Implicit Type Conversion for PHP Classes?

Question

Is there a way to tell the php complier that I want a specific implicit conversion from one type to another?

A simple example:

class Integer
{
  public $         


        

Answer 1

Are you asking how to type cast? You can do:

$ php -r 'var_dump("333");'
string(3) "333"
$ php -r 'var_dump((int)"333");'
int(333)

Otherwise PHP is weakly typed, so in general you don't need to do it. It's implied by the language. Eg. if a function takes a numeric argument, then that number can be string, integer or float all the same; The value is converted if needed. That's why you can for example echo 33 without an error.
