BGGP #6 Entry: All 6 x BGGP's! Zip/Shell in 179 bytes

I set out to cover as many of the BGGP challenges as I could and went on quite a journey to get there!

Initially I started out with this structure, planning to randomly output a challenge and replace ls later with perhaps a :(){ :|:& };: fork bomb:

	SELECT SQL_CALC_FOUND_ROWS , FROM huge_table;
	/* Then as 2nd query straight after... */
	SELECT FOUND_ROWS() AS totalRows;
	/* ...to get total records found */

	<?php
	$root = '/xampp/htdocs/repo';
	$iter = new RecursiveIteratorIterator(
	new RecursiveDirectoryIterator($root, RecursiveDirectoryIterator::SKIP_DOTS),
	RecursiveIteratorIterator::SELF_FIRST,
	RecursiveIteratorIterator::CATCH_GET_CHILD // Ignore "Permission denied"
	);

	function has_gitignore_file($dir) {
	return is_file("$dir/.gitignore");

	<?php
	// Function to sort given values alphabetically
	function alphasort($a, $b) {
	return strcasecmp($a->getPathname(), $b->getPathname());
	}

	// Class to put forward the values for sorting
	class SortingIterator implements IteratorAggregate {
	private $iterator = null;
	public function __construct(Traversable $iterator, $callback) {

	Looking for functions to clean vars for different situations.

	Can you improve on these, returning strings, urls and numbers:

	function strClean($var) {
	// returns converted entities where there are HTML entity equivalents
	return htmlentities($var, ENT_QUOTES, "UTF-8");
	}

	function urlClean($var) {

	var parser = document.createElement('a');
	parser.href = "http://example.com:3000/pathname/?search=test#hash";

	parser.protocol; // => "http:"
	parser.hostname; // => "example.com"
	parser.port; // => "3000"
	parser.pathname; // => "/pathname/"
	parser.search; // => "?search=test"
	parser.hash; // => "#hash"
	parser.host; // => "example.com:3000"
