Lightweight PHP time measurement
================================

[](#lightweight-php-time-measurement)

Useful for debugging slow scripts and optimizing frameworks.

- Simple **start** / **stop** stopwatch
- Supports **nested** measurements
- **Aggregated** measurements for **repeating** functions
- Plain text **report**

Exception handling
------------------

[](#exception-handling)

The Stopwatch will throw an exception on any anomaly. However, by default these exceptions are silently ignored.

In order to set a custom handler use:

```
StopwatchException::setExceptionHandler(StopwatchExceptionHandling $handler);
```

For complete list of exceptions, see `/src/Exception` directory.

API
---

[](#api)

#### Simple usage

[](#simple-usage)

Use the pair of methods `Stopwatch::start(string $name)` and `Stopwatch::stop(string $name)` to measure elapsed time.
The `string $name` is used to name and identify the measurement and it must match across the two methods.

`Stopwatch::stop(string $name)` returns an instance `Measurement`, which holds the information about the measurement.

Example:

```
Stopwatch::start('Init');
// ...
$measurement = Stopwatch::stop('Init'); // Returns an instance of Measurement

// Available options
$measurement->getStart();    // The start time of the measurement, in milliseconds
$measurement->getEnd();      // The end time of the measurement in milliseconds
$measurement->getTime();     // The total time elapsed in milliseconds
```

#### Nested

[](#nested)

Nested measurements allow you to get more details where the time is spent, but also to easily know the total time spent. Level of nesting is not limited.

Example:

```
Stopwatch::start('Total');
    // ...
    Stopwatch::start('Init');
        // ...
    Stopwatch::stop('Init');

    Stopwatch::start('Database');
        Stopwatch::start('Connection');
            // ...
        Stopwatch::stop('Connection');

        Stopwatch::start('Read');
            // ...
            Stopwatch::start('Cache');
            	// ...
            Stopwatch::stop('Cache');
        Stopwatch::stop('Read');
    Stopwatch::stop('Database');
$measurement = Stopwatch::stop('Total');

// The total time elapsed in 'Total', in milliseconds
$measurement->getTime();

// The list of direct children measurements ('Database' and 'Rendering'), with same API as this measurement
$subMeasurements = $measurement->getChildren();
```

#### Aggregated

[](#aggregated)

If a certain function is called multiple times, measure the total time.

```
$loops = 10;
while ($loops--) {
	Stopwatch::startAggregate('loop');
		// ...
	Stopwatch::pauseAggregate('loop');
}

// Get the instance of ```
AggregateMeasurment
```
$aggregateMeasurement = Stopwatch::getAggregatedMeasurements()['loop'];

$aggregateMeasurement->getTotal()	// The total elapsed time, in milliseconds
$aggregateMeasurement->getCount()	// The number of loops
```

#### Print summary

[](#print-summary)

Print the summary of all measurements as plain text: `$measurement->report()`.

```

```

From the nested example above, will produce:

```
Total: 100
├───Init: 9
└───Database: 91
	├───Connection: 76
	└───Read: 15
		└───Cache: 3
```

TODO
----

[](#todo)

1. Tests.
2. Improve the print summary.
