我正在寻找一种从数组中提取/获取值并将值分配给变量并获取所有值之和的方法。

更具体地说,用户将输入一组字母。如果存在匹配,将输入的字母将与现有数组的键进行比较。当数组中有匹配项时,键的对应值(具有匹配项)将分配给一个新变量,并计算值的总和(w/c 应为数字)。我一直在想办法解决这个问题,但由于经验不足,我还没有真正找到好的方法。

你们对此有什么想法吗?请问有什么建议吗?

以下是代码:

<?php
    class GreekNum
    {           
        public function setText($text)
        {
            $this->text=$text;
        }

        public function getText()
        {
            return $this->text;
        }       

        public function Convert($text)
        {

            $TextLength = strlen($text);
            $text = strtoupper($text);
            $text = str_split($text);       

            $collection = array(
                                    "A" => 1,
                                    "B" => 2,
                                    "G" => 3,
                                    "D" => 4,
                                    "E" => 5,
                                    "#" => 6,
                                    "Z" => 7,
                                    "Y" => 8,
                                    "H" => 9,
                                    "I" => 10,
                                    "K" => 20,
                                    "4" => 30,
                                    "M" => 40,
                                    "N" => 50,
                                    "X" => 60,
                                    "O" => 70,
                                    "P" => 80,
                                    "Q" => 90,
                                    "R" => 100,
                                    "S" => 200,
                                    "T" => 300,
                                    "U" => 400,
                                    "F" => 500, 
                                    "C" => 600,             
                                    "$" => 700,
                                    "W" => 800,
                                    "3" => 900, 
                                );

            if(isset($text))
            {
                $total = 0;
                for($i=0; $i<$TextLength; $i++)
                {
                    if(array_key_exists($text[$i], $collection))
                    {
                        $total += $text[$i];
                    }
                }
                return $total;

            }                   
        }

    }   

    $GreekNum = new GreekNum();

    $text = $_POST['text'];
    $GreekNum->setText($text);

    echo "<br>";
    echo "<b>Entered Values: </b><br>". $GreekNum->getText();
    echo "<br>";
    echo "<br>";

    echo "<b>Decimal Number Equivalence: </b><br/>". $GreekNum->Convert($text);



?>

对于看过这些代码的人来说,是的,我已经发布了它,因为我似乎找不到一个错误。我能够修复错误,但现在的问题是我无法真正获得所需的输出。请理解。谢谢。

如果您要获取输入的每个字母的值的总和,请替换为:

$total += $text[$i];

这样 :

$total += $collection[$text[$i]];
