如何項的數組轉換爲自己的coressponding ID

Question

的陣列我有一個表，其中所含的成分如下我的MySQL數據庫：

id ingredient 

1 egg 
2 peanut 
3 treenut 
4 oil 

現在我有一個數組作爲配料= [花生，油，蛋]

我具有與本數組轉換爲相應的ID的數組如下：

成分= [2,4,1] 誰能幫助??

在此先感謝...

Answer 1

$ingridents = array("peanut", "oil", "eg"); 
$newArray = array(); 
$result = mysqli_query($link, "SELECT id, ingrident FROM ingridents WHERE ingrident IN (".implode(",", $ingridents).")"); 
while($row = mysqli_fetch_assoc($result) { 
    $newArray[$row['ingrident']] = $row['id']; 
} 

echo $newArray['peanut']; // would echo out the ID of peanut 

Answer 2

試試這個...

$ingredients = array("peanut", "oil", "egg"); 

$ingredients = "'".implode("','", $ingredients)."'"; 
$query = mysqli_query($link, "SELECT id, ingredient FROM table WHERE ingredient IN ($ingredients)"); 
while($row = mysqli_fetch_assoc($query) { 
    $ingredient_ids[] = $row['id']; 
}
