What are the best practices for using code tags and formatting when posting PHP code on a forum thread for assistance?

When posting PHP code on a forum thread for assistance, it's important to use code tags to ensure that the code is properly formatted and easy to read for others. Start by giving a brief explanation of the issue or how to solve it in 3 to 5 sentences. Then, on a new line, provide the complete PHP code snippet that implements the fix within the code tags. This will help others understand the problem and provide more accurate assistance. Remember to also include any relevant context or details that may be helpful for others to understand the code snippet.
