遍歷一個數組，並檢查值中的一個是一個字符串

Question

我有

一個串$input =「約翰的一個加2」，和

一個陣列的一部分$devices

array:54 [ 
    0 => array:1 [ 
    "name" => "xperia-z-ultra"

我想

來循環訪問我的數組，然後檢查我的$input子字符串是否包含我的$devices數組的其中一個設備名稱。

---

我試圖

foreach ($devices as $i=>$device) { 
    if(stripos($input, $device['name']) !== false){ 
     dd('True'); 
    } 
    else 
     dd('False'); 

} 

---

我

False打印。儘管如此，我知道one-plus-2實際上存在於我的設備陣列中。

11 => array:1 ["name" => "one-plus-2"] 

我錯過了什麼嗎？

任何提示/建議，將非常感謝！

Answer 1

你交換針和乾草堆參數
本

if(stripos($device['name'], $input) !== false){ ...} 

Answer 2

嘗試你可以使用array_filter()與strpos()：

$matches = array_filter($devices, function($device) use ($input) { 
    return strpos($input, $device['name']) !== FALSE; 
}); 
dd($matches); 

array_filter()不重指數，所以第一個關鍵不是0，而是11（在這種情況下）。

Answer 3

stripos函數>>> strpos

「stripos函數」 錯正確的是 「strpos」

和參數必須

strpos（以搜索的字符串，你想要的字符串）

if (strpos($device['name'], $input) !== false) { 
    echo 'true'; 
}
