Question

I’m having problem acessing a JSON element after a sqlite query.

I have the following code:

$queryIdClient = "SELECT seq FROM sqlite_sequence WHERE name = 'clientes';";
$id;

if($result = $db->query($queryIdClient)) {
    $row = $result->fetch(PDO::FETCH_ASSOC);
    $row = json_encode($row);
    echo $row;
}
else {
    die($error);
}

The echo $row gives me {“seq” : “10”}.

I want to pass the value 10 to the $id variable. I’ve tried a lot of ways, but I can’t get it to work.

Shouldn’t it work with $id = $row->seq; ?

There’s no need for the json_encode() there:

$queryIdClient = "SELECT seq FROM sqlite_sequence WHERE name = 'clientes';";
$id;

if($result = $db->query($queryIdClient)) {
    $row = $result->fetch(PDO::FETCH_ASSOC);
    // $row = json_encode($row);
    $id = $row['seq'];
    echo $id;
}
else {
    die($error);
}
