Using Type Declaration instead of Type Hints

As my change has been reverted it seems appropriate to discuss the matter.

The PHP documentations refers to them as Type declaration, see: https://www.php.net/manual/en/functions.arguments.php#functions.arguments.type-declaration, and the original RFC introducing scalar types, uses the word "declaration", see: https://wiki.php.net/rfc/scalar_type_hints_v5 Although it is true that the PHP 5 documentation referred to them as "hints", and that the "Object Typehint" RFC is named as such but for all intent and purposes it is a type declaration.

Moreover, the word "declaration" is used in other places correctly instead of "hint", see:

PHP 7 also included new language features. Most notably, it introduces return type declarations for functions which complement the existing parameter type declarations, and support for the scalar types (integer, float, string, and boolean) in parameter and return type declarations.

Unusually for a dynamically typed language, PHP supports type declarations on function parameters, which are enforced at runtime. This has been supported for classes and interfaces since PHP 5.0, for arrays since PHP 5.1, for "callables" since PHP 5.4, and scalar (integer, float, string and boolean) types since PHP 7.0. PHP 7.0 also has type declarations for function return types, expressed by placing the type name after the list of parameters, preceded by a colon. For example, the getAdder function from the earlier example could be annotated with types like so in PHP 7:

By default, scalar type declarations follow weak typing principles.

(Emphasis mine)

As I'm new to contributing to Misplaced Pages, I don't know what to do about the following comment from the revert commit

"typehint" is the commonly used term in the community.

As sure it is referred to that but it is not accurate, and my understanding is that Misplaced Pages articles should be accurate.

Can someone more experienced clarify?

It's past 26 November so shouldn't it be in the past tense? by kaiete (talk) 20:25, 2 December 2020 (UTC)

Syntax highlighting

The syntaxhighlight tag does not support modern PHP syntax: 

$person = new class
{
    public $firstName = "John";
    public $lastName = "Smith";
    public function name(){
        return "$this->firstName $this->lastName";
    }
};

or 

class MyClass
{
    public string $var1;
    public array $var2;
    function pr(string|int $array, array|null $subj): float|false
    {
    }
}
$myObj->pr(subj: , array: "John");

Dropping legacy file extensions

The infobox currently has this for file extensions: 

php, phtml, php3, php4, php5, php7, phps, php-s, pht, phar

Some of these are extremely rare to see in the wild, like php3. I am wondering if it would make sense to drop these from the infobox, so we are left with just the common ones (roughly sorted by how common): 

php, phar, phps, phtml

And then perhaps we have a line somewhere in the article that explains why you might come across something like .php3 in a legacy system? Modern PHP just does not have all these silly extensions.

SampleCodes is instead of Screenshots in this Infoboxes

@Ancarda: Hi, SampleCode argument is new and it should be used is instead of the past argument "screenshot". See, SampleCode has an abstract description of the total language. It conveys important information about remaining parts of this Infobox. So we should use this argument as the rendering item, to successfully convey an overview of PHP language.
