⚡ 𝗘𝘅𝗽𝗹𝗼𝗿𝗶𝗻𝗴 𝗗𝘆𝗻𝗮𝗺𝗶𝗰 𝗟𝗜𝗡𝗤 𝗮𝗻𝗱 𝗖# 𝗘𝘃𝗮𝗹 𝗘𝘅𝗽𝗿𝗲𝘀𝘀𝗶𝗼𝗻 Ever wondered how you can build powerful runtime queries and dynamic expressions in C#, without endless if-else conditions or hardcoded logic? That’s where Dynamic LINQ and C# Eval Expression shine. In my latest carousel, I break down how these libraries let you: - Create and execute LINQ queries dynamically at runtime. - Evaluate and compile C# expressions on the fly. - Replace complex branching with clean, flexible logic. - Empower your APIs and backend systems to handle dynamic filters, sorting, and calculations effortlessly. If you’ve ever needed to let users define filters, formulas, or rules dynamically, these tools will change how you think about C# flexibility. 👉 Swipe through this document to learn more about these amazing libraries and what can you achieve with them. You can try these libraries today: - Dynamic LINQ ➡️ https://lnkd.in/eGD-Bhqh - C# Eval Expression ➡️ https://lnkd.in/eGB-Nvyb What’s one scenario where you’d benefit from runtime queries or expressions in your code? Share your experience in the comments. 👇 And repost if you think this is useful. ♻️ P.S. Thanks ZZZ Projects for building and supporting these powerful libraries, and for sponsoring this post.

You can serialize #php objects for easy transmission or storage. The __serialize and __unserialize methods give you the ability to define how an object will be serialized and unserialized. When serialize() is called on an object of the class, the __serialize method is invoked. This method is responsible for returning an array of key-value pairs that represents the data you want to serialize. In the attached example, only the $host and $user properties would be serialized, and the $password property would not…and this is what the serialized object actually looks like: "O:6:"Config":2:{s:4:"host";s:9:"localhost";s:4:"user";s:4:"Gary";}" 🤔 If you want me to explain what 👆 this string actually means and also show you how __unserialize works, I cover it all in Learn Object oriented PHP..plus a ton of other stuff that you’ll need to know.

Mastering SelectMany in C#: Flattening Nested Collections Like a Pro If you’ve ever worked with collections inside collections in C#, you’ve probably faced the challenge of transforming them into a clean, usable sequence. That’s where SelectMany shines. SelectMany in LINQ lets you project each element of a sequence into an IEnumerable<T> and then flatten all those inner collections into one unified sequence. 📌 Why it’s a game-changer: ✅ Flatten nested collections – Perfect when each item in a list has its own list and you want a single, flat structure. ✅ Simplify complex queries – Makes your LINQ code more readable and eliminates the need for nested loops. It’s one of those methods that makes C# LINQ both elegant and powerful — once you understand it, you’ll start seeing opportunities to use it everywhere. 💭 Have you used SelectMany in your projects yet? If so, where did it make the biggest difference? 🧠 Subscribing to my free newsletter – .𝙉𝙀𝙏 𝙒𝙚𝙚𝙠𝙡𝙮 𝙏𝙞𝙥𝙨 𝙗𝙮 𝙋𝙤𝙤𝙧𝙣𝙖.

Laravel Devs, a few months ago we did a poll on where to define middleware—whether in routes or controllers. 🤔 Some of you mentioned that with resource routes, we had to either define middleware in the controller or break the route into separate ones for specific methods. 👀 Well, I’ve got you covered! From Laravel 11.38, you can now add or exclude middleware for specific methods directly in the route! 🛠️ PR: https://lnkd.in/dcfU_DCv

🔥 The Surprising Performance of PHP 8.4’s array_find Did you know the new array_find function in PHP 8.4 is actually slower than a regular foreach loop—and even its own version rewritten in pure PHP? 🤔 I ran benchmarks with datasets of 100, 10,000, and 100,000 elements, and here’s what I discovered: - Native array_find is about 4.9x slower than foreach. - A pure PHP implementation of array_find is about 1.6x slower than foreach. While the differences are small and unlikely to matter in most real-world applications, they reveal some fascinating insights into PHP performance. For developers who value simplicity, the native array_find may still be a great choice, but the trade-offs are worth noting. Would you use array_find for its convenience, or stick to foreach for better performance? Let’s discuss! 💬

When writing unit tests in .NET, you may need to verify that methods are logging exceptions & other key info. But simply mocking ILogger using a mocking library doesn't work for some common methods. Here, Grant shows you how to get around this using a .NET 8 and up feature called FakeLogger. https://buff.ly/4322JjD

🔹 Practical C# Tip Every Developer Should Know 🔹 Have you ever used the ?? (null-coalescing) operator in your C# code? It’s a simple, elegant, and powerful way to avoid NullReferenceException and make your code cleaner and more expressive. Instead of writing conditionals to check if a variable is null, you can define a default value in just one line. Recently, I worked on an API where it was common to receive partially filled objects. A specific field, like patient.Name, wasn’t always provided, which caused issues when displaying data or saving logs. Instead of writing: ❓ var name = patient.Name != null ? patient.Name : "Name not provided"; I used: 💡 var name = patient.Name ?? "Name not provided"; Much cleaner, right? This kind of syntax helps me a lot in my daily work, especially when dealing with DTOs, external integrations, or partial form submissions. It also reduces the number of lines and improves readability—especially in more complex methods. 💬 How about you? Do you already use the ?? operator in your code? What other C# tips make your daily coding easier and deserve more attention? #dotnet #csharp #softwaredevelopment #backend #codetips #cleanCode #devlife #programming #developer #dotnetcore #backenddeveloper

🔐 Data encryption in Laravel environments is based on one secret: the APP_KEY. Our ninja R��mi M. studied the potential impact of its leakage on the internet during an entire year. 🍿 This research is the continuation of the talk we gave during Grehack 2024, and includes a lot of new juicy details! 📚 In this blogpost, you will find: - How the APP_KEY is used in Laravel during encryption, and why it can lead to the server compromise. - The methodology used to identify publicly exposed Laravel instances on the internet, as well as the retrieval of their APP_KEY. - A thorough analysis of the findings and the conclusions drawn from this research. 🛡️ We also had the pleasure to work with GitGuardian research team on some parts of this subject, check out how far a collaboration like this one can push a security research! https://lnkd.in/eswepy_3
