PHP: casting to a dynamically determined type

Question

I'd like do something like this:

$type = "int"; $casted = ($type)$value; 

This doesn't work. But is there some other way to cast to a dynamically determined type?

Thanks

Use the settype() function.

Example:

$type = 'int'; $var = '20'; settype($var, $type); var_dump($var);
