Unsetting an array in php

Question

I have a file called layout.php which contains

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

        "wXBMCLibrary" => array(
            "title" => "XBMC Library",
            "display" => ""
        ),
        "wRecentMovies" => array(
            "title" => "Recent Movies",
            "display" => ""
        ),
        "wRecentTV" => array(
            "title" => "Recent TV",
            "display" => ""
        )
    )
    );
?>

What I would like to be able to do is remove any part, for example if I say remove wXBMCLibrary it must remove all of the below

 "wXBMCLibrary" => array(
        "title" => "XBMC Library",
        "display" => ""
    ),

Is this at all possible? Would you be able to unset the whole piece? What would the coding be? Regards

You can't automatically remove all 'below' an element in PHP, but you can loop over the array and manually delete elements after finding the one you want. — Marc B

Could I use variables in place of 'section1' and 'wXBMCLibrary'

This is completely possible through the usage of unset() within PHP. The unset() function will remove the item that you specify, so if you specify unset($arrLayout['section1']['wXBMCLibrary']); then that will remove the array with the index of 'wXBMCLibrary'.
