How to take a single record from an array - php

Question

I have a function that counts the number of points for each letter. I want her to count the points for each word. See this is my code:
function getValue() {
$letter = $this->getName(); // String from FORM
// Switch looks at a letter and assigns the value points for that letter
switch(true){
case($letter == 'a'||$letter == 'e'||$letter == 'i'||$letter == 'o'||$letter == 'u'||$letter == 'l'||$letter == 'n'||$letter == 's'||$letter == 't'||$letter == 'r'):
return 1;
case($letter == 'd'||$letter == 'g'):
return 2;
case($letter == 'b'||$letter == 'c'||$letter == 'm'||$letter == 'p'):
return 3;
case($letter == 'f'||$letter == 'h'||$letter == 'v'||$letter == 'w'||$letter == 'y'):
return 4;
case($letter == 'k'):
return 5;
case($letter == 'j'||$letter == 'x'):
return 8;
case($letter == 'q'||$letter == 'z'):
return 10;
default:
return 0;
}
}
function makeWordsPoint() {
$total_word_points = 0;
$words = $this->word_for_letters;
foreach ($words as $word) {
$total_word_points = $word->getValue();
}
echo $word . "=" . $total_word_points
}
How I can do it? Thanks for help
EDIT:
Okey, look now. There is my two classes Word and Letter
<?php
class Word
{
private $word;
private $words_with_points = array();
function __construct($user_letters)
{
$this->word = $user_letters;
// creates array of object word for letters
$this->word_for_letters = $this->makeWordForLetters();
// creates array of letter objects for the word
$this->words_with_points = $this->makeWordsWithPoints();
}
function makeWordForLetters()
{
$word_objects = array();
$word = $this->getWord();
$file = file_get_contents( __DIR__."/../src/dictionary.txt");
$items = explode("\n", $file);
$letters = str_split($word);
foreach ($items as $item) {
$list = $letters;
// remove the original word (once)
$thisItem = preg_replace("/$word/", '', $item, 1);
for ($i = 0; $i < strlen($thisItem); $i++) {
$index = array_search($thisItem[$i], $list);
if ($index === false) {
continue 2; // letter not available
}
unset($list[$index]); // remove the letter from the list
}
array_push($word_objects, $item);
}
return $word_objects; // passed!
}
function makeWordsWithPoints()
{
$word = $this->makeWordForLetters();
$letter_objects = array();
foreach ($word as $character) {
array_push($letter_objects, new Letter($character));
}
return $letter_objects;
}
function getWord()
{
return $this->word;
}
function getWordForLetters()
{
return $this->word_for_letters;
}
function getWordsWithPoints()
{
return $this->words_with_points;
}
}
?>
<?php
class Letter
{
private $name;
private $value;
function __construct($letter)
{
$letter = strtolower($letter);
$this->name = $letter;
$this->value = $this->setValue();
}
function getName()
{
return $this->name;
}
function getValue()
{
return $this->value;
}
function setValue()
{
$letter = $this->getName();
switch(true){
case($letter == 'a'||$letter == 'e'||$letter == 'i'||$letter == 'o'||$letter == 'u'||$letter == 'l'||$letter == 'n'||$letter == 's'||$letter == 't'||$letter == 'r'):
return 1;
case($letter == 'd'||$letter == 'g'):
return 2;
case($letter == 'b'||$letter == 'c'||$letter == 'm'||$letter == 'p'):
return 3;
case($letter == 'f'||$letter == 'h'||$letter == 'v'||$letter == 'w'||$letter == 'y'):
return 4;
case($letter == 'k'):
return 5;
case($letter == 'j'||$letter == 'x'):
return 8;
case($letter == 'q'||$letter == 'z'):
return 10;
default:
return 0;
}
}
}
?>
And now when I write in now letters like this: loso function makeWordForLetters() search in my array correctly words for this letters and I display this words with points by makeWordsWithPoint like this:
l - 1
lo - 0
loo - 0
loos - 0
los - 0
oslo - 0
s - 1
solo - 0
But as you can see the score is incorrect because it displays the result for a single letter and not for a word.
How can I solve this problem?

Answer 1

take it as string, then use preg_split function, count new array length.eg:
$string="php教程#php入门:教程#字符串:多分隔符#字符串:拆分#数组";
$arr = preg_split("/(#|:)/",$string);
print_r($arr);

Answer 2

Try this code instead. I think it's cleaner.
<?php
// set the score of each char into array
const SCORES = [
// 1
'a'=> 1,
'e' => 1,
'i' => 1,
'o' => 1,
'u' => 1,
'l' => 1,
'n' => 1,
's' => 1,
't' => 1,
'r' => 1,
// 2
'd'=> 2,
'g'=> 2,
// 3
'b'=> 3,
'c'=> 3,
'm'=> 3,
'p'=> 3,
// 4
'f'=> 4,
'h'=> 4,
'v'=> 4,
'w'=> 4,
'y'=> 4,
// 5
'k'=> 5,
// 8
'j'=> 8,
'x'=> 8,
// 10
'q'=> 10,
'z'=> 10,
];
$word = 'abcdef'; // get the string from the request here
# print_r($word);
$chars = str_split($word); // split string into array of chars
# print_r($chars);
$scores = array_map(function($char) { // create a scores array that convert char into value
return SCORES[strtolower($char)] ?? 0; // get the score of each char and set to the array, if not exist set to 0
}, $chars);
# print_r($scores);
$totalScore = array_sum($scores); // get the sum of the scores
echo $word . "=" . $totalScore;
Let me know if you have any question.
