Question

我使用pdftotext工具从pdf中提取了此文本

请在下面找到文本结构

stage    title1    title2  title3  title4
I        value1    value2  value3  
II                         value5  value6

stage    Other1      Other2     Other3     Other4
I        otherval1   otherval2  otherval3  otherval4

现在我要以这种方式使用适当的列和标题以CSV格式导出此文本，或者以这种方式构建数组

[
  "category" => "title1",
  "score"    => "value1",
],
[
  "category" => "title2",
  "score"    => "value2",
],
[
  "category" => "title3",
  "score"    => "value3"
],
// unable to to do this
[
  "category" => "title3",
  "score"    => "value5"
],
[
  "category" => "title4",
  "score"    => "value6",
],

.
.
// so on

现在问题是

I阶段和II阶段的列值是可选的，但以下任一项这些行的每一列将至少包含一个值
第二阶段行是可选的，可能存在或不存在
如果第二阶段行存在，则至少有一个列值存在行

我面临的问题是如何映射

将value5设置为title3
值6至titl4

这是我的解析器代码（PHP）

$rows = explode("\n", $pdfExtractedText);
$rows = array_values(array_filter($rows));

$categories = array_values(array_filter(explode(" ", $rows[7])));
$stage1Scores = array_values(array_filter(explode(" ", $rows[8])));
$stage2Scores = array_values(array_filter(explode(" ", $rows[9])));
var_dump($categories);
var_dump($stage1Scores);
var_dump($stage2Scores);

输出：

// categories
array:13 [
  0 => "stage"
  1 => "title1"
  2 => "title2"
  3 => "title3"
  4 => "title4"
]

//values - Index preserved so that I can map with categories
array:14 [
  0 => "I"
  1 => "value1"
  2 => "value2"
  3 => "value3"
  4 => "value4"
]

// index not preserved :(
array:2 [
  0 => "II"
  1 => "value5",
  2 => "value6"
]

然后尝试一下

$csv = "";

$csv .= implode("," , $categories) . PHP_EOL; 
$csv .= implode("," , $stage1scores) . PHP_EOL;
$csv .= implode("," , $stage2scores) . PHP_EOL;

然后将其写入文件。

如何将该文本转换为所需的数组格式并以csv格式导出？
