The method of popping up a dialog box in PHP is as follows. Generally, a dialog box prompt needs to pop up after submitting information, and then the dialog box can be automatically closed. There are following centralized methods for popping up a dialog box. In fact, they all use the alert() method in JavaScript. Closing the current page after the prompt ends can also be achieved using javascript's Window.self.close().

The exact statement is: echo " <script> window.self.close(); </script> ";

1.php pop-up dialog box
//pop-up dialog box
echo " ";
?>

//Close the current page

echo " <script> window.self.close (); </script> ";
or
print "";
?>
2. If you need php to pop up a dialog box and return to the original page, you can write like this
echo "";
exit;
?>
or
print "";
exit;
?>
3. If necessary After php pops up the dialog box, replace the original page with the new page (replace the current history record). The original page can be written like this
echo "";
exit;
?>
or
print "";
exit;
?>
