Documentation Examples Quest!

Hi!

We recently introduced WASM runnable-examples in the manual.

An example: 
https://www.php.net/manual/en/language.operators.assignment.php

We only enabled it for sections where we know the examples work, as they 
were not always written with runability in mind.

We need to evaluate each section on 
https://github.com/php/doc-en/issues/4799, and verify the examples, 
whether they need a fix, or need other tweaks to make it work.

For the random extension, this is what I did: 
https://github.com/php/doc-en/commit/1bcc40f8134305cbebf6c8378ee7e5fc8c569674

Will you help?

The instructions are in the ticket: 
https://github.com/php/doc-en/issues/4799

cheers,
Derick
