Re: [PHP-DEV] AUTOLOAD in PHP
Hi Thanks for you to point me such coding style. I had looked in to unserialize() callback mechanism, you know, it is now disabled in 4.1.2 (look at ext/standard/incomplete_class.c ) In manual also there is nothing about callback function and all, anyway the link you showed me has a seperate Note about that. I think to pass the undef_function_name as first argument, could you point me any code similar to this.

[PHP-DEV] AUTOLOAD in PHP
Hi,
As I told in my Previous Post that I have added a feauture in PHP
which is similar to AUTOLOAD feauture in Perl Modules.
I had sent a unified diff output along with this.
According to that if a user tried to call a undefined function,
PHP Zend Engine would search for a function named '__autoload' in current
scope, if it finds one, it would set the global variable
$php_undef_func_name
with name of the called function and call the __autoload() function with
passed arguments.
Its working fine for me. If it seems to be good, we could discuss
on this.

Re: [PHP-DEV] AUTOLOAD in PHP
Hi Chris I Intially thought about passing function name as first argument only, but I don't know whether I done it correctly or not, Its not recognizing the argument that I pushed in to argument stack. If you help me in how to do this, it would be really helpful to me. After some two days of trying that, I switched over to this method of passing function name. overload() -- When I searched for AUTOLOAD requierment in PHP, I came across overload() function, but its not working for me, even the property overloading, Its seems to be not recognizing __get or __set method. If anything needs to be done for this, please tell me.

Otherwise, this looks like some interesting code - I'm looking forward to the overload() extension to do similar things with object methods and properties.
