Curso de PHP🐘 y MySql🐬 [77.- Borrar registros con PDO]

En este tutorial vamos a aprender a borrar registros con PDO pero lo aremos con consultas preparadas para evitar las inyección de sql.

Eso lo aremos con este codigo:

$query="DELETE FROM productos
WHERE id=:id;";
prepare($query);
bindParam(':id',$id);
if(execute()==true){
    return true;
}
else{
    return false;
}
