Question

I have multiple arrays shown below.

<?php
$arrLayout = array(
    "section1" => array(

        "wXBMCLibrary" => array(
            "title" => "XBMC Library",
            "display" => ""
        ),
        "wRecentMovies" => array(
            "title" => "Recent Movies",
            "display" => ""
        )
    ),
    "section2" => array(
        "wComingEpisodes" => array(
            "title" => "Coming Episodes",
            "display" => ""
        ),
        "wSearch" => array(
            "title" => "Search",
            "display" => ""
        )
    ),
 );

From looking at the code I can see that wXBMCLibrary comes from within section1. Is there a way to check via php which section each thing comes from? So if I moved wXBMCLibrary to section 2 and reran the code it would show that it is now in section 2. Hope that makes sense.

I want to

if ( $wXBMCLibrary == "false" )
{ 
unset($arrLayout['section1']['wXBMCLibrary']);
}

This all works perfectly except that wXBMCLibrary could be in section2 because it dynamically moves so the section1 part in the unset function isn’t accurate. I need a way to check which section it is in so that I can replace section1 with a variable defining the current section.

Thanks

Answer 1

function which_section($array, $find) {
  foreach ($array as $key => $value)
    foreach ($value as $k => $v)
      if ($k == $find) return $key;
  return false;
}

$section = which_section($arrLayout, 'wXBMCLibrary');
unset($arrLayout[$section]['wXBMCLibrary']);
