Placeholder

Library provides a placeholder implementation for currying functions, partial applications, pipe operator, and other syntactic structures hat allow specifying default values.

Usage

What is "placeholder"?

<?php

var_dump(is_placeholder('_'));
// expected output: false

var_dump(is_placeholder(_));
// expected output: true

For example we can replace each of the placeholders in the array with the required value.

<?php
use Serafim\Placeholder\Placeholder;

$array = [1, _, 3, _];

$result = Placeholder::map($array, fn() => ' map ');

echo implode(', ', $result);

// expected output: "1, map, 3, map"

And... Thats all =)
