What are the best practices for posting code in forums to ensure clarity and readability?

When posting code in forums, it is important to ensure clarity and readability for other users. To achieve this, it is recommended to provide a brief explanation of the issue or how to solve it before sharing the code snippet. This helps users understand the context and purpose of the code. Additionally, formatting the code properly with proper indentation, comments, and line breaks can greatly improve readability. Finally, using code blocks or syntax highlighting features available in most forums can make the code stand out and easier to read.

// Example code snippet
$variable = "Hello, World!";
echo $variable;
