php-types
=========

[](#php-types)

Named typed constants and predicates — give meaning to magic literals.

A raw `''`, `[]`, `'{}'`, `0`, `true`, or `null` carries an unstated intent and gets re-checked defensively all over a codebase (`if ($this->delimiter === '')`). These tiny static classes give that intent a name and the check a single home.

```
use JesseGall\PhpTypes\T_String;

$prefix = T_String::empty();              // '' with a name
if (T_String::isEmpty($delimiter)) { … }  // reads as intent

// as a first-class callable
$nonEmpty = array_filter($parts, T_String::isNotEmpty(...));
```

Types

[](#types)

-----------------

[](#deferred-defaults)

`Defaults` returns a zero-argument `Closure` that produces a type's default — for when a place wants a *callable* yielding the default rather than the value:

```
$make = Defaults::array();   // Closure(): array{}
$make();                     // []

// e.g. a resolver factory or a lazy fallback:
IsNull::make()->then(Defaults::array());
```

`Defaults::array()`, `string()`, `int()`, `float()`, `bool()` (`false`), `null()`. For the value directly, use the type's own accessor (`T_Array::empty()`, …).

`T_Json` predicates are semantic — `isEmptyObject('{ }')` and `isEmptyObject("{\n}")`are `true` (they decode to an empty object), while `isEmptyObject('[]')` and invalid JSON are `false`.

Install
-------

[](#install)

```
composer require jessegall/php-types
```

Requires PHP 8.2+. Zero runtime dependencies.

Test

[](#test)

```
composer test
