To display a message box in PHP, you can achieve this by using the alert function in JavaScript. Here is a simple example code:<\/p>\n
<?php<\/span>\r\nif<\/span> ($_SERVER<\/span>['REQUEST_METHOD'<\/span>] == 'POST'<\/span>) {\r\n \/\/ \u5904\u7406\u8868\u5355\u63d0\u4ea4<\/span>\r\n \/\/ ...<\/span>\r\n\r\n \/\/ \u5f39\u51fa\u63d0\u793a\u6846<\/span>\r\n echo<\/span> '<script>alert(\"\u63d0\u4ea4\u6210\u529f\uff01\");<\/script>'<\/span>;\r\n}\r\n?><\/span>\r\n\r\n<!DOCTYPE html>\r\n<html>\r\n<head>\r\n <title>\u5f39\u51fa\u63d0\u793a\u6846<\/title>\r\n<\/head>\r\n<body>\r\n <form method=\"POST\"<\/span>>\r\n <!-- \u8868\u5355\u5185\u5bb9 -->\r\n <input type=\"submit\"<\/span> value=\"\u63d0\u4ea4\"<\/span>>\r\n <\/form>\r\n<\/body>\r\n<\/html>\r\n<\/code><\/pre>\nIn the example above, PHP code is executed to handle form submission when the user clicks the submit button, and then JavaScript code is echoed to display a popup message. The message in the popup can be modified as needed.<\/p>\n","protected":false},"excerpt":{"rendered":"
