如何在同一個函數中爲單個數組添加更多值？

Question

當我嘗試下面的代碼時，我只得到第一個輸出。我想所有的輸出追加到數組self::$results使同一函數將返回數組，但在運行腳本後，該函數返回數組，但只有第一個輸出。這意味着，它只附加第一個輸出。

Answer 1

你從$getter返回循環中，所以添加的第一個元素後返回。你應該完成循環，然後返回：

public static function getter($array) 
{ 
    self::$results = array(); 
    for($i = 0;$i<=count($array)-1;$i++) 
    { 
     self::$results[] = self::result(book::check($array[$i])); 
    } 
    return self::$results; 
} 

Answer 2

您在for循環中有您的return。這就是爲什麼當它經歷了第一次，它返回的功能，而不是繼續循環。

你的函數改成這樣，它會工作，你如何想它：

/** 
* @method static getter() 
* takes 1 param; array of words to be searched 
* returns array self::$results 
*/ 
public static function getter($array) 
{ 
    self::$results = array(); 


    for($i = 0;$i<=count($array)-1;$i++) 
    { 


     // i want to add more thn one answers to to $result array but i get only the first answer. 
     //how do i ddo it? 
     self::$results[] = self::result(book::check($array[$i])); 
    } 

    return self::$results; 
}
