如何在 PHP 中將 HTML 轉換為純文字以進行有效的電子郵件推廣？

Converting HTML to Plain Text for Effective Email Outreach in PHP

To enhance user engagement, many websites utilize text editors like TinyMCE that enable basic text formatting. However, when conveying this formatted content via email, it's essential to convert it to plain text for optimal readability. While the html2text class has been commonly employed for this purpose, it lacks UTF-8 support and other limitations.

Recommended Third-Party Classes for HTML to Plain Text Conversion

One highly recommended class for HTML to plain text conversion in PHP is html2text. Licensed under the Eclipse Public License, this class utilizes PHP's DOM methods to parse HTML and extract plain text content.

Usage of html2text

To use the html2text class, follow these steps:

// Composer package usage
$text = Html2Text\Html2Text::convert($html);

// html2text.php usage
require('html2text.php');
$text = convert_html_to_text($html);

Additional Conversion Script Alternatives

While html2text is a viable option, it's important to note its incompleteness. However, it's open source, welcoming contributions from the community.

Compatibility Considerations

When considering other conversion scripts, it's crucial to assess their compatibility with open source licenses. For instance, html2text (GPL) is not EPL-compatible, while lkessler's script has attribution restrictions that conflict with open source usage.
