C-Sharp VS PHPT

What I initially viewed as a challenging and sometimes even daunting process transformed into a school of resilience and excellence. The lessons I absorbed from TheAlgorithms were not just theoretical but practical. They found their way into my professional work, where I began to apply the same level of meticulousness and precision. The experience reminded me that in the world of coding, attention to detail and adherence to strict standards can make all the difference between code that merely functions and code that excels.

The previous post on this blog makes another worthless comparison, this time based on lines of code:

> Like, look at this Merge Sort in C# [1] (130 lines) and then look at it in PHP (31 lines) [2]. You can’t beat that kind of productivity, not to mention in PHP, you can even mix data types (like ints and floats) where in the C# version, it’d be much more difficult.

The C# version is the first Google result for "c# merge sort". But a later result is from w3resource.com, which where the PHP code came from. That C# code is only 55 lines and could easily be shorter by replacing loops with standard library calls:

Also, both versions of the code from w3resources.com are trash -- they use an O(N) step to remove an element from the front of the array (array_slice in PHP and List.Remove in C#), which makes them O(N^2 log N), which is even worse than a naive selection sort or bubble sort.

Well, except the better C# comparison would be this one (same place, but sorts an array, not an ISequentialStorage, which the PHP version doesn't even attempt): https://github.com/TheAlgorithms/C-Sharp/blob/master/Algorithms/Sorters/Comparison/MergeSorter.cs

There's a much more sensible C# merge sort implementation in the same repo as the oddly-over-the-top one linked in the article, which is very very close to the PHP one: https://github.com/TheAlgorithms/C-Sharp/blob/master/Algorit...

In our latest story we show a couple of smart ways to get around some import conflicts in PHP.

The values [0, 15] represent 16 possible values, which is a power of 2.

The correct way to get an unbiased distribution from a sample of 2^x to a modulo that is not an even power of 2 is to use rejection sampling.

This is what RFC 6979 says to do https://datatracker.ietf.org/doc/html/rfc6979#section-3.2

But you can also see this technique in CSPRNG code; i.e. https://github.com/php/php-src/blob/d40726670fd2915dcd807673...

I am running this code on MacOS on Apple Silicon hardware which is crashing when using the JIT in a ZTS build of PHP, so the 1m 35s result is without JIT, it might be even faster if I could use it

A little about me; I'm a web developer and have been for around 5 years, though I'd dabbled for years. I have experience with Perl and PHP but my day to day is JavaScript/TypeScript be it through NodeJS or ReactJS. I want to learn Rust for no specific reason other than it's fun to learn new things.

Consider a web application where requests are handled through NGINX as the web server and PHP as the dynamic backend language. Let’s say something in the application logic results in a fatal error or process termination. This doesn’t affect NGINX’s ability to serve a response to the client, which would most likely be an HTTP 503 - Service Unavailable message.

In the beginning, I used a technology called CGI to develop server applications written in Perl. This technology was later replaced by Microsoft’s ASP (Active Server Pages) and then PHP. PHP, which you may already know, is still powering over 77% of all the websites as of the time of writing (ever heard of WordPress?).

PHP

As Shopware is mostly based on the Symfony framework, which is in turn based on the PHP language, we should also consider learning about the basics, which will also be useful for other frameworks apart from Shopware, like Symfonycasts, symfony.com, php.net.
