PHP typecasting

by 
(int)$value

saves one function call compares to intval($value) and settype($value, 'int').

And (int)$value is clean enough, so I prefer this way.

When you need to use intval($value) is that when you need to use the specified base for the conversion (the default is base 10). intval accepts a second parameter for the base for the conversion.
