  • convert array keys to paths

    From alex@21:1/5 to All on Mon Jun 28 12:57:14 2021
    Look at this array

    array (
    'a' =>
    array (
    'b1' =>
    array (
    'c1' => 1,
    'c2' => 2,
    'c3' => 3,
    ),
    'b2' =>
    array (
    'c' => 4,
    ),
    ),
    )

    You can convert it to

    array (
    'a/b1/c1' => 1,
    'a/b1/c2' => 2,
    'a/b1/c3' => 3,
    'a/b2/c' => 4,
    )

    Possibly without using a complex set of instructions:
    foeach, array_map (), etc.

    A little bit of complexity may be needed.

    I came up with:

    function pathjoin_help($o, $elms, &$res) {
    if(is_int($o)) {
    $res[implode('/', $elms)] = $o;
    } else if(is_array($o)) {
    $elms[] = null;
    foreach($o as $pathelm => $value) {
    $elms[count($elms)-1] = $pathelm;
    pathjoin_help($value, $elms, $res);
    }
    } else {
    die("Houston we have a problem");
    }
    }

    function pathjoin($a) {
    $res = array();
    pathjoin_help($a, array(), $res);
    return $res;
    }

    You changed:

    'c1' => 1

    to:

    'c1' => '1'

    and my code required integer.

    If you want the final item to be anything then you can use:

    function pathjoin_help($o, $elms, &$res) {
    if(is_array($o)) {
    $elms[] = null;
    foreach($o as $pathelm => $value) {
    $elms[count($elms)-1] = $pathelm;
    pathjoin_help($value, $elms, $res);
    }
    } else {
    $res[implode('/', $elms)] = $o;
    }
    }
