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
If you believe you need to output PHP code that undergoes further evaluation, there are more appropriate approaches. Provide a practical example of your intended outcome, and the Stack Overflow community will gladly assist.
