1- Jam-Packed with Type Declaration

This is the very first feature that we would like to cover. Taking about the older PHP versions, they were never a typed language (loosely typed) and this simply means that it is not likely to define the type of each variable during compilation. C, Java, Pascal are a few of those programming languages that are strongly typed that have been widely used in the deployment of critical software applications.

With this current PHP 7.4 publication, you can declare the data types by choice. Type declaration is a necessity for the reason that it can support you to define what should occur so that you get the anticipated results. In fact, even for you, it will make the code easier to comprehend.

(Here we demonstrate how to use this function as an example)

2- Arrow Functions: Your Ultimate Support System

This is the second most adored feature by the PHP community, and some even say that it took inspiration from the JavaScript language. . So, what function does it perform?

Well, there is only one function that it performs, and ‘it’s making the function syntax less wordy.’ We mean, don’t you prefer concise programming? It’s better, right?

Hence, taking about PHP 7.4 features and improvements, arrow functions agree to the usage of ‘short closures’ for writing one-line functions.

Before PHP 7.4, we had to use array_map as follows.

Too fancy, right? Honestly, it’s just this (??=) a shorthand to allocate a value to a variable it hasn’t been set previously.

4- Preloading in PHP 7.4

The support for preloading was added as a feature to enhance the performance of your code. In a nutshell, let’s see how this works.

Write a script that you want to add it on your Preloading and add it to opcache.preload directive in php.ini

PHP file will be executed when you (re)start the server and this can be used to preload additional PHP files, all preloading files will be saved in the memory and server will execute those files from memory, If needed to update, you have to restart the server.

For example you have to filter all your $_POST(s) on a certain criteria you should write the criteria in a PHP file and add it to your opcache.preload in this way you can easily filter all $_POST coming from different Forms.

5- FFI: Foreign Function Interface

FFI is a PHP extension that allows you to include with ease some externals libraries into your PHP code. That means it’s possible to use C, Go, Rust, etc. shared library directly in PHP without writing a PHP Extension in C.
