floor-execution-time
====================

[](#floor-execution-time)

Floor a script's execution time.

This library will calculate a script's total execution time from `$_SERVER['REQUEST_TIME_FLOAT']` to *now* in milliseconds.

If the total execution time is *less than* the *floor*, it will sleep for the difference:

```
namespace Jstewmc\FloorExecutionTime;

// instantiate the service with a 500 millisecond floor
$service = new FloorExecutionTime(500);

// ... something that takes 100 milliseconds

$service();  // sleeps for 400 milliseconds
```

If the execution time is *greater than* the *floor*, it will not sleep:

```
namespace Jstewmc\FloorExecutionTime;

// instantiate the service with a 500 millisecond floor
$service = new FloorExecutionTime(500);

// ... something that takes 1,000 milliseconds

$service();  // sleeps for 0 milliseconds
```

Flooring execution time helps defend against *brute-force* and *timing* attacks. Scripts which are likely to be brute-forced should be slow. Scripts which are likely to be timing attacked should have a constant execution time. Some scripts should be both.

Dependencies
------------

[](#dependencies)

This library depends on the `REQUEST_TIME_FLOAT` [server variable](http://php.net/manual/en/reserved.variables.server.php). There is no guarantee that every web server will provide the `REQUEST_TIME_FLOAT` variable, however, most will. If the `REQUEST_TIME_FLOAT` server variable does not exist, this library will throw a `RuntimeException` on construction.
