使用2个自定义条件对多维关联数组进行排序:(按星期几和膳食时间计量）

Question

I have a multidimensional array which needs to be sorted by two custom criteria in order:

1. Day of Week
2. Meal of Day (breakfast/lunch/dinner)

Documentation of array_multisort() and uksort() have gotten me half way there each, but I am unable to put it all together meaningfully. Thank you for your time

Array
(
    [name] => hashbrowns
    [day] => monday
    [mealTime] => breakfast
)
Array
(
    [name] => Steak
    [day] => monday
    [mealTime] => dinner
)
Array
(
    [name] => Avacados
    [day] => tuesday
    [mealTime] => dinner
)
Array
(
    [name] => Peaches
    [day] => tuesday
    [mealTime] => lunch
)
Array
(
    [name] => Sammich
    [day] => monday
    [mealTime] => lunch
)
Array
(
    [name] => Kale & Sadness
    [day] => tuesday
    [mealTime] => breakfast
)

Desired output example:

Array
(
    [name] => hashbrowns
    [day] => monday
    [mealTime] => breakfast
)
Array
(
    [name] => Sammich
    [day] => monday
    [mealTime] => lunch
)
Array
(
    [name] => Steak
    [day] => monday
    [mealTime] => dinner
)
Array
(
    [name] => Kale & Sadness
    [day] => tuesday
    [mealTime] => breakfast
)
Array
(
    [name] => Peaches
    [day] => tuesday
    [mealTime] => lunch
)
Array
(
    [name] => Avacados
    [day] => tuesday
    [mealTime] => dinner
)

Answer 1

try this solution. Surely it can be done with php functions but what happened to you seems to work.

$data = array(
array("name" => "Otra cosa","day" => "thursday","mealTime" => "dinner"),
array("name" => "hashbrowns","day" => "monday","mealTime" => "breakfast"),
array("name" => "Steak","day" => "monday","mealTime" => "dinner"),
array("name" => "Avacados","day" => "tuesday","mealTime" => "dinner"),
array("name" => "Cuchu","day" => "monday","mealTime" => "breakfast"),
array("name" => "Avacados 2","day" => "monday","mealTime" => "lunch"));



$day = array("monday" => 0, "tuesday" => 1, "wednesday" => 2, "thursday" => 3, "friday" => 4, "saturday" => 5, "sunday" => 6);
$mealTime = array("breakfast" =>0, "lunch" =>1, "dinner" => 2);


$result = array();

foreach($data as $values) {
    $d = $day[$values["day"]];
    $mt = $mealTime[$values["mealTime"]];
    if(!isset($result[$d])) {
        $result[$d] = array();
    }
    if(!isset($result[$d][$mt])) {
        $result[$d][$mt] = array();
    }

    $result[$d][$mt][] = $values;
    ksort($result[$d]);

}
ksort($result);
$_result = array();

foreach($result as $r) {
    foreach($r as $_r) {
        foreach($_r as $__r) {
            $_result[] = $__r;
        }
    }
}

return $_result;

//print_r("<pre>");
//print_r($_result);
//print_r("</pre>");
