Wie würde ich ein Array von Std-Class-Objekten nach spezifischer Listing-Reihenfolge sortieren?

Question

Ich habe eine Reihe von StdClass Objects und diese enthält verschiedene Car Typen (zB Compact Car, Minivan, etc.) sortiert nach Preis. Ich möchte das Array in der folgenden Reihenfolge sortieren:

• Economy Car
• Compact Car
• Mid-Size Car
• Standardgröße Auto
• Full-Size-Auto
• Premium- Auto
• Luxusauto
• Standardgröße Convertible
• Mid-Size SUV
• Standard-SUV
• Full-Size SUV
• Minivan
• Rest nach Preis sortiert Autos

Ich bin mir nicht sicher, ob es sinnvoll, diese zu sortieren macht Bestellung mit Schlüssel "Beschreibung" oder "Codes". Ich habe herausgefunden, wie man nach Preis sortiert, aber nicht sicher, wie man das Array in der oben genannten Reihenfolge neu anordnet. Jede Hilfe wäre willkommen. Vielen Dank!

Code:

usort($car_types,function($a,$b) { 
    return $a->price == $b->price ? 0 : $a->price > $b->price; 
}); 

usort($car_types, function($a, $b) use ($order) { 
    $a_set = intval(isset($order[$a->description])); 
    $b_set = intval(isset($order[$b->description])); 

    return $a_set === $b_set && $a_set === 1 
    ? $order[$a->description] - $order[$b->description] 
    : $b_set - $a_set; 
}); 

Answer 1

definiert Array Bestellung und es verwendet, innerhalb usort:

$order = [ 
    'Economy Car' => 1, 
    'Compact Car' => 2, 
    'Mid-Size Car' => 3, 
    'Standard-Size Car' => 4, 
    'Full-Size Car' => 5, 
    'Premium Car' => 6, 
    'Luxury Car' => 7, 
    'Standard-Size Convertible' => 8, 
    'Mid-Size SUV' => 9, 
    'Standard SUV' => 10, 
    'Full-Size SUV' => 11, 
    'Minivan' => 12 
]; 

usort($car_types, function ($a, $b) use ($order) { 
    static $notSetPriority; 

    $aPriority = isset($order[$a->description]) 
     ? $order[$a->description] 
     : $notSetPriority ?? ($notSetPriority = count($order) + 1); 
    $bPriority = isset($order[$b->description]) 
     ? $order[$b->description] 
     : $notSetPriority; 

    if (($comparison = $aPriority - $bPriority) === 0) { 
     return floatval($a->price) - floatval($b->price); 
    } 

    return $comparison; 
}); 

Wenn das Auftragsgewicht für die Beschreibung nicht ist setzen, dann geben wir ein Gewicht von den meisten w acht plus eins.

Wenden Sie die usort nicht mehr als einmal an, da es schwierig ist, das Ergebnis vorherzusagen. Ich habe beide Sortierkriterien zu einem zusammengefasst.
