Req #55389 [Opn->Fbk]: Feature suggestion for array_search

Edit report at https://bugs.php.net/bug.php?id=55389&edit=1 ID: 55389 Updated by: cmb@php.net Reported by: pgreviews at gmail dot com Summary: Feature suggestion for array_search -Status: Open +Status: Feedback Type: Feature/Change Request Package: Arrays related Operating System: Ubuntu Linux PHP Version: Irrelevant Block user comment: N Private report: N New Comment: > 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?

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! -Scott (pgreviews@gmail.com) 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) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=55389&edit=1
