使用PHP按某些关键字解析PDF文件并将其拆分为多个PDF文件

我希望能够使用 PHP 和 symfony 4 框架使用某些关键字解析 PDF 文件，并根据搜索的关键字将其拆分为多个 PDF 文件。

我做了一些研究，发现很多使用 PHP 解析 PDF 文件的方法，但解析和分割 PDF 文件的方法很少。

我可以访问哪些网站？我可以使用的库吗？

这是我用来从 pdf 文件中提取整个文本的代码。但我的目的是从pdf中提取特定段落，例如我想提取从“hello”一词开始到“world”一词的段落。

public function extract(): Response {
$parser = new \Smalot\PdfParser\Parser();
        $CV = $parser->parseFile('C:\Users\lenovo\Desktop\papiers\CV\CVmolkahchaichi.pdf');

        // Retrieve all pages from the pdf file.
        $details = $CV->getDetails();
        $pages  = $CV->getPages();

        // Loop over each page to extract text.
        foreach ($pages as $page) {
            echo $page->getText();
            foreach ($details as $property => $value) {
                if (is_array($value)) {
                    $value = implode(', ', $value);
                }
                echo $property . ' => ' . $value . "<br/>";
            }
            return new Response();
}

I'd like to be able to parse a PDF file using PHP and symfony 4 framework using certain keywords and split it into multiple PDF files at the keywords searched for.

I did some research and I found a lot of ways to parse PDF files using PHP but very few to parse and split the PDF file.

any web-sites I could go to? libraries I could use?

this is the code I used to extract the whole text from a pdf file. But my purpose is to extract specific paragraphes from the pdf, for example I want to extract the paragraph that starts from the word 'hello' to the word 'world'.

public function extract(): Response {
$parser = new \Smalot\PdfParser\Parser();
        $CV = $parser->parseFile('C:\Users\lenovo\Desktop\papiers\CV\CVmolkahchaichi.pdf');

        // Retrieve all pages from the pdf file.
        $details = $CV->getDetails();
        $pages  = $CV->getPages();

        // Loop over each page to extract text.
        foreach ($pages as $page) {
            echo $page->getText();
            foreach ($details as $property => $value) {
                if (is_array($value)) {
                    $value = implode(', ', $value);
                }
                echo $property . ' => ' . $value . "<br/>";
            }
            return new Response();
}
