I’m trying to convert my SQL result into a class using PDO::FETCH_CLASS.

The code was working fine, until I encountered a query that generates 83 rows. The query returns two columns, one of type int and one of type text.

This is the error message:

 Fatal error: Uncaught TypeError: AppModelsBibliaLectio::add():
 Argument #1 ($bibliaTextus) must be of type AppModelsBibliaTextus,
 array given,  called in
 /MYROUTE/src/App/Domain/Infrastructure/Mapper/Biblia/PdoBibliaMapper.php on line 60  
 and defined in /MYROUTE/src/App/Models/BibliaLectio.php:10

The code I’m using is as follows:

PdoBibliaMapper

//..

$bibliaLectio= new AppModelsBibliaLectio();
$stmt=$this->pdo->run($sql,$params);
$stmt->setFetchMode(PDO::FETCH_CLASS, 'AppModelsBibliaTextus');
while ($row = $stmt->fetch())
{
    $bibliaLectio->add($row); #Line 60
}

BibliaTextus

namespace AppModels;

class BibliaTextus
{

    private int $v;
    private string $t;

    public function toHtml()
    {
        return sprintf('<span class="versiculo">%s</span> %s',$this->v,$this->t);
    }
}

BibliaLectio

namespace AppModels;

class BibliaLectio
{

    private array $list;

    public function add(BibliaTextus $bibliaTextus) #Line 10
    {
        $this->list[]=$bibliaTextus;
    }

    public function toHtml()
    {
        $s='<h1>Texto Bíblico</h1><div class="textus-title"><p>';
        foreach ($this->list as $t)
        {
            $s.=$t->toHtml();
        }
        $s.='</p></div>';
        $s.='<p class="bibliaTextus"><a href="https://example.com/biblia" target="_blank" rel="nofollow">Some Text</p>';
        return $s;
    }
}

Why does the code fail with a result of 83 rows and with smaller results it works fine and how could I solve this problem?
