Add Arr method: toLocaleString()

[roberto-butti]

What

Add new method to Arr class, in src/Arr.php file

Description

The toLocaleString() method returns a string representing the elements of the array. The elements are converted to Strings using their toLocaleString methods and these Strings are separated by a locale-specific String (such as a comma “,”).
In PHP as far as I know there is no toLocaleString. My suggestion is to try to convert into locale string detecting the type

• number_format() if number
• date_format if it is date

see: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/toLocaleString

Checklist

• implement method
• write phpdoc for the function
• write test in tests/ArrTest.php
• execute composer format
• execute composer test-coverage
• check if your method has full test coverage
• add method in changelog
• update doc/arr.md adding a use case of the new method
• update cheatsheet (examples/cheatsheet.php)

@roberto-butti Hey there, I have just started looking at the issue and I have a couple of questions:

• What does a typical input array look like (esp. the dates)
• How is the locale set? do we guess it from the current env or should it be provided as a parameter

@roberto-butti I saw this issue, I would like to know if I can still work on it. And if so, I have a question, in the types where objects, functions and resources are, what should I do, leave it blank and continue?

hello thank you for your availability. Yes if the elements is not translatable into a string, you can convert it in a empty string (like if null os used in an element)
