在使用foreach循環多維數組時使用名稱？

Question

我想做一個網站（不要問它是什麼），我需要幫助。 我創造了這個頁面調用meallist.php：

<?php 
/* Ingredients List */ 
$meatlist = array(tavuketi => "Tavuk Eti", 
        baliketi => "Balık Eti"); 

$vegelist = array(domates => "Domates", 
        patates => "Patates", 
        salatalik => "Salatalık"); 

/* The Meals - dun dun duuuunnnnnn */ 

$yemekaralist = array(mangaldatavuk => array(
              name => "Mangalda Tavuk", 
              ing1 => tavuketi), 
         mangaldapatateslitavuk => array( 
              name => "Mangalda Patatesli Tavuk", 
              ing1 => tavuketi, 
              ing2 => patates), 
         mangaldabalik => array(
              name => "Mangalda Balık", 
              ing1 => baliketi), 
         firindapatateslibalik => array(
              name => "Fırında Patatesli Balık", 
              ing1 => baliketi, 
              ing2 => patates)); 

?> 

你的想法。我做了一個的index.php foreach循環，創建一個選擇：

<div id="etler"> 
<select multiple="multiple" name="selectMeal[]" size="4" data-max-length="30"> 
<?php 
foreach($meatlist as $id => $name) 
{ 
    print "<option value=\"" . $id . "\">" . $name . "</option>"; 
} 

?> 
</select> 
</div> 
<div id="sebze"> 
<select multiple="multiple" name="selectMeal[]" size="4" data-max-length="30"> 
<?php 
foreach($vegelist as $id1 => $name1) 
{ 
    print "<option value=\"" . $id1 . "\">" . $name1 . "</option>"; 
} 

?> 
</select> 
</div> 

而且這職位selectMeal []，並得到其放入searchmeal.php $搜索。我想要的是，我希望它在meallist.php中搜索$ yemekaralist，並檢查ing1（和ing2是否可用），如果它與selectMeal []數組匹配，並且打印名稱=>「something」（如果可用）。我怎樣才能做到這一點？

你可以改變$結構yemekaralist？

如果你改變了結構，這樣的事情這將簡化你的算法：

$yemekaralist = array(
    item1 => array(
     'name' => 'item1_name', 
     'ingredients' => array('tavuketi', 'patates'), 
    ), 
    item2 => array(
     'name' => 'item2_name', 
     'ingredients' => array('tavuketi', 'patates'), 
    ), 

然後是這樣的：

foreach ($yemekaralist as $item) { 
    foreach ($item['ingredients'] as $ingredient) { 
     foreach ($selectMeal as $selectedMeal) { 
      if ($selectedMeal == $ingredient) { 
       echo $item['name']; 
      } 
     } 
    } 
}
