In other words where is the _COOKIE array created and populated?

I suggest talking to folks on the PHP Internals mailing list if you're interested in exploring or modifying the PHP source: http://news.php.net/php.internals – leepowers Aug 31 '10 at 04:05

The $_COOKIE variable doesn't use JIT (just-in-time initialization), so it's always accessible by reading the global variables table EG(symbol_table):
zval **cookie_var;
if (zend_hash_find(&EG(symbol_table), "_COOKIE", sizeof("_COOKIE"),
(void**)&cookie_var) == SUCCESS) {
/* do something with cookie_var */
} else {
/* handle error; shouldn't happen */
}

Where would I pass the name 'views'?? is the value of **(cookie_var) = 'views'? – Karthick Aug 31 '10 at 04:18

@Kar You'd have to do another hash lookup on the array `cookie_var`: `zend_hash_find(Z_ARRVAL_PP(cookie_var), "views", sizeof("views"), (void**)&my_var)` – Artefacto Aug 31 '10 at 04:24

ok.. now the zval char mismatch error occurs.. I am new to this extension writing. So can u help me? I know that the variable name is 'views' and it is going to be constant.. So I dont have to get that from the user.. – Karthick Aug 31 '10 at 04:29

@Kar I recommend you start by reading some of the resources [here](http://stackoverflow.com/questions/2970682/how-to-develop-c-extentions-for-php-apps/2970709#2970709). – Artefacto Aug 31 '10 at 04:43

Yes.. I ll do that.. bUt I need it kind of very urgent. I just want to read 'views' variable set by the user in the extension. Can u give me the working snippet for that? – Karthick Aug 31 '10 at 04:46

I don want the extension code.. as i am just adding an api.. So would be great if u could help me with the snippet.. – Karthick Aug 31 '10 at 05:01

Cookie info comes as part of your http headers (that the browser sends). PHP makes it easier to access them by parsing it out in to a neat array and putting it in _COOKIE. You'll have to do it in C.
