PHP - Find Specific Value in Array (multidimensional) - php

Question

I have the an array, in which I store one value from the database like this:
$stmt = $dbh->prepare("SELECT token FROM advertisement_clicks WHERE (username=:username OR ip=:ipcheck)");
$stmt->bindParam(":username",$userdata["username"]);
$stmt->bindParam(":ipcheck",$ipcheck);
$stmt->execute();
$data = array();
$data = $stmt->fetchAll(PDO::FETCH_ASSOC);
So, that gives me: array("token","token");
When I print it:
Array ( [0] => Array ( [token] => 677E2114AA26BA4351A686917652C7E1BA67A32D ) [1] => Array ( [token] => C42190F3D72C5BB6BB6B68488D1D4662A8D2A138 ) )
I then have a loop, that loops all the tokens. In that loop, I try to search for a specific token, and if it that token matches, it will be marked as "seen":
function searchForId($id, $array) {
foreach ($array as $key => $val) {
if ($val['token'] === $id) {
return $key;
}
}
}
This is my loop:
$icon = "not-seen";
foreach($d as $value){
$token = $value["token"];
$searchParam = searchForId($token, $data);
if($searchParam == $token){
$icon = "seen";
}
}
However, searchForid() simply returns 0
What am I doing wrong?

Ok, here you can see a PHP fiddle that works
$data = array();
$data[] = array('token'=>'123');
$data[] = array('token'=>'456');
function searchForId($id, $array) {
foreach ($array as $key => $val) {
if ($val['token'] === $id) {
return true;
}
}
return false;
}
$icon = "not-seen";
foreach($data as $value){
$token = $value["token"];
$searchParam = searchForId($token, $data);
if($searchParam){
$icon = "seen";
}
}
echo $icon;
It echos 'seen' which is expected since I compare the same array values, now assuming that your $d variable has different tokens, it should still work this way.
That means that your $d array does not contain what you claim it contains, could you print_r this variable and post it in your answer?
