Using json_encode for URL using PHP and MYSQL

Question

I need to retrieve URL's which are coming from a PHP file which include mysql variables. Unfortunately they are not being returned correctly.

Below is the html file I am linking to:

<!doctype html>
<html>
<head>
  <meta charset="utf-8">
  <link rel="index" href="toc1.php" type="application/json">
</head>

My toc1.php was file:

<?php
  $username = $_GET['username'];
  $papername = $_GET['papername'];

  header('Content-Type: application/json');
  $username = json_encode($username);
  $papername = json_encode($papername);
?>

[{
"url": <?php echo '<a href="http://www.yoozpaper.com/cover.php?
username=' . $username . '&papername=' . $papername . '" ></a>';?>
},
{
"url": <?php echo '<a href="http://www.yoozpaper.com/tocindex.php?
username=' . $username . '&papername=' . $papername . '" ></a>';?>
},]

What about just removing the json_encode??

The json_encode function makes json object form array:

$json = array();
$json['something'] = "something else";
$json['and_again'] = "more things";

And then json_encode($json) returns:

{
     "something": "something",
     "and_again": "things"
}

So json encode a string:

$username = "John Doe";
echo json_encode($username);

Will result in something as "John Doe" or an error

I recommend following:

$list = array();

$objItem = new stdClass();
$objItem->url = '<a href="…?username=' . $username . '&papername=' . $papername . '"></a>';
$list[] = $objItem;

// add more items

And finally, output that:

echo json_encode($list);

The header() call must be the very first line of the file, see manual. So change it to

<?php
header('Content-Type: application/json');

$username = $_GET['username'];
$papername = $_GET['papername'];

$username = json_encode($username);
$papername = json_encode($papername);
?>

And from where the GET variables are supposed to come? You probably want to change the link to

<link rel="index" href="toc1.php?username=foo&papername=bar" type="application/json">
