Why Your PHP While Loop with HTML Code is Not Executing: A Common Parse Error Explained

When working with PHP to perform CRUD (Create, Read, Update, Delete) operations, it can be frustrating to encounter errors, especially those related to syntax. One common issue developers face is the Parse error: syntax error, unexpected '?>' while trying to loop through results from a database query intertwined with HTML code. If you've stumbled upon this error, you're not alone – let's explore why this happens and how to fix it.

The Problem: Unclosed While Loop

In your PHP code, you aim to fetch data from a database and display it in an HTML table. However, the code is resulting in a Parse Error. The primary issue lies in the syntax used in your while loop. Here’s a look at the problematic section of code:

This line has a missing closing parenthesis, which PHP interprets as a syntax error. This is a common mistake that can easily throw off your program execution.

The Solution: Correcting the Syntax

To resolve this error, you simply need to ensure your while loop is properly closed with parentheses. The corrected code should look like this:

The only change made here is the addition of the closing parenthesis ) after $res, ensuring the loop is syntactically complete.

Updated Complete Code Example

Let’s take a closer look at the complete and corrected structure. Make sure that your code resembles this format:

Key Takeaways

Always ensure that your parentheses are properly matched in your code.

Take extra care in PHP scripts that combine both PHP and HTML, as small syntax errors can lead to execution issues.

Utilize code editors that provide syntax highlighting to catch errors early.

Conclusion

Encountering errors like the Parse Error can be a frustrating part of coding, but understanding the structure and syntax of your code can go a long way in preventing them. Always double-check your while loops and their corresponding syntax, and you'll find that these issues can be resolved quickly. Happy coding!
