Question

My array would only get a 0 or a 1. I’m using PDO statement for mysql, and this is what I have

$result = $fetching -> fetch();
$first_result = $result[0];

if($first_result === 0){
//do something...
}else{
echo "testing";
}

I’m always getting the testing no matter what, if its 0 or not. I’ve echoed out the $first_result[0] for testing purposes and it will tell me what the value is. So I know that the value will shoot out either 0 or not 0. But when it is 0, it still echos out testing.

Help please?

Thank you!

Answer 1

First of all try to put == not type equivalence. And Second I always use this to check if there any record:

$q = $pdo->prepare('Your SQL');
$result = $q->execute($params);
$rows = $q->fetchAll(PDO::FETCH_ASSOC);
if (!count($rows) || !$result)
{
    echo 'No rows or error';
    // To output error $pdo->errorInfo();
}
else
{
    $el = $row[0];
}

Hope that helps.
