LIKE SQL with parameters throwing Invalid Parameter Number - php

Question

So I'm trying to use a "LIKE" in the SQL, basically to see if a player is in a team already. Here's the code I have:
$checkifonlytwo = "SELECT * FROM sg_turn_teams WHERE joinid = :joinid AND players LIKE '%:ownerid,%'";
$paramstwo = array(
":joinid" => $joinid,
":ownerid" => $_SESSION['user']['id']
);
try{
$stmttwo = $db->prepare($checkifonlytwo);
$resulttwo = $stmttwo->execute($paramstwo);
}
catch(PDOException $ex){
die("Failed to run query #2: " . $ex->getMessage());
}
Also as you can see I want it to be LIKE '%1,%' for example, so the comma at the end too.
My table structure looks like this.
EDIT, the players is going to be like "1,2,3" without the names because the users are able to change their name. The picture is with names, but it's supposed to be 1,2,3

Foreword. I decided to make this a community wiki. I did not want to gain anything from this, except for the OP and others visiting the question.
As I said in comments, you're going about it the wrong way with the comma in there ownerid,.
What you need to do is implode on the array and using IN().
Borrowed from https://stackoverflow.com/a/12151295/
$e = 0;
while($e<$num1){
$units = 0;
$r = 0;
$SO_Line_Item=mysql_result($result1,$e,"SO_Line_Item");
foreach ($Boxes[$e] as $a => $b)
{
$zzz[] = $Boxes[$e][$r];
$ce = count($Boxes[$e]);
$r++;
}
//end inner foreach
$products = implode(',', array_fill(0,$ce, '?'));
$db = new PDO('mysql:host=192.168.1.197 ;dbname=Tracking', $dbuser,$dbpass);
$stmt = $db->prepare("SELECT Box_Num,Timestamp,E3_SN,Assy_Status FROM Current_Box WHERE Box_Num IN( $products )");
$stmt->execute($zzz);
$results = $stmt->fetchAll(PDO::FETCH_ASSOC);
}
unset($zzz);
$e++;
}
and from https://stackoverflow.com/a/2814703/
$ids = array(2, 4, 6, 8);
// prepare a string that contains ":id_0,..,:id_n" and include it in the SQL
$plist = ':id_'.implode(',:id_', array_keys($ids));
$sql = "SELECT * FROM someTable WHERE someId IN ($plist)";
// prepare & execute the actual statement
$parms = array_combine(explode(",", $plist), $ids);
$stmt = $PDO->prepare($sql);
$rows = $stmt->execute($parms);
From comments:
"You might want to use association tables rather than storing the information the way you are storing it. – Maximus2012"
As mentioned in the comments, some questions/answers from SO that demonstrate the concept of Association tables along with composite primary keys:

How to use an MySQL association table to return categories not currently assigned to an entry
If OP decides to go with this structure then the queries would need to be changed to make use of LEFT JOIN and/or use a sub-query with IN clause. There are plenty of examples of both on SO. One that I could find with a simple search (please ignore the slow query part and look at the examples to demonstrate the concept):
MySQL - SELECT WHERE field IN (subquery) - Extremely slow why?
