Subject: Re: [PHP-DEV] PHP build for the wasm32-wasi target
From: office.hamzaahmad@gmail.com (Hamza Ahmad)

HI Rafael,

I am happy to here that you guys are working on this. I once thought
of writing such a solution myself for PHP when I learnt it compiled c.
However, I could not manage time. I am positive it will be useful.

NVM< I don't know why Google has marked your email as spam. Likely,
that's why, you have not been responded as yet.
