For example, the following code will create a link that will call a PHP script and close the current page when clicked:

Close Page

2. Create a PHP script that will run when the user clicks a link and close the current page. Here is a simple PHP script example:

echo '<script>window.close();</script>';
?>

When the user clicks the close page link, this PHP script will add a Javascript code to the current page, which will close the current window.

3. Save the PHP script as close.php and deploy it on the website. Make sure to set the href attribute of the HTML page link or button to close.php.

Now when the user clicks the close page link, the PHP script will run and close the current window. This method can close the WeChat browser page through PHP and avoid the security risks caused by using JavaScript's window.close() method.
