In the OnClick event of the button, insert JavaScript code that points to the PHP script which you want to run when the button is clicked.
在按钮的 OnClick 事件中，插入指向单击按钮时要运行的 PHP 脚本的 JavaScript 代码。
<input type="button" value="Say Hi!" onclick="location='test.php'" />

Ahmad Farid, how say Geoffrey Van Wyk, you can use the event "onclick" of an input element (button, for example).
Ahmad Farid，Geoffrey Van Wyk 怎么说，您可以使用输入元素（例如按钮）的“onclick”事件。
Maybe AJAX is your solution (not reload all page). A simple example of 'click' and run a script (maybe CGI, or PHP) it's here: http://www.degraeve.com/reference/simple-ajax-example.php
也许 AJAX 是您的解决方案（不是重新加载所有页面）。“单击”并运行脚本（可能是 CGI 或 PHP）的简单示例位于此处：http: //www.degraeve.com/reference/simple-ajax-example.php
Easy & useful :)

PHP doesn't work like .Net. So what you are talking about it actually not directly possible.
PHP 不像 .Net 那样工作。所以你所说的实际上并不是直接可能的。
What you will need to do is create the raw markup for your form. At minimum a form tag and your button. Set the form's action to a php script on your server, such as "button_action.php" and have it accept, via GET or POST, whatever data you wanted to send. (or if you are just talking about enacting some action, you don't need to check anything)
您需要做的是为表单创建原始标记。至少有一个表单标签和你的按钮。将表单的操作设置为您服务器上的 php 脚本，例如“button_action.php”，并让它通过 GET 或 POST 接受您想要发送的任何数据。（或者，如果您只是在谈论制定某些行动，则无需检查任何内容）
Again, this isn't .Net, so there is no postback, and you will not come back to the page. If you want to do that, you will have to redirect back from your other script.
同样，这不是 .Net，因此没有回发，您将不会返回该页面。如果你想这样做，你将不得不从你的其他脚本重定向回来。
