Can PHP code be evaluated within PHP echoes?

Utilizing PHP within PHP Echoes

Problem:

In scenarios with frequent usage of PHP snippets embedded in HTML, can PHP be utilized within PHP echoes? For instance:

<?php 
    echo "<?php the_author_meta('description'); ?>";
?>
Copy after login

Answer:

No, PHP cannot echo PHP code to be evaluated further due to PHP's single-pass interpretation. The code provided will output the text "" instead of interpreting it.

PHP Entry and Exit:

However, it is possible to switch between PHP and HTML interpretation freely:

<?php
echo "Interpreted by PHP.";
?>
I am not interpreted by PHP.
<?php
echo "Interpreted again by PHP.";
?>
Copy after login
