How to convert a word document to html document in php

With the advent of the digital era, more and more companies, institutions and individuals need to digitize documents. As a very important document processing software, Microsoft Word's file format doc is becoming more and more widely used. However, if you convert a doc file to other document formats, obtain its content and process it, you need to use certain tools and technologies. This article will explore how to use PHP language to convert a Word document into an HTML document.

1. Word documents and HTML documents

Before we start discussing how to convert Word documents to HTML documents, we need to understand the difference between Word documents and HTML documents.

Word document is a binary format file, that is to say, its content cannot be read or parsed directly. It requires specific software (such as Microsoft Word or OpenOffice Writer, etc.) to open and view the content. content.

HTML document is a text-based markup language, in which the content is described in a certain format of markup language and can be displayed directly through the browser. The content of HTML documents can be optimized by search engines and other web crawlers to facilitate retrieval and processing of the content.

2. PHP processing of Word documents

Since Word documents are files in binary format, they need to be processed with the help of specific software, and PHP is not good at processing binary files. Therefore, before using PHP to process Word documents, we need to use some tools to assist us in processing.

Here, we use the PHPWord PHP library to parse the Word document and extract its content. PHPWord supports the import of documents in multiple formats (including Word, OpenOffice, RTF, HTML, and plain text, etc.), and also supports the export of documents in multiple formats (including Word, PDF, HTML, and plain text, etc.).

In PHPWord, we can use the following code to import Word documents:

// 引入autoload
require_once 'vendor/autoload.php';
 
// 实例化 PHPWord
$phpWord = \PhpOffice\PhpWord\IOFactory::load('document.docx');
 
// 获取文档内容
$section = $phpWord->getSection(0);
$text = $section->getText();

In the above code, we first require_once import the autoload.php file of the PHPWord library, and then use IOFactory's load( ) method to read a Word document and return a PHPWord instance. Finally, the getSection() method and getText() method are used to obtain the content of the first Section in the Word document.

3. Convert Word document to HTML document

After getting the content of the Word document, we can start converting it to HTML document. Here, we use the HTML Writer implementation provided by PHPWord to convert text into HTML format.

The following is the complete code to convert a Word document to an HTML document:

// 引入autoload
require_once 'vendor/autoload.php';
 
// 实例化 PHPWord
$phpWord = \PhpOffice\PhpWord\IOFactory::load('document.docx');
 
// 获取文档内容
$section = $phpWord->getSection(0);
$text = $section->getText();
 
// 转换为HTML
$htmlWriter = \PhpOffice\PhpWord\IOFactory::createWriter($phpWord , 'HTML');
$html = $htmlWriter->save('php://memory');
 
// 输出HTML结果
echo $html;

In the above code, we use the createWriter() method of IOFactory to convert the PHPWord instance into an HTMLWriter instance, and use The save() method saves it to PHP's memory stream. Finally, we can output the HTML content to the browser through the echo command.

4. Conclusion

In the current digital era, document processing has become one of the skills that must be mastered in various industries. The method of converting Word documents into HTML documents introduced in this article is also an important step in digitizing Word documents. By using PHPWord, a PHP library, we can easily convert Word documents into HTML documents. Hope this article will be helpful to you.
