如何使用php代码点火器读取docx文件数学方程式 [英] how to read docx file math equations using php code-igniter

问题描述

我正在尝试从php读取docx文件，因为我读取成功，但是我没有在word文档中得到一些方程式，因为我是php的新手，所以我不知道如何阅读，请提出一些建议，功能我尝试阅读的文档是

I am trying to read a docx file from php, as i read successfully but i didnt get some equation in the word document, as i am newbie in php i didnt know how to read that please suggest some ideas, the function i have tried to read the document is

function index()
{
    $document = 'file_path';
    $text_output = $this->read_docx($document);
    echo nl2br($text_output);

}
private function read_docx($filename) 
{
    var_dump($filename);
    $striped_content = '';
    $content = '';

    $zip = zip_open($filename);

    if (!$zip || is_numeric($zip))
        return false;

    while ($zip_entry = zip_read($zip)) {

        if (zip_entry_open($zip, $zip_entry) == FALSE)
            continue;

        if (zip_entry_name($zip_entry) != "word/document.xml")
            continue;

        $content .= zip_entry_read($zip_entry, zip_entry_filesize($zip_entry));

        zip_entry_close($zip_entry);
    }// end while

    zip_close($zip);

    $content = str_replace('</w:r></w:p></w:tc><w:tc>', " ", $content);
    $content = str_replace('</w:r></w:p>', "\r\n", $content);
    $striped_content = strip_tags($content);

    return $striped_content;
}

这是docx文件中的示例数学方程式，我正尝试读取并呈现到html页面.谢谢

This is the sample math equation in the docx file which i am trying to read and render to html page. thanks

打印$ final_arr，您将获得文档中的所有文本和图像.

print the $final_arr you will get the all text and images in the document.
