From manual page: http://www.php.net/function.array-search
---

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)

Hi, this should be a bogus. array_search does not search recursively.

> array_search does not search recursively.

Actually, this is what the OP requests as enhancement. I'm not
sure if that would make sense, generally, though. At least the
given use case appears to be bogus, as the $filetypes array could
be laid out like so:

    $filetype = array(
        "txt" => "text",
        "php" => "text",
        "xml" => "text",
        "html" => "text",
        "htm" => "text",
        "cgi" => "text",
        "png" => "image",
        "jpg" => "image",
        "jpeg" => "image",
        "svg" => "image",
        "bmp" => "image"
    );

And the "search" be done so:

    echo $type = $filetypes['png'];

That's easy to understand and much more effecient, anyway.

Can you present a better use-case, pgreviews?
