How do you sort a list of words on the 4th character of the word? What"s the shortest solution?

[ "strawberry", "helicopter", "wales", "acorn" ]

should be:

Given a string s, where * represents a star…

Remove the star along with its closest non-star character to its left in a single operation.

The task is to perform this operation until all stars have been removed and to return the string that remains.

In this challenge you get an HTML document that renders a lot of colourful hearts.

And you get a JSON object with the information about all the brown colours that were used:

	<?php

	function convertfilename($filename) {
	$filename = str_replace([ "?", "[", "]", "/", "\\", "=", "<", ">",
	":", ";", ",", "'", '"', "&", "$", "#",
	"*", "(", ")", "\|", "~" ], "", $filename);
	$filename = preg_replace("/[\s-]+/", "-", $filename);
	$filename = trim($filename, ".-_");
	return ucwords($filename);
	}
