Loads all JavaScript files in a directory, and echos back their contents. Needs some work, but it works for a quick hack during development when dealing with lots of javascript files.

alljs.php

<?php
//To echo everything alphabetically:
//	includeJS("./");
//includeJS can take an entry set or a path.
//For getting an entry set:
//	getJSEntries($path [, $baseentries = []])
//$baseentries can be specified so that all file entries within $baseentries will be ignored.
//If $path is a file, it adds that file to the existing entries (specified by $baseentries).
//If $path is a folder, it does the same as the above for each file. Note that folder searches are recursive.
//The return result is the $baseentries array, merged with the sorted results of getJSEntries.
//To echo the contents of the final product, do:
//	includeJS($entries);
function getJSEntries($path, $baseentries = [])
{
	$entries = [];
	if (is_file($path))
	{
		if (!in_array($path, $baseentries))
		{
			$baseentries[] = $path;
			return $baseentries;
		}
	}
	else
	{
		if ($dir = opendir($path))
		{
			while (($entry = readdir($dir)) !== false)
			{
				$isDir = is_dir($path . $entry);
				
				if ($isDir )
				{
					if (strpos($entry, ".") === false)
						$entries = array_merge($entries, getJSEntries($path . $entry . "/"));
				}
				else
				{
					if (strpos($entry, ".js") !== false)
						$entries[] = $path . $entry;
				}
			}
		}
	}
	sort($entries);
	return array_unique(array_merge($baseentries, $entries));
