Question

当我尝试以下代码时，我只得到第一个输出。我想将所有输出附加到数组self::$results，以便相同的函数将返回该数组，但在运行脚本后，该函数返回数组但只返回第一个输出。这意味着，它只附加了第一个输出。

class book
{
    /**
     * @array static $alpha; holds array of accepted words
     */
    public static $alpha = array();
    /**
     * @array static $result; holds array of correct answers
     */
    public static $results;
    /**
     * @string protected $word; parametr
     */
    protected $word;
    /**
     * @var static $alpha; holder of class instance getter
     * returns self::getInstance
     */
    public static $init;

    /**
     * @method static getInstance(); class instance getter
     * returns self();
     */

    function __construct()
    {
       self::$alpha = array('love','life','health','power','money','God'); 
    } 

    public static function getInstance()
    {
        if (self::$init === null)
        {
            self::$init = new self();
            return self::$init;
        }
    }

    /**
     * @method static check()
     * takes 1 param; self::$word
     * returns bool
     */
    public static function check($word)
    {

        for($i=0;$i<=count(self::$alpha)-1;$i++)
        {
            if(similar_text($word,self::$alpha[$i]) === strlen($word))
            {
                return true;
            }

        }
    }





    /**
     * @method static result()
     * takes 1 param; self::check()
     * returns bool
     */
    public static function result($bool)
    {
        if($bool === true)
        {
            return 'correct';
        }
        else
        {
            return 'wrong';
        }
    }

    /**
     * @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;
        }
    }

}




$array = array('love','ama','kofi','money','health','God');
print_r(book::getInstance()->getter($array));
var_dump(book::check('love')) ;
?>

Answer 1

您在for循环中拥有return。这就是为什么当它第一次运行时，它会在那里返回函数，而不是继续循环。

将您的功能更改为此功能，它将按照您希望的方式运行：

/**
 * @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;
}

Answer 2

您从循环内部的$getter返回，因此在添加第一个元素后返回。你应该完成循环，然后返回：

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;
}

如何在同一个函数中为单个数组添加更多值？
