PHP：檢查，什麼陣列值大於1（複製等）

Question

有一個數組：

Array 
(
    [Apple] => 1 
    [Banana] => 2 
    [Orange] => 1 
    [Pie] => 3 
) 

我想檢查一下，有什麼陣列值大於1（副本等）並返回它們。

'Banana was found 2 times in the array, Pie even 3 times. 

Answer 1

您可以使用array_filter過濾基於鍵/值的數組。它只返回一個數組，其中只有匹配回調函數中的條件。

$greaterThanOne = array_filter($array, function($val){ return ($val > 1); }); 

foreach($greaterThanOne as $fruit=>$count){ 
    echo "$fruit was found $count times in the array.<br>"; 
} 

Answer 2

你只需要遍歷數組...

foreach ($array_with_fruits as $fruit=>$times){ 
    if ($times>1) { echo $fruit." was found ".$times." times"; } 
}
