====== Errorhandler class ======

Platform utilises a custom error handler, and a custom shutdown function that ensures that all semaphores are released on script end.

There are also some utility functions for debugging code.

===== Typechecking =====

To introduce semi-strict type checking on functions, the class introduces the ''checkParams()'' which takes a variable number of parameters, but always in pairs of two.

One pass a variable to the function and then a type name, and if the variable doesn't match the given type, then an error is triggered.

Example:

<code php>
/**
 * Display name and age of person.
 * @param string $name Name of person.
 * @param int $age Age of person.
 */
function displayNameAndAge($name, $age) {
  Errorhandler::checkParams($name, 'string', $age, 'int');
  echo $name.' - '.$age.' years.';
}
</code>

This will trigger an error if the ''$name'' and ''$age'' variable isn't of the correct types.

==== Types ====

The following types can be checked. If anything else is typed it is considered a name of a class.

|string|
|int|
|integer|
|float|
|array|
|resource|
|boolean|

integer and floats are checked based on content and not variable type, so a string containing a valid integer number will pass as a integer.
