Can You Nest PHP Inside `echo` Statements?

Can PHP Embellish Itself Through Echoes?

In situations where PHP fragments frequently appear within HTML, as seen in WordPress, is it possible to nest PHP inside echo statements? For instance:

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

While such nesting may seem unwarranted, is it feasible? Furthermore, how do you halt and resume PHP when interweaving it with HTML, particularly when the latter contains PHP snippets?

Echoes and PHP's Single-Pass Interpretation

Alas, PHP cannot evaluate code that is echoed because it interprets code in a single pass. If you attempt something like this:

<?php echo '<?php echo "hello"; ?>'; ?>

PHP will merely output the literal text "".

Jumping In and Out of PHP

You can, however, seamlessly transition between PHP and HTML:

<?php
echo "I'm processed by PHP.";
?>
I'm left alone by PHP.
<?php
echo "I'm back in the PHP sandbox.";
?>

Finding Alternatives
