Hello!

I am trying to create a simple function to check whether to show an image or display the contents of a file.  If the input is an image-type, show it as an image, and if it's text-type, show it's source code.

I figured the best way to do this was to grab the file extension, and work from there.  Here's my code:

----------
$filetypes=array(
		"text" => array("txt","php","xml","html","htm","cgi"),
		"image" => array("png","jpg","jpeg","svg","bmp")
	);
$type=array_search("png",$filetypes);
echo $type;
----------

Basically, I want it to return 'image', in this case, because the supplied input 'png' is in the 'image' key.  However, array_search doesn't check arrays within arrays.

If array_search could possibly be updated to provide a search within multidimensional arrays, that would be fantastic!

Thanks!

Test script:
---------------
//Filetypes array, one key for text and one key for image extensions (shortened)
$filetypes=array(
		"text" => array("txt","php","xml","html","htm","cgi"),
		"image" => array("png","jpg","jpeg","svg","bmp")
	);
//Look through the array for 'png', and return it's respective key.  Then echo it.
echo $type=array_search("png",$filetypes);

Expected result:
----------------
I expect it to return 'image'.

Actual result:
--------------
(null, no output)
