What are the best practices for outputting HTML content in PHP to minimize unnecessary work for the parser?

When outputting HTML content in PHP, it is important to minimize unnecessary work for the parser by using single quotes for strings that do not require variable interpolation. This prevents PHP from parsing the string for variables, saving processing time. Additionally, using concatenation instead of interpolation for variable insertion can also improve performance. 

// Example of minimizing unnecessary work for the parser when outputting HTML content in PHP
$name = "John";

// Bad practice - unnecessary work for the parser
echo "<p>Hello, $name!</p>";

// Good practice - using single quotes for static strings
echo '<p>Hello, ' . $name . '!</p>';
