Echoing <a> tag with PHP variables involved

I'm looking to echo an hyperlink in a PHP file. The target and text are variables. And no, I can't just make a html file and then echo out the variables. It has to be done with echoing out the statement. I'm having problems with the " " around the target. The first " is okay, but the second is causing problems. Here is 开发者_StackOverflow社区my code.

while($row = mysql_fetch_assoc($result)){
if (!empty($row[adder])) {
echo "<a href=\"/".$row[adder].\"">".$row[adder]."</a>";
}

The problem is the \" after $row["adder'].

any idea why the error:

Warning: Unexpected character in input: '\' (ASCII=92) state=1 in /home//public_html/folder/index.php on line 116

is coming up??

I'm sure its just a missing " or something..

Thanks, Niall

The backslash needs to be shifted one position to the right. You can see where it goes wrong by the coloring.

Change this line:

echo "<a href=\"/".$row[adder].\"">".$row[adder]."</a>";

To:

echo "<a href=\"/".$row[adder]."\">".$row[adder]."</a>";

Your backslash is one " too soon:

echo "<a href=\"/".$row[adder]."\">".$row[adder]."</a>";

Try

echo '<a href="'.$row[adder].'">'.$row[adder].'</a>';
