PHP ("PHP: Hypertext Preprocessor", hypertext preprocessing (abbreviation for HTML) is a widely used open source multi-purpose scripting language that can be embedded in HTML and is especially suitable for web development.
Let me give you an example and you will understand.
<html> <head> <title>Example</title> </head> <body> <a hre="#">我是a链接</a> <?php echo "Hi, I'm a PHP script!".'<a hre="#">我是链接</a>'; ?> </body> </html>
In HTML documents it is the closing tag of the A tag, and it can also be used in PHP scripts.
</a>是html标签 是链接的结束符 <a href="" >链接 </a>
