Re: [PHP-DEV] Reusing PHP string value pointers

Or use the overload extension in ZE1. The real question is why you really need/want to do this.

When a PHP string variable is changed via a PHP script, such as:

$foo = 'new value';

what happens to the `value.str.val' pointer internally? Is it possible

to

have the new value assigned to the same `value.str.val' pointer that

the

variable is currently using instead of having that pointer replaced by

a

pointer to the new value?

No, it's not possible (not in a reliable way anyway).

What about being able to register a callback function for variable
assignment? That way I can keep track of the pointer myself and copy the
new value to it when the variable value is changed in the PHP script.

Would

anybody else be interested in this functionality?
