PHP: trying to put href HTML attribute into a `echo`

I can't seem to get a URL into

. I want to make a link to open Google Maps:

enter image description here

I can't figure out what's wrong with my code:

$query = mysql_query("SELECT * FROM cev")or die(mysql_error());
while($row = mysql_fetch_array($query))
$name = $row['sitecode'];
$lat = $row['latitude'];
$lon = $row['longitude'];
$type = $row['sitetype'];
$city = $row['city'];
$id = $row['id'];

echo("addMarker($lat, $lon,'<b>$name</b><a href="editcev.php?id=' . $row['id'] . '">View</a><br><br/>$type<br/>$city');\n");

Answer Source

You have to fix the quotes:

 echo "addMarker($lat, $lon,'<b>$name</b><a href=\"editcev.php?id={$row['id']}\">View</a><br><br/>$type<br/>$city');\n";

Alternative ways

Here document

echo <<<EOS
addMarker($lat, $lon, '<b>$name</b><a href="editcev.php?id={$row['id']}">View</a><br><br/>$type<br/>$city');



echo "addMarker($lat, $lon, '<b>$name</b>" .
  "<a href=\"editcev.php?id={$row['id']}\">View</a>" .

Using addshashes

The addMarker looks like a JavaScript function. You might pre-process the HTML string by means of addslashes:

$html = <<<EOS
<b>$name</b><a href="editcev.php?id={$row['id']}">View</a><br><br/>$type<br/>$city
$html = addslashes($html);

echo "addMarker($lat, $lon, '$html');\n";


I recommend using an editor with support of syntax highlighting.

Read about PHP strings. Especially the matter of escaping.

Finally, I wouldn't recommend writing any HTML/JavaScript within a PHP code. Use template engines such as Smarty or Twig instead.
