Subject: casting php5 objects
From: curt@php.net (Curt Zirzow)


In reference to bug #29029 (http://bugs.php.net/29029):

Current casting object behaviour:
  int      - not able to cast
  dobule   - notice thrown, returns 1.0
  null     - will return null
  bool     - returns 1 (from result of double)
  string   - user __toString() if applicable or 'Object'

Beyond the ridiculous idea of adding a __toInt(), __toDouble()..
etc.  What about the idea that casting int so that it returns the
id of the object, and the double value returns the int casted as a
double value.  So:

  $o1 = new stdClass();
  $o2 = new stdClass();
  $o3 = new stdClass();

  var_dump((int) $o1);    /* 1   */
  var_dump((double) $o2); /* 2.0 */
  var_dump((int) $o3);    /* 3   */

Otherwise, I'll just move this over as a documentation problem.

First, let me assure you that this is not one of those shady pyramid schemes
you've been hearing about.  No, sir.  Our model is the trapezoid!
