Question

问题很简单。我做错了什么，但我找不到解决方案。我错过了什么吗？

function harveyScrabble($mot){
    $worth10Points = array("y","Y");
    $worth5Points = array("v","V");
    $worth3Points = array("h","H");
    $worth2Points = array("r","R");
    $worth1Point = array("a","A","b","B","c","C","d","D","e","E","f","F","g","G","i",
                         "I","j","J","k","K","l","L","m","M","n","N","o","O","p","P",               
                         "q","Q","s","S","t","T","u","U","w","W","x","X","z","Z");

    $total = 0;
    for ($i=0; $i <count($mot) ; $i++) {
        $char = $mot{i};
        if (in_array($char, $worth10Points)) {
            $total += 10;
        }
        elseif (in_array($char, $worth5Points)) {
            $total += 5;
        }
        elseif (in_array($char, $worth3Points)) {
            $total += 3;
        }
        elseif (in_array($char, $worth2Points)) {
            $total += 2;
        }
        else{
            $total += 1;
        }
    }
    return $total;
}

当我尝试使用“Harambe”这个单词调用该函数时，它只给我3分。

Answer 1

您需要更改

for ($i=0; $i <count($mot) ; $i++) {

到

for ($i=0; $i <strlen($mot) ; $i++) {

Count用于计算数组中的元素（或对象中的可计数项），strlen将计算字符串中的字符数。

你也可以像这样循环这个词：

foreach(str_split($mot) as $letter){
  echo "$letter ";
}

此外，你应该多玩一些阵列。如果您学习如何使用它们，您可以显着缩短代码。

function harveyScrabble($word){
    $word   = strtolower($word);
    $total  = 0;
    $points = ['y' => 10, 'v' => 5, 'h' => 3, 'r' => 2];

    foreach(str_split($word) as $letter){
      if(isset($p = $points[$letter])){
        $total += $p;
      } else {
        $total += 1;
      }
    }

    return $points;
}
