American Fuzzy Lop VS PHP CPP

There's some efforts to guide test generation for property based testing to make the instruction pointer explore as large a space as possible.

This effort is more mature in the fuzzing community. See eg American Fuzzy Lop https://github.com/google/AFL

What you're describing, just generating random input to test a program, is sometimes called "blind fuzzing" but the state-of-the-art is far beyond that. Maybe try reading through the documentation of e.g. https://github.com/google/AFL to see what a fuzzer does and why just producing random input isn't even scratching the surface.

for general riscv I used to use this https://github.com/google/AFL I dont know if it supports x64 tho.

Ex ( AFL, WinAFL, HonggFuzz, LibFuzzer, Jazzer )

I wrote this little fuzz test target in order to fuzz it with afl (under ASan and UBSan):

afl, which is trivial to apply to this program:

I made my own version of a TCL interpreter (well, a very TCL like langauge) derived from "picol" available at https://github.com/howerj/pickle. There are many different re-implementations and derivatives of this interpreter but they all seem very "crashy", this one has been significantly hardened by using a fuzzer on it which ran for months called American Fuzzy Lop https://lcamtuf.coredump.cx/afl/ . It is also more suitable for embedded use whilst still not having arbitrary restrictions like many other implementations.

On Linux afl is a very powerful bug-finding tool, and it's a great companion when doing code review. Composes well with ASan and UBSan.

Look at things like how Hydration in PHP can done. Look also at PDO directly and how you can choose to get an array, or object back from the database directly from the driver (https://www.php.net/manual/en/pdostatement.fetchall.php ). Look at how to create a underlaying C++ library that can talk directly to the hardware (http://www.php-cpp.com/ ). Use PHP as a first class Templating language as this is what it was designed to do (https://www.ntchosting.com/encyclopedia/scripting-and-programming/php/php-in/). Pro tip, you don't have to template HTML, PHP can "template" anything that returns a stream.

Small description about repository: phptdlib is a PHP extension for the Telegram Database library, which allows to create Telegram clients. This is a CMake based C++ project with dependencies (tdlib/td, CopernicaMarketingSoftware/PHP-CPP and nlohmann/json), which produces a PHP extension.
