Question

我输入textarea，我输入的文本转换为$array，如：

Array
(
    [0] => cat
    [1] => sat
    [2] => on
    [3] => the
    [4] => monkey
    [6] => is
    [7] => nice
    [8] => dog
    [9] => ate
    [10] => fish
)

我有$another_array喜欢：

Array
(
    [0] => Array
        (
            [id] => 1
            [word] => cat
            [keyword] => nice cat
        )

    [1] => Array
        (
            [id] => 2
            [word] => dog
            [keyword] => good dog
        )

    [2] => Array
        (
            [id] => 3
            [word] => monkey
            [keyword] => cute monkey
        )

    [3] => Array
        (
            [id] => 4
            [word] => fish
            [keyword] => fresh fish
        )

    [4] => Array
        (
            [id] => 5
            [word] => bird
            [keyword] => love bird
        )

    [5] => Array
        (
            [id] => 6
            [word] => rabbit
            [keyword] => rats
        )

    [6] => Array
        (
            [id] => 7
            [word] => animal
            [keyword] => not animal
        )

)

我要做的是替换$array中匹配$another_array中[word]的所有单词，并替换$another_array中基于[keyword]的textarea上的每个单词

我尝试使用str_replace，但结果太乱了。

我在textarea中输入的文字

cat sat on the monkey, monkey is nice, dog ate fish

我想要一个像

这样的结果

nice cat sat on the cute monkey, cute monkey is nice, good dog ate fresh fish

Answer 1

试用此代码

$check = [
    ["id"=>1, "word"=>"dog", "keyword"=>"good dog"],
    ["id"=>2, "word"=>"monkey", "keyword"=>"cute monkey"],
    ["id"=>3, "word"=>"fish", "keyword"=>"fresh fish"]
];


$input = [
           'dog',
           'sat',
           'monkey',       
           'fish'       
        ];


$result =   array_map(function ($v) use ($value, $check) {
                $key = array_search($v, array_column($check, 'word'));
                if(is_numeric($key)){
                    return $v = $check[$key]['keyword'];
                }

                return $v;
            }, $input);

print_r($result);

echo implode(" ",$result);

Answer 2

对于性能，您可以保存地图以避免每次都遍历另一个数组。你可以使用implode和explode来在字符串和数组之间进行转换。

$value_map = [];
foreach($another_array as $v)
{
  $value_map[$k['word']] = $v['keyword'];
}
$result = array_map(function($v) use($value_map){return isset($value_map[$v]) ? $value_map[$v] : $v;}, $array);

Answer 3

如果您没有获得任何选择，请尝试此操作。

$array = array
(
    0 => 'cat',
    1 => 'sat',
    2 => 'on',
    3 => 'the',
    4 => 'monkey',
    6 => 'is',
    7 => 'nice',
    8 => 'dog',
    9 => 'ate',
    10 => 'fish'
);

$anotherarray = array
(
    0 => array('id' => 1,'word' => 'cat','keyword' => 'nice cat'),
    1 => array('id' => 2,'word' => 'dog','keyword' => 'good dog'),
    2 => array('id' => 3,'word' => 'monkey','keyword' => 'cute monkey'),
    3 => array('id' => 4,'word' => 'fish','keyword' => 'fresh fish'),
    4 => array('id' => 5,'word' => 'bird','keyword' => 'love bird'),
    5 => array('id' => 6,'word' => 'rabbit','keyword' => 'rats'),
    6 => array('id' => 7,'word' => 'animal','keyword' => 'not animal')
);

$concat = implode(' ', $array);

echo $concat.'<br/>';

foreach ($array as $key1 => $item) 
{
    foreach ($anotherarray as $key2 => $search) 
    {
        if(in_array($item, $search))
        {
            $array[$key1] = $search['keyword'];
        }
    }
}

$concat = implode(' ', $array);

echo $concat;

Answer 4

试试这段代码，

foreach ($array as $k => $v) {
    if($a = array_search($v, array_column($another_array, 'word'))){
        $array[$k] = $another_array[$a]['keyword'];
    }
}
$str = implode(' ', $array);

试一试，这样可行。
