Application of non-PHP tags in web development

In web development, PHP is a very commonly used server-side scripting language, which can be used in conjunction with HTML , dynamically generate web content. In addition to using PHP tags in PHP files, you can also use non-PHP tags to achieve more flexible development and design. This article will introduce the application of non-PHP tags in web development, including specific code examples.

1. HTML comments

In the process of web development, we often need to add comments to explain the code or hide some temporarily unnecessary parts. HTML comments are tags that are not displayed in the browser but work on the code, helping us better maintain and manage the code.

<!-- 这是一个 HTML 注释 -->

</script>
