[PHP] PHP Embed (php_embed.h)

Hello.

I'am using embedded Zend Engine for executing PHP scripts and getting its output, I start making this basic example: PHP_embed_docs/embed.md at main · KapitanOczywisty/PHP_embed_docs · GitHub, and it's all ok, it works. The challenge come when I try to use it on an Apache custom module, I can compile it but when I restart Apache it says:

apache2: Syntax error on line 146 of /etc/apache2/apache2.conf: Syntax error on line 1 of /etc/apache2/mods-enabled/rst.load: Cannot load /usr/lib/apache2/modules/mod_rst.so into server: /usr/lib/apache2/modules/mod_rst.so: undefined symbol: php_embed_shutdown

libphp is well linked:
  ldd /usr/lib/apache2/modules/mod_rst.so
  linux-vdso.so.1 (0x00007ffeef78a000)
  libphp.so => /home/user/php-embed/libs/libphp.so (0x00007fd10fb2b000)
  ...

And it has embedded functions exported:
nm -D /home/user/php-embed/libs/libphp.so | grep php_embed
  00000000007ea477 T php_embed_init
  000000000157eac0 D php_embed_module
  00000000007ea5aa T php_embed_shutdown
  ...

I am working on Debian 12 Bookworm and tested packages 'php-embed', 'libphp-embed' and compiling PHP by myself with flag --enabled-embed, with the three methods I get the same results.

After tons of tests, I stopped testing and begin to try it in Nginx, in this server I can load it correctly and the server reloads well, but when I execute my php script with zend_eval_string (like in the functional example) it returns FAILURE.

Sorry, but what am I doing bad? Maybe Zend PHP Embed can not be executed in a custom HTTP server module?

Sorry for my English grammar, I'am giving my best effort. Thanks.
