how to edit php source

[raja_tlr]

hi,
I've downloaded php source which has folders like build, ext ,etc.. . Now I want to view the actual source of functions like mysql_fetch_row() etc.. Where can i find those definitions.

Also, I'd like to edit the code and use the edited code to compile my application programs. How to do this. Thanks.

You can edit the code with any C editor, can't you?

PHP is not a compiled language. The source code is interpreted on run-time and the source code is always available in its original state, except in those cases when it's encoded. If you can't edit the source code, it is encoded. And if it is encoded, that means the developers of the program didn't want you to edit it in first place.

Sounds more like he wants to view (and edit) the PHP language source code, and not a scripts code.

If you want to make changes to it (and somehow think this is a good idea) then all I can do is strongly discourage.

Oh, indeed as I read the post second time. That's quixotic alright. Try writing your own extensions instead, that would at least make some sense.

mysql would be in ext/mysql or ext/mysqli

mysql_fetch_row for example is in ext/mysqli/mysqli_api.c

PHP_FUNCTION(mysqli_fetch_row)

You will need to learn about php's core first
