[#]PHP 8.4 is deprecating the usage of _ (underscore) as a class name. Anyone knows why?

The same name is available for functions, methods and constants, so, with named parameters, we can still write the beauty below.

When using dynamic code with #PHP, the code must provide a string for the method or property name. Although,

• for methods, a non-string yields a Fatal error

• for properties, a non-string yields a silent type cast to string. That helps.

Two things that surprised me today, with static.

First, it looks like a 'static' typed property, until I read the default value. It took me a while to figure out.

Secondly, static properties may be inherited, or be distinct from the parent: redefine it in the child, and that segregate them. 😮

[#]PHP trick question, for the Friday developer: where do you put the parenthesis in a new call:

• before the class name

• on the class name

• after the class name

• nowhere

• somewhere else

• all of the above

"Cannot call constructor" is a real #PHP error message. And there is also "Must call the parent constructor".

To call or not to call the constructor: definitely a question, and may be, an improvement for #PHP 8.5.

I already knew that #PHP is

• a dentist in The Hague,

• a Banana plantation in Cameroon,

• an airport in North Dakota,

• a French Rear-admiral,

• a Highway patrol in Pakistan,

but TIL it is also a hairdresser in slovakia.

And you? What is your own special #PHP meaning?

So, #PHP has fluent interfaces, but it also can do fluent functions: functions that can be chain called.

As usual, it works but it is a tad cumbersome.

A #PHP global constant redefinition is a simple warning.

A #PHP class constant redefinition is a full Fatal Error.

I am so used to the Fatal error, that I expected the global constant to behave the same. Shouldn't they?

Junior dev: I really really want to use {$a::class} inside a double-quoted #PHP string, but it gives a syntax error!

Me, an intellectual: Hold my beer.

There is a deprecation notice, that request to return an integer, not a boolean, for the custom sorting function of #PHP usort().

Well, it is not harmless, and should be taken seriously.

Passing a literal by reference is a Fatal error,

while returning the same literal by reference is a notice.

How many ways do you know to call a #PHP method in the code ? There are obviously 2 very common ones, but there are a few others, that serve a niche usage.

How unique are #PHP anonymous objects?

They are all distinct, unless the code of definition is reused multiple and distinct times. Then, such objects are of the same class.

It's a bit weird to understand.

TIL that there are two ways to protect characters in a #PHP regex : preg_quote() and \Q .... \E.

It looks scary, but it might be very useful indeed.

How can you get an 'undefined variable' on the same line where the variable is defined?

All is a matter of execution order. Probably not even #PHP related.
