php not recursively embeddable. following

<?php  echo "<?php echo 'hi mom!' ?>"; 

will output literal characters <, ?, p etc... "internal" echo not executed, because it's not php code - it's characters in string.

note if you're outputting text html context (e.g. web browser), <?php tag mis-interpreted invalid/illegal html tag, , skipped browser. in case, have do

echo "<?php echo 'hi mom!' ?>" 

remember - you're not outputting php code, you're outputting text, , if it's going web page, text has valid html.
