如何搜索多維數組中的值

Question

我有一個動態數組。我想搜索是否有任何值「雕刻」，然後它應該返回true。 我如何能實現像下面

Array 
(

     (
      [product_option_id] => 2222

Answer 1

您可以使用一個遞歸函數在多維數組陣列搜索。

function in_array_recursive($needle, $haystack) { 
    foreach ($haystack as $value) { 
     if ($needle == $value) return true; 
     if (is_array($value) && in_array_recursive($needle, $value)) return true; 
    } 
    return false; 
} 

$found = in_array_recursive('Engraving', $your_array); 

---

上述功能將只匹配整個值。如果您需要匹配部分字符串，則需要添加strpos檢查（謝謝，AbraCadaver）。

function in_array_recursive($needle, $haystack) { 
    foreach ($haystack as $value) { 
     if (is_array($value)) { 
      if (in_array_recursive($needle, $value)) return true; 
     } else { 
      if (strpos($value, $needle) !== false) return true; 
     } 
    } 
    return false; 
} 

$found = in_array_recursive('Engraving', $your_array);
