php - 新分块的不同字符串长度元素数组中缺少一些数组元素

Question

我正在尝试将字符串数组转换为新的字符串数组，通过相应地附加同级项来更改每个元素的字数。但是我遇到的问题是先前数组的某些部分没有按要求进行转换。

到目前为止，这是我的代码：

$text_array = ['He needs to cultivate in order', 
'to be at the fourth level of the', 
'Martial Body Stage. Does he have inner energy?"', 
'Everyone jeered, laughed, and taunted.', 
'Qin Yun turned deaf ear to their taunts.',  
'His eyes were filled with sincerity as he',  
'looked at Yang Shiyue and said, "Teacher,', 
'I only formed my elemental energy this morning.', 
'I still not familiar with the control of', 
'my elemental energy and inner energy."',  
'After the empress heard the jeers from the',  
'crowd, she let out a sigh of relief and',  
'sneered, "This is only a little bit of',  
'inner Qi that you forced out.', 
'You have not yet stepped',  
'into the fourth level',  
'of the Martial Body realm and have no',  
'chance of breaking through. embarrass yourself!'];

        $last_converted_index = 0;
        $new_string_array = [];
        $single_valid_length_string = '';
        foreach (array_slice($text_array, $last_converted_index) as $item) {

            if (str_word_count($single_valid_length_string . $item) < 30) {

                $single_valid_length_string .= $item . ' ';
                $last_converted_index++;

            } else {
                $new_string_array[] = $single_valid_length_string."<br><br>";
                $single_valid_length_string = '';
            }

        }

        echo implode($new_string_array);

我目前得到的输出是：

He needs to cultivate in order to be at the fourth level of the Martial Body Stage. Does he have inner energy?" Everyone jeered, laughed, and taunted.

His eyes were filled with sincerity as he looked at Yang Shiyue and said, "Teacher, I only formed my elemental energy this morning.

my elemental energy and inner energy." After the empress heard the jeers from the crowd, she let out a sigh of relief and 

我的预期结果将是：

He needs to cultivate in order to be at the fourth level of the Martial Body Stage. Does he have inner energy?" Everyone jeered, laughed, and taunted.

His eyes were filled with sincerity as he looked at Yang Shiyue and said, "Teacher, I only formed my elemental energy this morning.

my elemental energy and inner energy." After the empress heard the jeers from the crowd, she let out a sigh of relief and 

sneered, "This is only a little bit of inner Qi that you forced out.You have not yet stepped into the fourth level

of the Martial Body realm and have no chance of breaking through. embarrass yourself!

任何帮助，将不胜感激。

如果您尝试将 的元素重新组织$text_array为具有不同的字长，最简单的解决方案是创建一个包含所有单词的数组（通过将现有字符串重新组合成一个然后再次拆分），然后array_chunk使用把它分成几组n词。例如：

function change_words_length($text, $numwords) {
    $words = explode(' ', implode(' ', $text));
    $output = array();
    foreach (array_chunk($words, $numwords) as $array) {
        $output[] = implode(' ', $array);
    }
    return $output;
}

print_r(change_words_length($text_array, 10));
print_r(change_words_length($text_array, 30));

输出：

Array
(
    [0] => He needs to cultivate in order to be at the
    [1] => fourth level of the Martial Body Stage. Does he have
    [2] => inner energy?" Everyone jeered, laughed, and taunted. Qin Yun turned
    [3] => deaf ear to their taunts. His eyes were filled with
    [4] => sincerity as he looked at Yang Shiyue and said, "Teacher,
    [5] => I only formed my elemental energy this morning. I still
    [6] => not familiar with the control of my elemental energy and
    [7] => inner energy." After the empress heard the jeers from the
    [8] => crowd, she let out a sigh of relief and sneered,
    [9] => "This is only a little bit of inner Qi that
    [10] => you forced out. You have not yet stepped into the
    [11] => fourth level of the Martial Body realm and have no
    [12] => chance of breaking through. embarrass yourself!
