PHP: Execute php code inside "php echo" -

i've got php code created echo:

<?php    code...   $line = "hello world";   echo "<li>php if (!empty($line)) { echo $line; }</li>"; ?>

unfortunately <li> not show hello world. can see here: http://codepad.org/qfcsindy

your syntax wrong. check this

<?php   code...  ?> <li><?php echo 'hello world'; ?>  <?php ?>

or just

<?php   code...  echo "<li>hello world</li>"; ?>
