# PHP_Timer
|
||
|
|
|
||
|
|
Utility class for timing things, factored out of PHPUnit into a stand-alone component.
|
||
|
|
|
||
|
|
## Installation
|
||
|
|
|
||
|
|
You can use the [PEAR Installer](http://pear.php.net/manual/en/guide.users.commandline.cli.php) or [Composer](http://getcomposer.org/) to download and install this package as well as its dependencies.
|
||
|
|
|
||
|
|
### PEAR Installer
|
||
|
|
|
||
|
|
The following two commands (which you may have to run as `root`) are all that is required to install this package using the PEAR Installer:
|
||
|
|
|
||
|
|
pear config-set auto_discover 1
|
||
|
|
pear install pear.phpunit.de/PHP_Timer
|
||
|
|
|
||
|
|
### Composer
|
||
|
|
|
||
|
|
To add this package as a local, per-project dependency to your project, simply add a dependency on `phpunit/php-timer` to your project's `composer.json` file. Here is a minimal example of a `composer.json` file that just defines a dependency on PHP_Timer:
|
||
|
|
|
||
|
|
{
|
||
|
|
"require": {
|
||
|
|
"phpunit/php-timer": "*"
|
||
|
|
}
|
||
|
|
}
|
||
|
|
|
||
|
|
### Usage
|
||
|
|
|
||
|
|
#### Basic Timing
|
||
|
|
|
||
|
|
```php
|
||
|
|
PHP_Timer::start();
|
||
|
|
|
||
|
|
$timer->start();
|
||
|
|
|
||
|
|
// ...
|
||
|
|
|
||
|
|
$time = PHP_Timer::stop();
|
||
|
|
var_dump($time);
|
||
|
|
|
||
|
|
print PHP_Timer::secondsToTimeString($time);
|
||
|
|
```
|
||
|
|
|
||
|
|
The code above yields the output below:
|
||
|
|
|
||
|
|
double(1.0967254638672E-5)
|
||
|
|
0 ms
|
||
|
|
|
||
|
|
#### Resource Consumption Since PHP Startup
|
||
|
|
|
||
|
|
```php
|
||
|
|
print PHP_Timer::resourceUsage();
|
||
|
|
```
|
||
|
|
|
||
|
|
The code above yields the output below:
