PHP Dotenv VS rust

After successfully setting up our project, you'll observe that certain packages come pre-installed. One of these packages is vlucas/phpdotenv. This package serves the purpose of facilitating the loading of .env variables within your projects. These variables, stored in a file named '.env', allow for the configuration of various settings without hardcoding them directly into your code. Instead, you can define environment-specific variables such as database credentials, API keys, or any other sensitive information in the .env file, providing a more flexible and secure approach to configuration management.

Recently, I jumped to reading on the documentation of the function putenv() and define() and the array $_ENV to understand the different between all. Also, I looked at the library phpdotenv and how it handles environment variables since its the standard approach to go with when dealing with environment variables in PHP.

So to get down to it, what are some of the best practices here? First off, things that you would normally do, like utilize some sort of secrets manager, that won't be available to you. You also can't utilize environment variables with apache. So you're going to have to have some sort of local secret (password/passphrase) to perform the encryption/decryption. With that said, mysql does provide AES encryption with their AES_ENCRYPT/AES_DECRYPT calls, so in that manner, yes you can safely store PII or other values in a shared MySQL. You can use a php library like https://github.com/vlucas/phpdotenv The decryption password(s) should be in the .ENV file Nothing prevents you from utilizing some scheme perhaps to provide multiple passwords if you want to, perhaps a separate one for each individual column you plan to encrypt.

DotEnv - a popular library that allows us to use environment variables in our project.

[PHP dotenv.](https://github.com/vlucas/phpdotenv) Loads environment variables from `.env` to `getenv(), $_ENV` and `$_SERVER`

PHP dotenv. Loads environment variables from .env to getenv(), $_ENV and $_SERVER automagically.

Use this library https://github.com/vlucas/phpdotenv. Hopefully you are using composer. If not, please consider using it.

First, we need to have PHP installed as well as Composer (A dependency manager for PHP). Using Composer, we need to install dotenv which will allow us to read .env files.

Here, I'm using the vlucas/phpdotenv library to process .env files.

If you haven't dipped your touch-typing fingers into Rust yet, you really owe it to yourself. Rust is a modern programming language with features that make it suitable not only for systems programming -- its original purpose, but just about any other environment, too; there are frameworks that let your build web services, web applications including user interfaces, software for embedded devices, machine learning solutions, and of course, command-line tools. Since a custom GitHub Action is essentially a command-line tool that interacts with the system through files and environment variables, Rust is perfectly suited for that as well.

Here's an example of someone citing a disagreement between CRT and shell32:

This in addition to the Rust CVE mentioned elsewhere in the thread which was rooted in this issue:

Here are some quick programs to test contrasting approaches. I don't have examples of inputs where they parse differently on hand right now, but I know they exist. This was also a problem that was frequently discussed internally when I worked at MSFT.

> instead of choosing a certain numbered version of the random library (if I remember correctly) I let cargo download the latest version which had a completely different API.

Yeah, they didn't follow the instructions and got burned. I still think that multiple things went wrong simultaneously for that experience. I wonder if more prevalent uses of `#[doc(alias = "name")]` being leveraged by https://github.com/rust-lang/rust/pull/120730 (which now that I check only accounts for methods and not functions, I should get on that!) so that when changing APIs around people at least get a slightly better experience.

Almost fixed the compiler: https://github.com/rust-lang/rust/pull/123325

Rust: A secure, efficient, and modern programming language (omitting ten thousand words). You can simply follow the installation instructions provided on the official website.

Recently did something similar in Rust but for generating SVGs. We've adopted it for snapshot testing of cargo and rustc's output. Don't have a good PR handy for showing Github's rendering of changes in the SVG (text, side-by-side, swiping) but https://github.com/rust-lang/rust/pull/121877/files has newly added SVGs.

To see what is supported, see the screenshot in the docs: https://docs.rs/anstyle-svg/latest/anstyle_svg/

We strongly believe in Rust as a powerful language for building production-grade software, especially for systems like ours that run alongside Kubernetes.

The above Assert<{N % 2 == 1}> requires #![feature(generic_const_exprs)] and the nightly toolchain. See https://github.com/rust-lang/rust/issues/76560 for more info.
