PHP - 按大小写单词拆分数组

Question

我有这个数组

$arr2 = array("SUBTITLE", "Test Your Might RUNTIME", "1 hr 41 mins GENRE", "Science-Fiction/Fantasy SYNOPSIS", "his film adaptation of the wildly popular video game comes complete with dazzling special effects and plenty of martial arts action. LIGTHNING AND EFFECT")

我想将所有大写的单词与小写的句子分开。像这样。

$arr2 = array("SUBTITLE", "Test Your Might", "RUNTIME", "1 hr 41 mins", "GENRE", "Science-Fiction/Fantasy", "SYNOPSIS", "his film adaptation of the wildly popular video game comes complete with dazzling special effects and plenty of martial arts action.", "LIGHTNING AND EFFECT")

我该怎么做？如果有办法用正则表达式做到这一点，那将是首选。感谢您的帮助。

Answer 1

每当有变化时，我都会使用分隔符来加入案例。我不知道您还可以传递什么其他类型的数据，所以我将分隔符作为一个变量保留，以便轻松更改。

$separator = '<br>';

foreach($arr2 as $index => $str) {
  $str = explode(" ", $str);
  $final_string = '';
  $last_case = '';

  foreach($str as $word) {
    if ($word === strtoupper($word)) {
      if ($last_case == 'lower') $final_string .= $separator.$word;
      else $final_string .= $word . ' ';

      $last_case = 'upper';
    } else {
      if ($last_case == 'upper') $final_string .= $separator.$word;
      else $final_string .= $word . ' ';

      $last_case = 'lower';
    }
  }

  $arr2[$index] = explode($separator, trim($final_string));
}

$arr2 = array_reduce($arr2, 'array_merge', []);

print_r($arr2); // array ( 0 => 'SUBTITLE', 1 => 'Test Your Might ', 2 => 'RUNTIME', 3 => '1 hr 41 mins', 4 => 'GENRE', 5 => 'Science-Fiction/Fantasy', 6 => 'SYNOPSIS', 7 => 'his film adaptation of the wildly popular video game comes complete with dazzling special effects and plenty of martial arts action.', 8 => 'STARRING');

Answer 2

我会这样做：

<?php
$a = ['SUBTITLE', 'Test Your Might RUNTIME', '1 hr 41 mins GENRE', 'Science-Fiction/Fantasy SYNOPSIS', 'his film adaptation of the wildly popular video game comes complete with dazzling special effects and plenty of martial arts action. LIGTHNING AND EFFECT'];
foreach($a as $v){
  if(preg_match('/(?:[A-Z]{2,}(?:\s+|$))+/', $v, $m)){
    foreach($m as $s){
      if($s === $v){
        $r[] = $s;
      }
      else{
        $r[] = str_replace($s, '', $v); $r[] = $s;
      }
    }
  }
  else{
    $r[] = $v;
  }
}
print_r($r);
?>

请确认它按预期工作，但一种方法是执行以下操作：

function splitter($jumbled) {
  $lowercase = [];
  foreach($jumbled as $element){
    $exploded = explode(" ", $element);
    foreach ($exploded as $word){
      if ($word == strtoupper($word)){
        $uppercase[] = $word;
      } else {
        $lowercase .= $word . ' ';
      }
    }
    $output[] = $uppercase;
    $output[] = rtrim($lowercase,' ');
  }
 return $output;
}

然后用 arr2 调用函数：splitter($arr2)

（注意：这会根据您的要求返回数组，但如果您将相应的值匹配为正在返回的数组中的 $uppercase => $lowercase 键/值对，则使用数组后缀会更容易）
