php - add to deepest array child element -

-

how select deepest child element multidimensional-array in order add element specific 1 in php (always knowing added, in case additional information parent needed in order create new child)?

eg. having array want able add aaaa, bbbb, cccc each: aaa, bbb, ccc? , later on aaaaa, bbbbb,… each aaaa, bbbb… , on (where each new element aware of it's parent's name).

array( "a"=> array(     "aa"=> array(        "aaa",        "bbb",        "ccc"        ),     "bb"=> array(        "aaa",        "bbb",        "ccc"        ),     "aa"=> array(        "aaa",        "bbb",        "ccc"        ),     ), "b"=> array(     "aa"=> array(        "aaa",        "bbb",        "ccc"        ),     "bb"=> array(        "aaa",        "bbb",        "ccc"        ),     "aa"=> array(        "aaa",        "bbb",        "ccc"        ),     ), "c"=> array(     "aa"=> array(        "aaa",        "bbb",        "ccc"        ),        […]     ), );

you might want use array_walk_recursive. lets itterate on leafs of multidimensional array.

function add_children(&$item, $key) {     //here can change item else (since use &)     $item = array('aaaa', 'bbbb', 'cccc'); }  array_walk_recursive($array, 'add_children');

disclaimar: have not tested code.
