Alert in PHP: Displaying An Alert Message Box in PHP

PHP was started, believe it or not, as an open source project that soon gained considerable popularity as developers and software professionals began discovering its immense use. It was in 1994, that its creator, Rasmus Lerdorf released the first edition of PHP — one of today’s most popular programming languages.

Basics to Advanced — Learn It All!

PHP is in essence a server-side, HTML-enabled scripting language. It is most popularly and effectively used to handle databases, dynamic content, session monitoring, and to create full-fledged e-commerce websites.

MySQL, PostgreSQL, Oracle, Sybase, Informix, and Microsoft SQL Server are only a few of the databases it supports.

What is an Alert in PHP?

A warning message is shown to the user using an alert in PHP. While PHP does not have the ability to view a warning message box, you can use the JavaScript code embedded within the PHP code to do so. You can use PHP to view a JavaScript warning message box in this manner.

A warning box or alert in PHP is a pop-up window on your computer that displays a message or information that needs the user’s attention. Browsers support warning boxes, which are JavaScript dialogue boxes.

PHP is a server-side language, so it does not support pop-up warning messages. The client’s browser displays a warning. You need to make JavaScript code in PHP and send it to the browser to send a warning message through PHP. The client-side language is JavaScript.

Alert Message Using PHP

1. Pop-Up Alert Message Taking Value From PHP Variable and JavaScript
2. Pop-Up Alert Message Using PHP Function JavaScript
3. Pop-Up Alert Message Using an Array or an Object

PHP does not have any built-in function for popping alert messages, but we can pop alert messages in PHP using JavaScript. The alert messages are shown in pop-up boxes in the browser, usually used for popping warning messages.

JavaScript helps PHP to show dynamic alert messages in the pop-up box. This tutorial demonstrates how we can use PHP and JavaScript to pop-up alert messages.

Pop-Up Alert Message Taking Value From PHP Variable and JavaScript

To pop-up alert messages in PHP is to put the variable into the javascript alert() method.

php // Sending Alert message using PHP variable.  $alert = "This is DEMO WARNING"; echo ""; ?> 

The above code will pop up an alert box in the browser showing the value of the $alert variable.

Pop-Up Alert Message Using PHP Function JavaScript

We can create a PHP function for popping the alert messages.

php // Sending alert messages using PHP function  $message1= "This is the PHP function alert 1"; $message2= "This is the PHP function alert 2"; function alert($message)   echo ""; > alert($message1); alert($message2); ?> 

This code will pop up a second alert message once you press the “ok” button on the first alert message.
