Add function array_to_str() in Array helper

[dixy]

This function is the same as the implode() function, but you can change the string between the last and last-1 elements.

<?php
$arr = array('apple', 'banana', 'kiwi');
echo array_to_str($arr, ', ', ' and'); //returns "apple, banana and kiwi"

function array_to_str($array = array(), $sep = ', ', $sep_last = '')

You can set default empty array.

Yeah, that would probably be preferable.

What's the point of having $return = '';?

[appleboy]

Delete $return variable?

[appleboy]

@chrisberthe I think he forgot to delete it.

[dixy]

Yes, I forgot to remove it

[kylefarris]

I like this idea. It would actually be quite useful! Thanks for the pull request.

This is way too outdated and is achieveable via 2 lines of code anyway. Please resubmit it based on the latest develop if you still want it.
