Ищет значение в многомерном массиве в PHP

Question

У меня есть такой массив:

array(1) { 
    [36694730] => array(2) { 
     ["summonerId"] => int(36694730)

Я хочу увидеть, если элемент с определенным ключом «именем», (например, «Рвение ADC») существует в нем, чтобы использовать его для проверки членства. Как я могу найти его, зная, что массив может иметь больше значений? [0] до [4] здесь количество страниц и варьируется от 1 до 20.

Answer 1

// Воля познает значение существует или нет в массиве

echo in_array_r("Fervor ADC", $array) ? 'found' : 'not found'; 

// функции найти значение существуют или нет в массиве.

function in_array_r($needle, $haystack, $strict = false) { 
    foreach ($haystack as $item) { 
     if (($strict ? $item === $needle : $item == $needle) || (is_array($item) && in_array_r($needle, $item, $strict))) { 
      return true; 
     } 
    } 

    return false; 
} 

Answer 2

Инициализировать результат и поиск по ключевому слову

$result = null; 
$searchName = "Fervor ADC" 

Петля над значениями в «страницы» ключ:

foreach ($your_array['36694730']['pages'] as $x) { 

    // if you find one that matches your search term, set your result to that one 
    if ($x['name'] == $searchName) { 
     $result = $x; 

     // then stop the loop; you're done. 
     break; 
    } 
} 

Тогда, если вы просто хотите, чтобы убедиться, что она существует

if ($result) 

будет работать. И если вам в итоге нужно что-то сделать с данными, связанными с этим именем, тогда вы получите его в $result.
