Erhalte ein bestimmtes Objekt aus einem multidimensionalen Array

Question

Ich kämpfe um das bestimmte Element aus dem folgenden Array zu bekommen. Ich möchte den 2. Gegenstand vom 3., 10. und 17. Nummernfeld erhalten. Wenn ich mehr Objekte in dem Array habe, wird es kontinuierlich das zweite Objekt in einem Muster finden.

Ich bin jedoch nicht in der Lage, das 2. Element von der Verwendung des obigen Musters zu bekommen, und ich bekomme keine Logik, um dies zu bekommen.

Was soll ich in diesem Fall tun? Hast du irgendeine Logik? Wie würden Sie alle Arrays überspringen und nur bestimmte Elemente zurückgeben?

Answer 1

SET $array als Ihr multidimensionales Array.

Schleife durch das Array

$list = array('3', '10', '17'); 
foreach($array as $key => $a) { 
    if (in_array($key, $list) || ($key > 17 && array_key_exists('2', $a))) { 
     // You can get the value in here 
     echo "The 'specific' element in the array"; 
    } 
} 

Answer 2

Wenn Sie nur den 2 Index wollen (es wird nicht die „zweite“ sein als zweite beliebige Zahl sein könnte) von den Unteranordnungen dann:

$twos = array_column($array, 2); 

foreach($twos as $value) { 
    echo $value; 
}
