# Debugging
|
|
|
|
SilverStripe can be a large and complex framework to debug, but there are ways to make debugging less painful. In this
|
|
guide we show the basics on defining the correct [Environment Type](environment_types) for your application and other
|
|
built-in helpers for dealing with application errors.

|
## Performance
|
|
|
|
See the [Profiling](../performance/profiling) documentation for more information on profiling SilverStripe to track down
|
|
bottle-necks and identify slow moving parts of your application chain.
|
|
|
|
## Debugging Utilities
|
|
|
|
The [Debug](api:SilverStripe\Dev\Debug) class contains a number of static utility methods for more advanced debugging.
|
|
|
|
```php
|
|
use SilverStripe\Dev\Debug;
|
|
use SilverStripe\Dev\Backtrace;
|
|
|
|
Debug::show($myVariable);
|
|
// similar to print_r($myVariable) but shows it in a more useful format.
|
|
|
|
Debug::message("Wow, that's great");
|
|
// prints a short debugging message.
|
|
|
|
Backtrace::backtrace();
|
|
// prints a calls-stack
|
|
```
