😂 This made me chuckle... welcome to #PHP 8.3 !

First array is the type, the second is the name of the constant, with the relaxed keyword, and the last one is the value of the array.

A good way to meet your soon-to-be new #PHP 8.3 version is to read about its error messages. Now or later, what's the difference ?

Choose your team : condition in a loop, or array_filter() first ?

Make up your mind, and then you can read this new blog post.

The result will NOT surprise you.

How big are your #PHP source code ? Excluding dependencies (vendor folder)

Generally, #PHP is quite compact code, and requires few expressions to achieve its goal.

The largest OSS are 4.9 MLOC (una, bitrix), while the majority is well below 2 000. The figures below partition OSS projects in 4 part of equal size.

Where are you ?

The #PHP (array) operator is a simple cast to array. Yet, it is one of the less obvious feature of the language : (array) on integers, on null, on objects, recursive and hidden.

That's a lot to discover for the oldest and most useful operator.

Comparison of memory usage and execution speed between #PHP associative arrays, named and anonymous classes, stdClasses and extended classes, across PHP versions.

TLDR; using classes is more memory efficient, and a bit faster.

Useless tip of the day:

#PHP Null and booleans accept the array syntax, but always return NULL (and a warning)

Illegal types for array keys lead to a Fatal Error.

But not with NULL and booleans.

Here is another way to make recursive calls in #PHP : use the generator delegation.

The main difference is that it needs to be in a foreach() or a generator using function.

One year ago, we were waiting eagerly for #PHP 8.2 and its new features. Now, let's see how those features were adopted in the code repositories.

This means you, DNF types, readonly classes, constants in trait, true/false types.

All the recursive functions in #PHP

From classic recursive functions to their quirky cousins like recursive methods, closures, and arrow functions – it's a whole zoo!

Indirect, abstract, and even distributed recursive functions add layers to the complexity. Embrace the challenges and beauty of recursion in #PHP!

Running @Exakat on an application server will make it faster and more flexible. And there comes FrankenPHP!

Here is the port of a complex CLI intensive application on FrankenPHP, and make it run. It was both teaching and straightforward.

#PHP foreach() works on arrays and objects. On objects, it skips uninitialized properties, which may be very convenient with readonly properties : otherwise, it is a fatal error!

In the list below, there is one #PHP fatal error. All others are working as expected, except for the fact that they probably should yield an error and be not legit.

The error says : "Cannot use [] for reading".

Did you guess the one?

To make a class alias, use class_alias();
To make an interface alias, use class_alias();
To make an enum alias, use class_alias();
To make a trait alias, use class_alias();

Also, no ::enum operator, ::trait operator?

TIL file_put_contents() accepts an array as second argument, and will do an implode("", $array) on it when writing.

Who is using this feature?

In this code, #PHP complains about an unexpected semi-colon, which... doesn't exist.

It is actually the closing tag, which acts as a end of command.

A story of #PHP compact() and extract()

I finally found an occurrence of this beauty :

$this->$this

It still looks like a typo in the original code, but with the help of #PHP __toString, it works. Also, strict_types doesn't help here.
