Thinking about ways to close the page in PHP5

When developing a web application, you may need to close the page in some situations. For example, when a user successfully submits a form or performs some action, the page may need to be closed. In this case, you need to send a message to the user telling them that the operation completed successfully and close the current page. For many web developers, closing a page is a very important and common task. In this article, we will introduce how to implement the method of closing the page under the ThinkPHP5 framework.

1. Use JavaScript to close the page

The most common way to close the page is to use JavaScript. JavaScript is a client-side scripting language that executes in the user's browser, helping you create dynamic web applications. One of its advantages is that the window or browser can be closed on the client side. Here is a JavaScript function that can help you close the page in ThinkPHP5:

function close_window() {
   if (confirm("是否关闭窗口?")) {
      close();
   }
}
Copy after login

In View, you can embed this function into your HTML code like this:

<a href="javascript:close_window()">关闭页面</a>
Copy after login

When the user clicks the "Close Page" link, a confirmation box will appear asking the user if they want to close the window. If the user clicks the "Confirm" button, the page will close.

2. Use PHP code to close the page

In addition to JavaScript, you can also use PHP code to close the page. Under the ThinkPHP5 framework, you can use PHP's Header function to achieve this purpose. The Header function is used to send HTTP headers to the client browser. You can use this function to send a command to the client browser that tells the browser to close the window or browser. The following is an example of PHP code that uses the Header function to close the page:

if (isset($_GET['close'])) {
   header('Location: about:blank');
   die();
}
Copy after login

In the above code, we first check whether the "close" parameter exists in the $_GET array. If it exists, use the Header function to set the location to "about:blank" (a blank page). Then use the die() function to stop the execution of the script. This will cause the client browser to load a web page pointing to "about:blank", thus closing the browser or window.

You can call this PHP function in Controller or put it in View. For example, in View, you can create a link that points to the above PHP code:

<a href="/close-page?close=1">关闭页面</a>
Copy after login

When the user clicks the link, a GET request will be sent containing the "close" parameter. While this request is being processed, the above PHP code will close the page.

3. Use HTML code to close the page

In addition to using JavaScript and PHP, you can also use HTML code to close the page. The tag in HTML has a target attribute that sets the target of the page to _blank. This will open a new window with a blank page. Since the new window is blank, you can assume you just closed the original page. Here is a sample HTML code to help you close a page using HTML in ThinkPHP5:

In the above code, we have created a link with its target set to _blank and the location set to "about:blank". When the user clicks the link, a new window opens with a blank page. This will close the original page or window.

Summary

In this article, we introduced three different ways to close the page in ThinkPHP5: JavaScript, PHP and HTML code. JavaScript is the most common solution, but this method won't work if JavaScript is disabled. Since PHP and HTML code are executed in the background, they always work properly, even if JavaScript is disabled. No matter which method you choose, you should carefully consider the needs of your web application and choose the solution that works best for you.
