Can't get simple if / else statement to work

I am searching a table in my DB to return a tick if a name matches a $_GET['name'] variable that I have passed in the URL.

I want a tick displayed if the name exists and a cross if it does not.

The purpose is to populate a rota / timetable of availability.

The code I have so far;

<?php foreach($rota_sun as $rota_sunday): ?>
       <?php if(strpos($rota_sunday['person_name'], $_GET['name']) !== false) { ?>
              <span style="color:green; font-size:22px;"><i class="fa fa-check" aria-hidden="true"></i></span>
              <?php } else { ?>
              <span style="color:red; font-size:22px;"><i class="fa fa-times" aria-hidden="true"></i></span>
      <?php } ?>
 <?php endforeach; ?>

My code for the query is;

$query = "SELECT
                rota_sunday.id AS rota_id,
                rota_sunday.person_id,
                rota_sunday.person_name
            FROM rota_sunday WHERE rota_sunday.person_name = '$_GET['$name']'
        "; 
    try 
    { 
        $stmt = $conn->prepare($query); 
        $stmt->execute(); 
    } 
    catch(PDOException $ex) 
    { 
        die("Failed to run query: " . $ex->getMessage()); 
    } 
    $rota_sun = $stmt->fetchAll(PDO::FETCH_ASSOC);

My table contains three rows;

  1. id
  2. person_id
  3. person_name

The array I'm using is;

Array
(
    [0] => Array
        (
            [rota_id] => 16
            [person_id] => 0
            [person_name] => Gina
        )

)

You'll see that Gina exists - so if ?name=Gina is in my URL a tick should be shown but ?name=Fred or ?name=John etc is in my URL a cross should be displayed.

Issue: The tick is displaying when the name exists but the cross isn't displaying when the name doesn't exist.

A working example:-

<link rel="stylesheet" href="font-awesome-4.6.3/css/font-awesome.min.css">

<?php
  error_reporting(E_ALL); //check all type of errors
  ini_set('display_errors',1); // display those if any happen
  $_GET['name'] = 'fiksun';
  $rota_sun = Array
(
    '0' => Array
        (
            'rota_id' => 16,
            'person_id' => 0,
            'person_name' => 'Gina'
        ),
    '1' => Array
        (
            'rota_id' => 16,
            'person_id' => 0,
            'person_name' => 'fiksun'
        )

)
?>
<?php foreach($rota_sun as $rota_sunday): ?>
    <?php if($rota_sunday['person_name']== $_GET['name']) { ?>
        <span style="color:green; font-size:22px;"><i class="fa fa-check" aria-hidden="true"></i><?php echo $rota_sunday['person_name'];?></span>
      <?php } else { ?>
        <span style="color:red; font-size:22px;"><i class="fa fa-times" aria-hidden="true"></i><?php echo $rota_sunday['person_name'];?></span>
  <?php } ?>
<?php endforeach; ?>

Output:- http://prntscr.com/cf4ecd

Note:- download font-awesome library from here:- http://fontawesome.io/get-started/

Put the complete folder in your current working directory

Add the css file correctly.

this is working directory structure:- http://prntscr.com/cf4fuk

Change your query:-

$query = "SELECT rota_sunday.id AS rota_id, rota_sunday.person_id AS person_id, rota_sunday.person_name AS person_name FROM rota_sunday WHERE rota_sunday.person_name Like '%".$_GET['$name']."%'";

This query will select just one person from DB.

$query = "SELECT
            rota_sunday.id AS rota_id,
            rota_sunday.person_id,
            rota_sunday.person_name
        FROM rota_sunday WHERE rota_sunday.person_name = " . $_GET['name'] . "LIMIT 1"; 
try 
{ 
    $stmt = $conn->prepare($query); 
    $stmt->execute(); 
} 
catch(PDOException $ex) 
{ 
    die("Failed to run query: " . $ex->getMessage()); 
} 
$rota_sun = $stmt->fetch(PDO::FETCH_ASSOC);

If this person exist then $rota_sun will contain result if not then this will return false and you will get the red cross.

   <?php if($rota_sun) { ?>
          <span style="color:green; font-size:22px;"><i class="fa fa-check" aria-hidden="true"></i></span>
   <?php } else { ?>
          <span style="color:red; font-size:22px;"><i class="fa fa-times" aria-hidden="true"></i></span>
   <?php } ?>
