按标题名称或索引从 CSV 中删除列

如何解决按标题名称或索引从 CSV 中删除列

我正在尝试使用 PHP 修改上传的 CSV 文件。更具体地说，我希望能够删除/删除列。

我有以下 CSV 文件（+10 万行）：

,news_headline,news_article,news_category
0,"50-year-old problem of biology solved by Artificial Intelligence"," DeepMind's AI system .....",technology   

我想要做的是保存 CSV 文件的新副本，但仅限于列：news_headline 和 news_category。

这是我当前的设置

use League\Csv\Reader;
use League\Csv\Writer;

//Read in current file.
$path = 'data.csv';
$reader = Reader::createFromPath($path);
$headers = ['news_headline','news_category'];
$records = $reader->getRecords($headers);

//Create a new file (override)
$writer = Writer::createFromPath($path);

//Insert new records
$writer->insertAll($records);

以上代码输出：

,news_headline
0,"50-year-old problem of biology solved by Artificial Intelligence"

我期待的地方：

news_headline,news_category
"50-year-old problem of biology solved by Artificial Intelligence",Technology
