What are the best practices for adding newlines in PHP output to improve code readability?

Adding newlines in PHP output can greatly improve code readability by making the output easier to scan and understand. One common practice is to use the "\n" character to insert a newline in the output string. This can be especially useful when outputting HTML code or long strings of text. Additionally, using proper indentation and spacing can further enhance the readability of the code.
