Question

我正在使用下面的代码，但我需要输出我的一些j son格式，如同Excepted output下面你能帮我解决一下我是怎么做到的，或者让我知道我在这里做错了什么

<?php
$text = "A very nice únÌcÕdë text. Something nice to think Something about if you're into Unicode.";
$words = str_word_count($text, 1); // use this function if you only want ASCII
$frequency = array_count_values($words);
arsort($frequency);
print_r($frequency);
?>


**Current output** 
   Array
(
    [nice] => 2
    [Something] => 2
    [A] => 1
    [very] => 1
    [n] => 1
    [c] => 1
    [d] => 1
    [text] => 1
    [to] => 1
    [think] => 1
    [about] => 1
    [if] => 1
    [you're] => 1
    [into] => 1
    [Unicode] => 1
)

**Excepted output Below :**

{
    {
        ‘word’ : ‘nice’
        ‘count’ : 2
        ‘rank’ : 1
     },
    {              
        ‘word’ : ‘Something’
        ‘count’ : 2
        ‘rank’ : 2
    },
    {              
        ‘word’ : ‘A’
        ‘count’ : 1
        ‘rank’ : 3
    }
}

and so on ... etc

Answer 1

我认为这就是你想要的。我使用 $ frequency

创建了新数组

$text = "A very nice únÌcÕdë text. Something nice to think Something about if you're into Unicode.";
$words = str_word_count($text, 1); // use this function if you only want ASCII
$frequency = array_count_values($words);
arsort($frequency);

$new_arr = array();

$rank_counter = 1;
foreach ($frequency as $key => $value) {
    $new_arr[] = array(
        'word' => $key,
        'count' => $value,
        'rank' => $rank_counter++,
    )
}

$myJSON = json_encode($new_arr);
echo "<pre>";
print_r($myJSON);

输出

[
    {
        word: "nice",
        count: 2,
        rank: 1
    },
    {
        word: "Something",
        count: 2,
        rank: 2
    },
    {
        word: "A",
        count: 1,
        rank: 3
    },
    {
        word: "very",
        count: 1,
        rank: 4
    },
    {
        word: "n",
        count: 1,
        rank: 5
    },
    {
        word: "c",
        count: 1,
        rank: 6
    },
    {
        word: "d",
        count: 1,
        rank: 7
    },
    {
        word: "text",
        count: 1,
        rank: 8
    },
    {
        word: "to",
        count: 1,
        rank: 9
    },
    {
        word: "think",
        count: 1,
        rank: 10
    },
    {
        word: "about",
        count: 1,
        rank: 11
    },
    {
        word: "if",
        count: 1,
        rank: 12
    },
    {
        word: "you're",
        count: 1,
        rank: 13
    },
    {
        word: "into",
        count: 1,
        rank: 14
    },
    {
        word: "Unicode",
        count: 1,
        rank: 15
    }
]
