在 PHP 中搜索并返回从数组值中匹配的子字符串 - Search and Return Matched Substrings from Array Values in PHP

Search and Return Matched Substrings from Array Values in PHP

本文关键字：字符串搜索 PHP 返回数组 | 更新日期: 2023-09-27

我有一个这样的数组：

0 => dsadjdasActionsdadas | 123 4Dramdsadsa
1 => dsakjdsa Crime dasdsadas Sci-Fci
2 => dasjhdashkAdventuredsadsasa

我想修剪除"动作"、"德拉姆"、"犯罪"、"科幻"、"冒险"和"|"之外的所有内容，以将数组的键值更改为类似的东西。它必须区分大小写。

0 => Action | Dram
1 => Crime | Sci-Fci
2 => Adventure

具有

preg_match_all、array_map和implode函数的简单解决方案：

$arr = [
    0 => 'dsadjdasActionsdadas | 123 4Dramdsadsa',
    1 => 'dsakjdsa Crime dasdsadas |Sci-Fci',
    2 => 'dasjhdashkAdventuredsadsasa'
];
$result = array_map(function($v){
    preg_match_all("/(Action|Dram|Crime|Sci-Fci|Adventure|'|)+?/", $v, $matches);
    return implode(' ',$matches[0]);
}, $arr);

var_dump($result);
// the output:
array (size=3)
  0 => string 'Action | Dram' (length=13)
  1 => string 'Crime | Sci-Fci' (length=15)
  2 => string 'Adventure' (length=9)

我希望这对你有帮助

$array = array("dsadjdasActionsdadas | 123 4Dramdsadsa", "dsakjdsa Crime | dasdsadas Sci-Fci", "dasjhdashkAdventuredsadsasa");
print_r($array);
$clean_array = array_map('cleanGenre', $array);
print_r($clean_array);
function cleanGenre($text)
{
    $genres = array('Action', 'Adventure', 'Crime', 'Dram', 'Sci-Fci');
    $parts = explode("|", $text);
    $result = array();
    foreach($parts as $part)
        foreach($genres as $genre)
            if (preg_match("/". $genre. "/i", $part))
                $result[] = $genre;
    return (implode(' | ', $result));
}

结果将是：

Array
(
    [0] => dsadjdasActionsdadas | 123 4Dramdsadsa
    [1] => dsakjdsa Crime | dasdsadas Sci-Fci
    [2] => dasjhdashkAdventuredsadsasa
)
Array
(
    [0] => Action | Dram
    [1] => Crime | Sci-Fci
    [2] => Adventure
)

请注意，我在$array[1]中插入了一个"|"符号。
