PHP：按照另一个数组中的字母顺序对数组进行排序

Question

I'm making a little hangman game, and I want to sort the guesses the person makes in order of the actual word; Here is my code:

$word = "peach";
$_SESSION['letters'] = str_split($word);

ˆThat is where I make the word into an array, and I want when correct letters are added to an array, that they be sorted in order of the word. Is there any way I could do this, or another way I could write it? Thank you for your help.

Answer 1

I misunderstood. Try this:

<?php
$guess = 'reach';
$guess_array = str_split($guess);
$word = 'peach';
$word_array = str_split($word);

$result = '';
foreach($word_array as $letter)
{
    if(in_array($letter, $guess_array))
    {
        $result .= $letter;
    }
    else
    {
        $result .= '_';
    }
}
echo($result);
// outputs: "_each"
?>
