Typed

This libaray allows you to create typed variables in PHP 7.4 +

example :

<?php declare(strict_types=1);

$name = &string('saif');
$age = &int(19);

try {

  $name = 'azjezz'; // works
  $name = 15; // fails
  $age = null; // fails

} catch(TypeError $error) {
   
}

// based on the passed variable type
$string = &typed('saif');
$traversable = &traversable(new ArrayObject());
$countable = &countable(new ArrayObject());
$func = &func('strtolower');
$object = &object((object) []);
$stdClass = &stdClass((object) []);
$iterable = &iterable([]);
$bool = &bool(false);
$bool = &boolean(true);
$set = &set(['a', 'b', 'b', 'a']); // ['a', 'b']
$vector = &vector(['a' => 1, 'b' => 2]); // [1, 2]
$array = &arr(['a' => 1 , 'b' => 2]); // ['a' => 1, 'b' => 2]
$keyset = &keyset(['a' => 1, 'b' => 2]); // ['a', 'b']
$int = &integer(5);
$int = &int(48);
$string = &string('f');
$float = &float(1.56);

callable => func, array => { arr, keyset, vector, set }

Since callable and array cant be used for function names, instead i have used func for callable and arr for array. keyset, vector and set are just helper to help you create an array of keys ( keyset = arr(array_keys($value)) ), an array of values ( vector = arr(array_values($value)) ) and an array of unique values ( set = arr(array_unique($value)) ).

typed

typed() is a function to help you create a typed variables based on the type of the passed variable, currently it supports string, int, float, bool, object and iterable. it was suggected by @mikesherov on twitter.
