如何获取 [ATTACHMENT][/ATTACHMENT] 之间的字符串内容并转换为带有 js 方法和 PHP 方法的数组？

    例如，使用 PHP，您可以这样做：

    $str = 'Здесь аудио и фото[ATTACHMENT]jpg/c2cbd77405f5802457bff4ff07c23cc76a6ca4f9291ef99b23bd0570dc23de30/1572189798_7c3bb82d9ace96a798ca.jpg[/ATTACHMENT][ATTACHMENT]mp3/f97aa34259401559d4592f42f5a0b04a162f1c46b05f4c17e5cb79ee0a3ccd94/abba_-_happy-new-year.mp3[/ATTACHMENT]';

$arr = [];
! preg_match_all('~\[ATTACHMENT]\K[^[]+(?=\[/ATTACHMENT])~', $str, $arr) ?: $arr = $arr[0];

var_export($arr);

    结果：

    array (
  0 => 'jpg/c2cbd77405f5802457bff4ff07c23cc76a6ca4f9291ef99b23bd0570dc23de30/1572189798_7c3bb82d9ace96a798ca.jpg',
  1 => 'mp3/f97aa34259401559d4592f42f5a0b04a162f1c46b05f4c17e5cb79ee0a3ccd94/abba_-_happy-new-year.mp3',
)

    UPD：使用 JS，您可以这样做：

    let str = 'Здесь аудио и фото[ATTACHMENT]jpg/c2cbd77405f5802457bff4ff07c23cc76a6ca4f9291ef99b23bd0570dc23de30/1572189798_7c3bb82d9ace96a798ca.jpg[/ATTACHMENT][ATTACHMENT]mp3/f97aa34259401559d4592f42f5a0b04a162f1c46b05f4c17e5cb79ee0a3ccd94/abba_-_happy-new-year.mp3[/ATTACHMENT]';
let re = /(?<=\[ATTACHMENT])[^[]+(?=\[\/ATTACHMENT])/g;
let myArray = str.match(re);

console.log( myArray );
