How to Display Alert Message Box in PHP?

Alert boxes are used for displaying a warning message to the user. As you know that PHP does not have the feature to popup an alert message box, but you can use the javascript code within the PHP code to display an alert message box. In this way, you can display an alert message box of Javascript in PHP.

JavaScript has three types of pop-up boxes, which are the following:

In this article, you will learn about the alert box, confirmation box, and prompt box with examples.

1. Display alert box in PHP

An alert box is nothing but a pop-up window box on your screen with some message or information which requires user attention.

An alert box is a JavaScript dialog box that is supported by browsers.

PHP is a server-side language and does not support pop-up alert messages. The browser of the client renders an alert.

To pop an alert message via PHP, we need to render JavaScript code in PHP and send it to the browser. JavaScript is a client-side language.

alert(«Type your message here»);

Example: Using the JavaScript alert box

    '; echo ' alert("JavaScript Alert Box by PHP")'; //not showing an alert box. echo ''; ?> 

Example: Using the PHP function

    alert('$msg');"; > ?> 

2. Display confirm box in PHP

A confirm box mostly used to take user’s approval to verify or accept a value.

confirm(«Type your message here»);

Example: Using the Javascript confirmation pop-up box

   '; echo ' function openulr(newurl) '; echo '>'; echo ''; > ?> Open new URL  

     Open new URL  

3. Display prompt box in PHP

A prompt box is mostly used, when you want the user input, the user needs to fill data into the given field displaying in the pop-up box and has to click either ok or cancel to proceed further.

prompt(«Type your message here»);

Example: Using the Javascript prompt pop-up box

    '; echo 'var inputname = prompt("Please enter your name", "");'; echo 'alert(inputname);'; echo ''; > ?>

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.

Pop-Up Alert Message Using an Array or an Object

We can also use an array or an object instead of a variable to print in an alert box.

php $alert = ["this", "is", "a", "demo", "warning"]; ?>  var JavaScriptAlert = ; alert(JavaScriptAlert); // Your PHP alert!  

json_encode() is a built-in PHP function that converts the array or an object to a simple JSON value.

The alert() function is compatible with every major browser.
