2. Use PHP to convert Word to HTML

In addition to using PHPWord, we can also use PHP's own ZipArchive class to process Word documents and convert them to HTML.

Decompress Word files

First, you need to decompress the Word document into XML files and other resource files. Here, use the ZipArchive class for decompression. Code example:

$wordFile = 'example.docx';

$zip = new ZipArchive;
if ($zip->open($wordFile) === true) {
    $tmpdir = '/tmp/myproject/' . uniqid();
    mkdir($tmpdir);

    $i = 0;
    while (($entry = $zip->getNameIndex($i++)) !== false) {
        $entryFilename = $tmpdir . '/' . $entry;
        if (substr($entry, -1) == '/') {
            mkdir($entryFilename);
        } else {
            file_put_contents($entryFilename, $zip->getFromIndex($i - 1));
        }
    }

    $zip->close();
}

Copy after login

Parsing XML files

After obtaining the decompressed Word document, you need to parse the XML file and generate HTML code.

Code example:

$xmlFile = $tmpdir . '/word/document.xml';
if (file_exists($xmlFile)) {
    $xml = simplexml_load_file($xmlFile);
    echo '<html><body>';

    foreach ($xml->body->p as $paragraph) {
        echo '<p>';
        foreach ($paragraph->r as $text) {
            if (isset($text->b)) {
                echo '<b>' . htmlspecialchars((string)$text->t) . '</b>';
            } else {
                echo htmlspecialchars((string)$text->t);
            }
        }
        echo '</p>';
    }

    echo '</body></html>';
}
