How HTML calls PHP

HTML itself cannot handle dynamic requests. To accomplish this, JavaScript is generally used. When generating a static web page, you can generate a corresponding JavaScript file reference for the HTML page based on the database ID. For example, if the page is 123.html, then generate a

<script type="text/javascript" src="click.php?id=123"></script>

on this page, and then on the click.php page, just process and operate the database according to the syntax of PHP.

静态页面中是不能直接调用php文件,但是有可以使用js调用方式来调用php文件,还可以使用ajax 调用php文件。
举一个简单的例子来说明:在页面a.html中使用如下代码,可以将action=test的参数传递到b.php。
Javascript代码如下:
<script type="text/javascript" src="b.php?action=test"></script> 
在b.php中有这样一段PHP代码:
<?php

	$action=$_GET['action'];     
	echo "document.write('".$action."');n";    
?>
