October 30, 2020 — Of many great new features that PHP 8 has introduced, one of the most confusing that I found were called “Attributes”, until today. Attributes in PHP 8 got revised many times before gets settled to the current implementation that we will see in a bit.
October 26, 2020 — I’ve said it earlier and I’m saying it today as well that Composer is the backbone of modern development in the PHP landscape. It has been so much easier to pull in open-source packages into your projects which weren’t possible in the pre-Composer era.
October 16, 2020 — If you’ve ever worked on enterprise-level web applications, there’s a good chance that you would have in need to convert documents from one format to another such as converting an HTML document to PDF.

March 2, 2020 — Constructors are a really important part of the class-based object oriented programming. Through constuctors, a newly created objects initialize properties automatically before it is usable. In PHP, a constructor is a method named
__construct(), which the keyword

new statement is written, you also need to send the constructor arguments for the parameters.

$a is respectively less than, equal to, or greater than
February 18, 2020 — The usual and might be the most used way of cleaning the object is to use the good old __destruct() magic method in PHP. The magic method proves to be good in most of the cases. But there might be some scenario where even the
__destruct() method will fail. For instance, a scenario where your PHP script exceeds the maximum execution time, and terminates thusly. And a fatal error would occur called
Maximum execution time of 20 seconds exceeded in - on line XX.

For instance, the time when one of the class properties is of type array and you want to manipulate it just like you’d do with an array without exposing it during object creation. I’ve included a real world example of where this could be useful, at the end of the article. So, read on!
December 18, 2019 — Working with PHP, it would be pretty obvious you’d be worried about the performance of your application. And because of this anxiety, you start to optimize trivial things such as replacing double quotes(“) to single quotes(‘), use
echo instead of
print_r, or using static methods in order to gain those little performance gains during the initial few days of your application development itself. Optimizing these thigs is good and all.

October 30, 2019 — In this article, I’m going to discuss about the union types which are going to come in future versions of PHP through this RFC. To understand why and how are union types important in PHP, let’s first understand what are union types.
September 29, 2019 — PHP is funny sometimes. There are many things in PHP which behaves differently instead of the way you think might work. I recently stumbled upon one such thing while working on one of my projects.
September 2, 2019 — Passwords are an integral part of today’s authentication based web applications. In fact, Passwords have been used since ancient times. Sentries would challenge those wishing to enter an area to supply a password or watchword, and would only allow a person or group to pass if they knew the password. In modern web application passwords are used in combination with usernames to authenticate users. So, basically, we’d need to fields in order to store username and password for each user both of which are supplied by user at the time of signing up to the web application.

June 10, 2019 — In PHP, Invokables refer to any class that may be instantiated without any constructor arguments. In other words, one should be able to create an instance solely be calling

May 2, 2019 — With the introduction of scalar type declaration and return type declaration in PHP 7.0, the language’s type system got improved at some extent. Although it’s great to have some layer of strictness, it’s still missing the support to declare typed properties. But from PHP 7.4, it seems, it’s going to change because according to this accepted RFC, PHP 7.4 will be getting support for first-class property type declarations.

January 17, 2019 — PHP has evolved greatly as a language over the years. From a simple functional scripting language which initially started by Rasmus Lerdorf as his hobby project to supporting object oriented programming features PHP has come a long way. Although, PHP has been implementing and improving features of object oriented programming in its every release, there is this one feature which is missing and I’ve always wondered why it is not there in PHP all these years. Yes, I’m talking about multiple inheritance.
January 9, 2019 — When working on a project, there comes a time when you need to automate certain tasks. In such cases, it is better to use a CLI tool which can be run from the command prompt because using a web APIs for certain tasks is cumbersome.
December 21, 2018 — There comes times when you wouldn’t want your end users staring at white screens or that intimidating loaders for a long time. For instance when user registers to your site, you must have configured your website to send a welcome email or a confirmation email upon registering. So, that operation should be snappy and for that purpose you’d actually want to reduce the amount of time your app takes while sending the email to the user. Laravel Queues comes to the recue for achieving such kind of time consuming tasks.
December 8, 2018 — PHP development team has just released PHP 7.3 with general availability. This release brings general improvements along with some new features.

You search for a library for a concerned functionality and you’ll probably find the one in the large database of the Pacakgist.
