How BG(last_repsonse_headers) gets its value in PHP ?

[HeenaBansal20]

Description

HI ,

I apologize for raising a bug issue though It is a question..
Since I don't find the Issue type:Question , I need to submit as a Bug.
May be you can add one more isse type as questions/general category to handle these kind of requests.


On the side note:

I am looking the implementation of the function http_get_last_response_headers and came across global variable BG(last_repsonse_heaqders)
However I would like to know how this val gets populated and gets its value. I cannot see any much reference for this zval literal in php src code.
I am basically looking how php captures the response headers from http stream.
Thanks

PHP Version

PHP 8.3

Operating System

Ubuntu 22.0.0

Note sure if you meant last_http_headers in fact ? If that s the case, you can have a look at php_stream_url_wrap_http for starter.

@devnexen for the prompt reply , yes, I am looking for this var BG(last_http_headers), where this var gets value ?

I think I've seen your name before, if I remember correctly you re doing php extension(s) right ? As mentioned earlier, please have a look at php_stream_url_wrap_http (or even more directly php_stream_url_wrap_http_ex) you ll see how values are created, sanitised ... Cheers !

@cmb69 , Thanks for the info. I looked in to the code for php_stream_url_wrap_http and this seems to be specific to php streams functions , However I am looking for something similar for curl.

By using curl_getinfo , I can get request headers but , is there any way I can get response headers from curl handle ?
