Question

是否有任何现成的购买力平价功能,通过这种功能,我可以计算字母缩略语中字母的指数。

<?php
$a = "testword";
echo "Count of Characters is: " . strlen($a); 
?>

我现在想得到这个词的累积“总数”。

e.g.

A is the first letter of the alphabet so it maps to 1
B is the second letter of the alphabet so it maps to 2
C is the third letter of the alphabet so it maps to 3
D is the fourth letter of the alphabet so it maps to 4

因此,ABCD的字句 1+2+3+4=10

同样,我需要的是“前言”或任何字。

Answer 1

function WordSum($word)
{
    $cnt = 0;
    $word = strtoupper(trim($word));
    $len = strlen($word);

    for($i = 0; $i < $len; $i++)
    {
        $cnt += ord($word[$i]) - 64; 
    }

    return $cnt;
}

var_dump(WordSum("testword"));

Answer 2

仅表明一种完全不同的方法,因为她很乐意展示一些PHP阵列功能:

$data = "testword";

$testResult = array_values(array_merge(array_fill_keys(range( A , Z ),
                                                       0
                                                      ),
                                       array_count_values(str_split(strtoupper($data)
                                                                   )
                                                         )
                                      )
                          );
$wordCount = 0;
foreach($testResult as $letterValue => $letterCount) {
    $wordCount += ++$letterValue * $letterCount;
}

var_dump($wordCount);
