If you are looking for some code execution path, you are better to use
gdb (or any other debugger).

script:
<?php
echo 123;

Set breakpoint at zend_execute(), then you'll get following stack
(PHP 7 CLI) or like.

0 in zend_execute of
/home/yohgaki/git/oss/php.net/php-src/Zend/zend_vm_execute.h:437
1 in zend_execute_scripts of
/home/yohgaki/git/oss/php.net/php-src/Zend/zend.c:1400
2 in php_execute_script of
/home/yohgaki/git/oss/php.net/php-src/main/main.c:2471
3 in do_cli of /home/yohgaki/git/oss/php.net/php-src/sapi/cli/php_cli.c:971
4 in main of /home/yohgaki/git/oss/php.net/php-src/sapi/cli/php_cli.c:1342

You're better to read Zend code briefly if you would like to do
something with Zend.
