I had a problem when I tried to execute the following: <?php while ($row = mysql_fetch_assoc($result)) { if($row['eval'] == "1") { echo "<h2 id=\"" . $row['tag'] . "\">" . $row['title'] . "</h2>" . wordwrap(eval("?>" . $row['content'] . "<?php "),$width_wrap,"\n",0) . "<p>&nbsp;</p>"; } else { echo "<h2 id=\"" . $row['tag'] . "\">" . $row['title'] . "</h2>" . wordwrap($row['content'],$width_wrap,"\n",0) . "<p>&nbsp;</p>"; }; }; ?> As the values came out it seemed like this: eval = 0 >> outputs a correct $row['content'] eval = 1 >> value of eval("?>" . $row['content'] . "<?php ") appended to the previous $row['content'] (yes: in between the </h2> and <p> tag) and $row['content'] was empty in the current iteration of the while statement. eval = 1 >> the same thing happened, the value was appended to the previous $row['content'] which was empty at that time and the current iteration was empty eval = 0 >> outputs a correct $row['content'] ---- Manual Page -- http://www.php.net/manual/en/function.eval.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+54871 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+54871&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+54871&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+54871&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+54871&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+54871&report=yes&reason=non-english Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+54871&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+54871&report=yes Search -- http://master.php.net/manage/user-notes.php
