How Should I Indent Mixed PHP/HTML Code for Optimal Readability?

Proper Indentation for Mixed PHP/HTML Code

When combining PHP and HTML code, the appropriate indentation style depends on the context. Both approaches presented in the question have their own merits:

Indenting for Outputted HTML Clarity

Indenting the PHP code solely for presenting clean outputted HTML ensures that the generated HTML is properly formatted and readable. This approach eliminates redundant indentation for the PHP code itself, making it easier to visually parse the HTML output.

Indenting for PHP/HTML Readability

On the other hand, indenting both PHP and HTML based on their own syntax enhances the readability of the mixed code. By indenting the PHP code indentation separately from the HTML, it becomes more straightforward to comprehend the logic and flow of the program.

Recommendations

Ultimately, the choice of indentation style for mixed PHP/HTML code is subjective. However, a recommended approach is to indent both the PHP and HTML code independently, so that:

• The PHP code adheres to standard PHP indentation practices for readability.
• The HTML code adheres to standard HTML indentation practices for output clarity.

This approach combines the benefits of both methods, providing both intuitive PHP logic interpretation and well-formatted HTML output.
