Is there a generic way (for extensions, of course) to override the operators
between objects implementing __toString()?
See, I have two objects:
$o1 = new QString("php");
$o2 = new QString("-internals");
Now I could do:
$result = $o1->operator+=($o2);
better would be:
$result = $o1 .= $o2;
should result in "php-internals"
Can I modify the object structure in any way to register my own operator
functions which can be called by the engines execution unit? I found only
hard-wired implementations of that if I looked into the 'zend execute' code
or maybe I'm wrong. Ideally there would be something like a pointer in every
zval which points to a struct or table of 'operator-function pointers'. In
this case I could override it and point to another operator-function pointer
table. Ok, I can dream ;-)
In the current implementation (php 5.1) a function zend_make_printable' is
called, and there zend_std_cast_object_tostring. This means that the objects
__toString() result will be passed to the underlying system, and there is no
unicode support yet. What I would prefer is calling overidden operators
before __toString() is called.
Am I wrong? Can anybody help me please?
Thanks,
Thomas
