Module and PHP versions need to match

[shdblowers]

Hi, running through the hello world tutorial in the docs, I get an error in the following step:

$ php -d extension=./target/debug/libhello_world_php_rs.so test.php
PHP Warning:  PHP Startup: hello_world_php_rs: Unable to initialize module
Module compiled with module API=20220829
PHP    compiled with module API=20230831
These options need to match
 in Unknown on line 0
PHP Fatal error:  Uncaught Error: Call to undefined function hello_world() in /home/steven/sandbox/hello_world_php_rs/test.php:3
Stack trace:
#0 {main}
  thrown in /home/steven/sandbox/hello_world_php_rs/test.php on line 3

This is the version I'm running:

$ php -v

Make sure you've installed the correct version of the php development dependencies.
