I need to understand better the ArrayAccess interface. The documentation points to http://php.net/manual/en/class.arrayaccess.php but I would like to see the source code on my own for learning purposes. Where can I find it? On my debian there has to be this class.arrayaccess.php file somewhere right? in /etc/php/7.1 folder there are only .ini files. On the official repo https://github.com/php I have no clue where it is. Am I missing something? Thank you for your help

  • PHP is written in C, not in PHP. Can you obtain the information you want from C source code? – Álvaro González May 31 '17 at 11:49
  • You have the code in the documentation, there is no mistery...Do you want to learn the PHP core or just PHP? – ka_lin May 31 '17 at 11:49

  • Furthermore, you normally install Linux software from binary packages. If you want the source code, you need to install a special source code package. – Álvaro González May 31 '17 at 11:52
  • I wanted to see with my eyes on my machine the class.arrayaccess.php. Maybe alongside it there are other interfaces I may find useful to learn. Just to see how the core of php works but judging from the repo seems like too much advanced for me. – thepassenger May 31 '17 at 12:05

php is written in C, so if you want to know how functions work I suggest you take a look at the source code for the interpreter.

  • Yeah I took a look there already but I have 0 knowledge of C so I doubt I'll learn much. I completely ignored the fact that the main core of php was in C. I'm just a beginner. Thank you for you answer. – thepassenger May 31 '17 at 12:06
