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> </p>";
} else {
echo "<h2 id=\"" . $row['tag'] . "\">" .
$row['title'] . "</h2>" .
wordwrap($row['content'],$width_wrap,"\n",0) .
"<p> </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']
