I had the opportunity to chat with @asgrim.dev yesterday about PHP Pie - the new installer for PHP extensions, intended to replace PECL.

Full interview dropping tomorrow.

It is easy to create a map from a list of object, using #PHP array_column() and the second argument null.

That null represents the whole object, and the third argument is the indexing key.

array_column($list_of_objects, null, 'id');

It is not possible to cast any #PHP enum cases to (string) or (int) even when... they are backed!

That looks like a natural feature, though.

Dynamic class constants is achieved with #PHP 8.3 class constant syntax, and the constant() function.

It also applies to enumeration cases.

I ran into a 2011 #PHP ASCII art generator, and the code works perfectly on PHP 8.5.

#PHP callable arrays are checked for 2 elements and only using index 0 and 1.

No one said that 0 and 1 have to be in that order, and it works perfectly!

Well done #PHP, well done!

There are, at least, 4 ways to create a closure in #PHP. They all will be callable later.

On the other hand, they behave differently to check the underlying method.

All is in the timing.

A few days ago, I warned about isset() and a possible #PHP Fatal error.

Given that isset() and ?? share the same code, it is not suprising that ?? hold the same trap.

That bug should go away, the sooner the beter.

When using #PHP isset(), the language construct hides errors because, that's what is being tested there.

Unless there is an object, where an array is expected. Then, it leads to a fatal error.

It prevents the usage of an optimisation.

It is Friday, so why not cram as many #PHP operators in one single operation, and make it work?

Look at this beauty! Could you make it run?

A rare find: A syntax that worked before #PHP 8.1 and after #PHP 8.2 but not in #PHP 8.1

Here is the never arrow function.

Let's do it again with the latest released version, PHP 8.4, for all #Symfony/#Laravel/vanilla PHP fans 🚀

Here are 11 FEATURES you probably don't know about the current PHP version 🧵👇

The third way to cast a #PHP variable to integer is to use the + sign on it.

Another Cast To Int
Another way to cast a value to int, besides the obvious ``(int)`` operator and the classic ``+ 0``, is to use the unary operator ``+`` operator on a variable: it add a sign operation on the variable, ...

So, take a #PHP array, but some value in it (like, anything).

Can you make an infinite loop out of this?

#PHP properties may be a reference.
#PHP properties may be promoted.
#PHP properties may have a hook.

Just not both at the same time.

#PHP mixed type accepts any type, just like no type. But it is also making property unreadable before initialisation.

And that's often a useful check.

mixed Is Not No Type
When a property is not typed, nor has a default value, it still may be accessed freely: its value is ``null``

In #PHP array_merge_recursive(), what is recursive?

Does it go deep in the guts of the arrays, or does it merges values that look alike?

Or something else?

Did you know that #PHP 's own $GLOBALS variable is actually undefined?

I'm going to miss the hedonism of those error messages once they are all fixed.

The humble bitwise operators (& ^ | ) have a hidden secret : they work on integers and also on strings.

But not on both at the same time.

One of the earliest #PHP feature, still available 30 years later.

#PHP and Rotterdam is a love story. A huge crowd of PHP aficionados congregated to treehouse, to listen to Gina and eat cake.
