Need Help with PHP Error: Undefined Variable while Developing Laptop E-commerce Site

I hope you're all having a great day! I'm currently working on an exciting project – building an e-commerce website that sells laptops. However, I've run into a bit of a roadblock while coding.

Here's the scenario: I'm working on a crucial part of the website where I want to display the laptop prices dynamically. To achieve this, I've written the following PHP code snippet:

<?php
// Extracted laptop price from the database
$laptopPrice = 1299.99;

// Trying to display the price
echo "The laptop is priced at: $" . $laptopPrice;
?>

The problem is that when I try to execute this code, I get the following error message:

Notice: Undefined variable: laptopPrice in index.php on line 6

I've been scratching my head trying to figure out what's going wrong here. I've double-checked my code, and it seems like the $laptopPrice variable should be defined properly. Could there be something I'm missing?

Has anyone encountered a similar issue or can spot what I might be doing wrong? I'm eager to learn and fix this

The error message you're encountering, "Notice: Undefined variable: laptopPrice in index.php on line 6," typically occurs when you try to use a variable that hasn't been defined or initialized before you attempt to use it. In your PHP code snippet, it appears that you have defined the $laptopPrice variable, but there are a few possibilities for why you might still be seeing this error:

Variable Scope Issue: Ensure that your PHP code snippet is within the PHP context and not mixed with HTML code. If it's mixed with HTML, PHP may not recognize the variable correctly.
*Correct Usage (PHP File):
*

<?php
// Extracted laptop price from the database
$laptopPrice = 1299.99;

// Trying to display the price
echo "The laptop is priced at: $" . $laptopPrice;
?>
File Inclusion/Execution Order: Make sure that the PHP code you provided is executed after the variable $laptopPrice has been defined. If you're including this PHP code from another file, ensure that the inclusion order is correct.

Syntax Errors or Typos: Check for any syntax errors or typos in your code that might prevent the variable from being recognized correctly. In your provided code, there don't seem to be any syntax errors.

File Permissions: Ensure that the file you're working with has the correct file permissions. File permission issues can sometimes lead to unexpected behavior in PHP.

If none of the above suggestions resolve the issue, consider providing more context or additional code surrounding the snippet you've shared, as there may be an issue outside of the code you've posted that is causing the problem. Additionally, check for any potential naming conflicts with variables elsewhere in your code that might be affecting the scope of $laptopPrice.
