
|
14
|
|
|
15
|
composer require --dev phpunit/php-timer
|
|
16
|
|

### Basic Timing
|
|
20
|
|
|
21
|
```php
|
|
22
|
PHP_Timer::start();
|
|
23
|
|
|
24
|
// ...
|
|
25
|
|
|
26
|
$time = PHP_Timer::stop();
|
|
27
|
var_dump($time);
|
|
28
|
|
|
29
|
print PHP_Timer::secondsToTimeString($time);
|
|
30
|
```
|
|
31
|
|
|
32
|
The code above yields the output below:
|
