如何修改SQL文件的每一行

Question

我需要修改许多 SQL 语句以包含一个递增的数字来跟踪“段落”列中的每个单词。抱歉，我的 PHP 技能有限。阅读文件后，我正在考虑一个 foreach 循环，但无法提出任何实际修改行以包含每个单词的值的方法。

当前 SQL：

INSERT INTO `book` VALUES(1, 1, 1, 'These are the words in a sentence in a chapter in a book.');
INSERT INTO `book` VALUES(1, 1, 2, 'These are the words in the second sentence in a chapter in a book.');
INSERT INTO `book` VALUES(1, 1, 3, 'These are the words in the third sentence in a chapter in a book.');
...and so on.

当前的 VALUES 是 'book'、'chapter、'paragraph_number'、'paragraph'。

目标：

INSERT INTO `book` VALUES(1, 1, 1, 1,'These');
INSERT INTO `book` VALUES(1, 1, 1, 2,'are');
INSERT INTO `book` VALUES(1, 1, 1, 3,'the');
INSERT INTO `book` VALUES(1, 1, 1, 4,'words');

-new- VALUES 是 'book'、'chapter、'paragraph_number'、'paragraph'、'word_number'。

我已经有了书、章节和段落的编号。

例如：

INSERT INTO `book` VALUES(1, 5, 16, 'This is a sentence from book 1, chapter 5, paragraph 16.');

将转换为：

INSERT INTO `book` VALUES(1, 5, 16, 1,'This');
INSERT INTO `book` VALUES(1, 5, 16, 2,'is');
INSERT INTO `book` VALUES(1, 5, 16, 3,'a');
INSERT INTO `book` VALUES(1, 5, 16, 4,'sentence');
INSERT INTO `book` VALUES(1, 5, 16, 5,'from');
INSERT INTO `book` VALUES(1, 5, 16, 6,'book');
INSERT INTO `book` VALUES(1, 5, 16, 7,'1,');
INSERT INTO `book` VALUES(1, 5, 16, 8,'chapter');
INSERT INTO `book` VALUES(1, 5, 16, 9,'5,');
INSERT INTO `book` VALUES(1, 5, 16, 10,'paragraph');
INSERT INTO `book` VALUES(1, 5, 16, 11,'16.');

任何帮助将不胜感激......谢谢！

编辑：下面是有效的代码……基于 Akam 的回答……我更改了 SQL 语句。添加了 [SEP] 以将文本与允许我处理文本的其他数据分开。此外，添加了 $x 以增加字数。

SQL：

1, 1, 1,[SEP]These are the words in sentence 1 in chapter 1 in a book.
1, 1, 2,[SEP]These are the words in sentence 2 in chapter 1 in a book.

PHP：

$lines = file('my-book.sql');
$query = "INSERT INTO `book` VALUES \n";

foreach ($lines as $line)
{
    $part = preg_split("/\[SEP\]/", $line);
    $part[1] = preg_replace('~[\r\n]+~', '', $part[1]);
    $words = preg_split("/\s+/", $part[1]);

    $x = 1;
    foreach($words as $word)
    {
        $values[] = "(".$part[0]." ".$x.", '".$word."')";
        $x++;
    }

}

$new_lines = implode(",\n", $values);
$new_lines = $query.$new_lines.";";
echo $new_lines;

Answer 1

<?php
$text = 'This is a sentence from book 1, chapter 5, paragraph 16.';
$words = preg_split("/\s+/", $text);
$query = "INSERT INTO `book` VALUES \n";
foreach($words as $word){
 $values[] = "(1, 5, 16, 1,'$word')";
}
$finalquery = $query.implode(",\n", $values);
echo $finalquery.";";
?>

输出：

INSERT INTO `book` VALUES 
(1, 5, 16, 1,'This'),
(1, 5, 16, 1,'is'),
(1, 5, 16, 1,'a'),
(1, 5, 16, 1,'sentence'),
(1, 5, 16, 1,'from'),
(1, 5, 16, 1,'book'),
(1, 5, 16, 1,'1,'),
(1, 5, 16, 1,'chapter'),
(1, 5, 16, 1,'5,'),
(1, 5, 16, 1,'paragraph'),
(1, 5, 16, 1,'16.');
